Crop-Livestock Integration at Green Fire Farm

DeLisa Lewis, PhD

What do the North American Dust Bowl of the 1930s and the current global experiences of climate change have in common? Of course, both are understood as environmental disasters with humans as major contributors. But, if you answered with either ‘farmers’ or ‘soils,’ or more ideally, both, you’d be hearing a celebratory ding-ding-ding right about now.

For farmers and their soils, however, the ‘answers,’,in the form our day-to-day management are not so simple. Environmental historians have uncovered a picture of the Dust Bowl that is also less simple than the above equation, (e.g. Worster, D. 2004; Cunfer, 2004). True to the story I would like to tell here, these historians do focus on some of the challenges of long-term management of soils. Geoff Cunfer, an environmental historian of the Great Plains, found just how much ‘manure matters’ and asserted, “Through 10,000 years of farming on five continents by hundreds of diverse human cultures, only a handful of solutions to soil fertility maintenance have emerged” (Cunfer, 2004: p. 540).

What I’ve learned from reading environmental and agricultural history accounts, as well as reviewing the findings from long-term agricultural research studies1 is that careful, and regionally specific considerations of soils and climates are key nodes for fine-tuning systems. Perhaps more importantly, farming operations, including organic ones, have become increasingly specialized with livestock and manure here and vegetables over there. The lessons from history and long-term agricultural research, point towards diversity, and combined strategies for soil fertility or soil health.

I did not reach a place of digging around the archives or agriculture research station reports until I had close to 15 years of practice with soil management on certified organic vegetables farms. My farming systems experience to that point was within specialized, vegetables-only operations where I managed the soil preparation of the fields as well as windrows of compost with the front-end loader on my tractor.

When I arrived in British Columbia to learn more about the science behind soil management practices, some of the immediate lessons learned centered on the very different soil types, climate characteristics, and economic and cultural realities here. I now have just over a decade of ‘living here’ experience in the Coast-Islands region of BC, and am moving into year five operating our family-owned farm in the Cowichan Valley. That background is meant to highlight that I am still learning, and what I want to share for the purposes of this article on soil health and climate change, is my journey so far with integrating livestock with vegetables on Green Fire Farm.

Although coping with ‘too much and too little’ available water is not new to farmers in the Coast-Islands regions of BC, frequent and extreme weather events do present a new set of challenges. Faced with the demands of producing high quality product in competitive markets, and rising costs for farm inputs, we decided to pursue a number of different strategies to meet the goals of farm profitability, risk reduction, and (my personal favourite) soil health.2 The overall strategy is diversification, both in the fields and in terms of different revenue streams for the farm.

The soils and climate of our farm are well suited to a mixed farming operation, with Fairbridge silt loam soils3 and a Maritime Mediterranean climate. The soil landscape would be described as ‘ridge and swale’, with differing slopes and mixed drainage patterns interspersed through the fields. The drainage limitations of these soils and the erosion prone sloping areas are key pressure points for early spring and late fall field soil preparations. Though I have attempted to address some of these potential challenges to soil health with carefully timed tillage,4 and the use of a spader to reduce mechanical disturbance, the loss of production from one to two weeks at both ends of the growing season can be a costly hit to our farm profitability.

With that in mind, I see necessity as a driver with my decision-making around farm enterprise diversification. I did not arrive on our farm in the Cowichan with all the knowledge or skills required to integrate livestock with our vegetable production, but I did arrive with a keen interest in learning what mix of systems could optimize the opportunities and limits of our farm’s unique mix of soils, climate, and markets. Nearly five years in, we grow and sell a diverse mix of annual vegetables, perennial fruits, hay, and pastured pork. In recognition of the limits to my own management capacity, the addition of each new layer of complexity to the system is small and incremental.

I braved the unknowns of bringing in weaner piglets in the first season because we did not have enough irrigation water at that time to set up the vegetable systems that were most familiar to me. We began our learning with pastured pig systems with a total of eight piglets.

Last spring, we found another certified organic farm in our valley who were ready to sell their small herd of four lowline Angus beef cows. With their mentorship and guidance, I’ve added a system of ‘modified’5 intensive grazing to our pastures. In addition to purchasing the cows, our investments were increases to our electric fencing equipment used with the pigs, additional livestock watering tanks, and a used set of haying equipment.

This spring, I plan to set up smaller paddocks using the electric fencing where I want the cows to terminate the overwintered cover crops. This would be my ‘holy grail’6 system for putting in practice both soil health principles and climate friendly strategies, and much additional research will be needed to evaluate the return on investment and to quantify the contributions to soil health or climate impacts mitigation.

Currently, I have more questions than answers with respect to a full assessment of how this crop-livestock integration performs on our farm. As one part of our response to that, we will be expanding our record-keeping systems in an effort to learn our way towards an evaluation. Connecting our farm efforts to the work of others as recorded in the pages of this magazine, Corine Singfield7 and Tristan Banwell8 are both carrying out promising on-farm research focusing on livestock integration and MIG. Stay tuned for more details!

Healthy Soils Yield Resilient Operations

Three case studies examine soil management practices in the face of climate change

By Rachel Penner, BC Agriculture & Food Climate Action Initiative

Improving soil health is one way producers can increase the resilience of their operations in the face of climate change. The BC Agriculture & Food Climate Action Initiative (CAI) has supported multiple projects, with funding from the provincial and federal governments, evaluating practices to maintain or improve soil health. Case studies in three regions of the province offer some practical takeaways for farmers looking to adapt to changes in climate.

Okanagan: Adding Compost and Reducing Irrigation

Climate change is expected to increase average temperatures and lengthen the growing season in BC’s Interior, enabling cherry producers to expand production northward and grow crops at higher elevations. However, expanding production may be limited by challenges with managing soil pathogens and by water availability.

A three-year research project focusing on cherry production in the Okanagan resulted in two key findings: 

  • adding compost to old and new orchards helped maintain soil health
  • reducing post-harvest irrigation by 25% did not impact fruit yield or quality

Gayle Krahn, the horticulture manager at Coral Beach Farms, participated in the project. “It’s through these trials that growers gain the confidence needed to invest in mulches,” says Krahn. “As well, the results from the deficit irrigation studies gave us a good handle on how much water we need in our orchards. Climate change could affect our water supply, so we need to be mindful of our water usage while ensuring we can continue to grow healthy crops.”

Louise Nelson with the Biology department at UBC Okanagan led the three-year experiment. Researchers monitored the effects of compost and mulch applications, comparing results with controls in two new and one established orchard, and assessed the impacts of post-harvest deficit-irrigation.

The study, completed in 2018, revealed that adding compost to cherry orchards had the following impacts on the soil:

  • increased soil organic matter, total carbon and nitrogen, other mineral nutrients and pH
  • increased percentages of nitrogen, phosphorus and potassium in leaves after two years
  • increased fruit firmness and stem pull
  • tended to increase total nematode abundance in soil
  • tended to decrease plant parasitic nematodes in plant roots and soil
  • decreased colonization of roots by arbuscular mycorrhizal fungi

“I would definitely recommend that growers invest in compost as it helps build soil structure, reduce moisture loss and keep soils cool during summer heat,” says Krahn. “The result is increased root growth and a healthier tree, which equates to growing quality fruit.”

The study also found that a 25% reduction in post-harvest irrigation had no impact on fruit yield and quality, stem water potential, tree growth, or leaf mineral content, giving producers greater assurance that they can safely decrease water usage in their cherry orchards post-harvest.

Delta: Using and Maintaining Tile Drains

Climate projections indicate that winter rainfall will increase and extreme rainfall events will double in frequency by the 2050s in BC’s Fraser River delta. This increase in moisture could prevent farmers from getting onto waterlogged fields, either to plant or to harvest, and could also increase soil erosion, nutrient runoff, and damage to crops.

However, effective spacing and maintenance of tile drains can increase the ability of producers to work their fields.

A project in Delta, completed in July 2017, evaluated practices for improving on-farm drainage management as a way to adapt to wetter spring and fall conditions. The project, led by three researchers in the Faculty of Land & Food Systems at UBC in collaboration with the Delta Farmers’ Institute, the Delta Farmland & Wildlife Trust and local farmers, set up demonstration sites on two fields and monitored practices across a total of 30 fields in multiple locations.

The results of the two-year project indicated the following:

  • Using tile drains in vegetable crop fields increased workable days by 8% and by 14% when pumps where also used. (The impact was negligible for blueberry fields.)
  • Drain tiles spaced at 15 feet allowed soil to dry faster in the spring than drain tiles spaced at 30 feet.
  • Cleaning tile drains resulted in 12 extra workable days per year at a cleaning cost of $10/additional workable day/acre.

Central Interior: Practising Management-intensive Grazing

Management-intensive grazing, a practice that involves planned grazing and rest periods for pastures, is a context-dependent practice that can vary from one rancher and pasture location to the next, making it difficult to test the impact it has on soil.

A four-year project in BC’s Central Interior, completed in spring 2017, compared grazing practices and used traditional soil sampling methods, plant community composition and remote sensing to measure soil carbon. Results confirmed that management-intensive grazing increased soil carbon, which has important implications for soil health.

“What got me interested in grazing-management practices was the enthusiasm of the ranching community,” says Lauchlan Fraser, a professor at Thompson Rivers University who led the project. “I wanted to see if some of the claims that were being made held up.”

The data showed that, for intensively managed pastures, total carbon was 28% greater and organic carbon was 13% greater when compared to extensively managed pastures. It is widely agreed that this stored carbon is linked to soil health, and a fact sheet for the study stated that: “Benefits associated with greater soil carbon include soil moisture retention, erosion control and species biodiversity.”

These outcomes were experienced by the producers who participated in the study. All the ranchers reported that they saw improved soil moisture retention, which would help them cope better in a drought year. They also thought the practice would work as a tool to control invasive species and improve plant and animal diversity, both important contributors to resilient grazing systems.

“It would be worthwhile to follow up with doing the research required to test how biodiversity and soil moisture are influenced,” says Fraser.

While carbon sequestration is primarily associated with climate change mitigation, the project’s final report found additional implications for climate change adaptation: “Flexibility of electric fencing, and actively managing cattle on a daily basis, was identified to be an adaptation strategy, since a rancher is able to adapt his or her practices based on conditions which vary from one year to the next,” says Fraser.

Project Funding and Detailed Reports

For all three of the projects, funding was provided by the Governments of Canada and British Columbia through the Canadian Agricultural Program as part of the Farm Adaptation Innovator Program delivered by CAI.

Meat from Here

Challenges to Localizing Meat Production

Tristan Banwell

Consider for a moment the complexities of the industrial meat supply chain. Livestock could be born on one farm, sold and moved to another location for finishing, trucked to yet another premises for slaughter. The carcass will be butchered and processed at a different location, and sold at another (or many others), and could be sold and reprocessed multiple times before it ends up on a customer’s plate. The farm, feedlot, abattoir, and processing facility could be in different provinces, or they could be in different countries. It is a certainty that some of the meat imported to Canada comes from livestock that were born in Canada and exported for finishing and/or slaughter before finding their way back to a plate closer to home.

A 2005 study in Waterloo, Ontario(1) noted that beef consumed in the region racked up an average of 5,770 kilometres travelled, with most coming from Colorado, Kansas, Australia, New Zealand, and Nebraska. The author concluded that imported beef products averaged 667 times the greenhouse gas (GHG) emissions of local beef, and the emissions were at the top of the chart among foods studied. Meat production is low-hanging fruit for reducing pollution and improving the environmental footprint of agriculture, and not just through reducing transportation. Implementation of managed grazing and silvopasture ranked #19 and #9 respectively in terms of their potential impact on climate by Project Drawdown, in the same neighbourhood as other exciting forestry and agricultural innovations, family planning, and renewable energy projects.(2) Organic methods further reduce negative externalities by nearly eliminating inputs such as antibiotics and pesticides, which are used heavily in conventional settings.

Much of the agricultural land in our province is also well suited to livestock according to the Land Capability Classification for Agriculture in BC. In fact, 44% of BC’s ALR lands are categorized in Class 5 & 6, meaning the soil and climate make them suitable primarily for perennial forage production. Looking beyond the ALR boundaries, 76% of all classified arable land in BC is in Class 5 & 6.(3) Of course, there is land in Class 4 and better that could also be best suited to livestock production, and livestock can be beneficially integrated into other types of crop and orchard systems. As farmland prices spiral higher, aspiring farmers could be looking further down this classification system for their affordable opportunity to farm. Livestock production and direct marketing meats can be an attractive enterprise for a new entrant, especially given the exciting opportunities for regenerative organic methods and an increasingly engaged and supportive customer base.

Unfortunately, there are numerous challenges facing both new and established small-scale meat producers in their efforts to implement improved methods and supply local markets. The cost-slashing benefits of economies of scale in livestock enterprises are staggering, and even the leanest, most efficient small livestock enterprise will incur disproportionately high production costs. Sources of breeding stock, feeder stock, chicks, and other outsourced portions of the life cycle chain can be distant, and finding appropriate genetics for a pasture based or grass finishing operation can be next to impossible. Given the geographic fragmentation of the province, managing the logistics of other inputs like feed, minerals, equipment, and supplies can be a Sisyphean task.

The regulations around raising livestock, traceability, slaughter, butchery, and meat processing are complex and span from the federal level (Canadian Food Inspection Agency, Canadian Cattle Identification Agency, Canadian Pork Council) through provincial bodies (BC Ministry of Agriculture Food Safety & Inspection Branch, Ministry of Health, supply management marketing boards), regional groups (regional health authorities, regional district governments) and right down to municipal government bylaws. The tables are definitely tipped in favour of large-scale commodity producers, who have the scale to hire consultants and meet more expensive requirements, and who are beholden to regulators for only one product or species. For a small scale diversified livestock operation, compliance becomes expensive and time consuming as a producer navigates the rules, requirements, and permits for multiple species.

Should a farmer manage to jump some hurdles and establish an enterprise in compliance with regulations, they may find that their growth is capped not by the capacity of their land base or even their markets, but rather by regulatory factors and supply chain limitations. There are particularly low annual production limits in supply-managed poultry categories—2000 broilers, 300 turkeys, 400 layers per year—and that is after applying as a quota-exempt small-lot producer. There is currently no path to becoming a quota holder for small pastured poultry operations. The sole quota-holding pastured poultry producer in BC is currently under threat from the BC Chicken Marketing Board, which requires a set production per six week cycle year round, rather than the seasonal production necessitated by outdoor poultry systems. The BC Hog Marketing Scheme allows a more generous 300 pigs finished per year, and there is no production regulation for beef cattle nor for other species like ducks, sheep, and goats.

Regardless of what livestock species a farmer raises, eventually they must go to market. For most commodity cow-calf operations and some other livestock enterprises, this can mean selling livestock through an auction such as the BC Livestock Producers Cooperative. However, many small scale producers prefer to maintain control of their livestock, finishing them on the farm, arranging for slaughter, and wholesaling or direct marketing the meat. This can help a farm retain more of the final sales price, but adds another layer of complexity around slaughter and butchering, as well as storage, marketing, and distribution.

In BC, there are five classes of licensed abattoirs in operation, including 13 federally-inspected plants, 63 provincially-inspected facilities (Class A & B), and 66 licensed Rural Slaughter Establishments (Class D & E).(4) Federally inspected plants are under jurisdiction of the CFIA and produce meat that can be sold across provincial and international borders. The two classes of provincially licenced plants include inspected and non-inspected facilities. Class A and B facilities are administered by the Ministry of Agriculture Meat Inspection Program, have a government inspector present for slaughter, and are able to slaughter an unlimited number of animals for unrestricted sale within BC. Class A facilities can cut and wrap meat, whereas Class B facilities are slaughter-only with no cut/wrap capacity.

Class D and E slaughter facilities, also known as Rural Slaughter Establishments, are able to slaughter a limited number of animals per year without an inspector present after completing some training, submitting water samples and food safety plans, and having the facility inspected by a regional health authority. A Class D facility is limited to 25,000 lbs live weight per year, can slaughter their own or other farms’ animals, and can sell within their regional district only, including to processors and retailers for resale. This class of licence is limited to 10 regional districts that are underserved by Class A and B facilities. Class E licenses are available throughout the province at the discretion of Environmental Health Officers. This type of licence allows slaughter of up to 10,000 lbs live weight of animals from the licensed farm only, and allows direct to consumer sales within the regional district, but not for further processing or resale.

Despite multiple options for abattoir licensing, small farms are underserved and slaughter capacity is currently lacking in BC. Running an abattoir is a difficult business, with significant overhead costs and strong seasonality, and there is a shortage of qualified staff in most areas of the province. On-farm slaughter options may sound appealing, but the costs associated and low limits on the number of animals per year make small on-farm facilities a difficult proposition. Producers will find it difficult or impossible to have their livestock slaughtered throughout the fall, which is busy season for abattoirs for exactly the reasons producers need their services at that time. Some poultry processors are beginning to set batch minimums above the small lot authorization numbers to eliminate the hassle of servicing small scale producers.

Clearly, improvements can be made to increase the viability of local and regional meat production in BC. This year, meat producers throughout the province came together to form the Small-Scale Meat Producers Association (SSMPA) with an aim toward creating a network to share resources and to speak with a common voice to move systems forward in support of producers raising meat outside of the conventional industrial system.

The BC provincial government has reconvened the Select Standing Committee on Agriculture, Fish & Food, and the first task of this group is to make recommendations on local meat production capacity.(5) The SSMPA has been active in these discussions, as well as earlier consultations regarding Rural Slaughter Establishments, and looks forward to encouraging a more localized, place-based meat supply in BC.

Wildfires scour the landscape around Riparian Ranch

This story first appeared on the Young Agrarians website.

Protecting my home was just something I had to do. People keep commenting on how brave I was—but I like to think everyone has some grit inside of them somewhere to fight when they have to. My heart goes out to those who have lost their homes and those who are still fighting to save homes.

We bought 256 acres of cleared but poor quality (and consequently, affordable) land out in the middle of nowhere. My husband wanted to live off the grid and I grew up off grid, so it wasn’t a huge stretch buying this place. With technology these days we have a lot more creature comforts available off grid than I did as a kid in the ‘90s.

The only catch was my hubby has a company down in Burnaby so I’m up here by myself 90% of the time learning to do a lot of things I never dreamed I’d be doing. Since the land needed improving and was not fenced we bought some solar powered fencers and step in posts and got to work. With affordable solar fencers, the voltage isn’t that much, so you really have to work with the psychology of the animals. If they’re not satisfied they will just leave. Solar fencers definitely let you know if your animals are happy in a hurry.

I moved them last year every 24 to 48 hours, and I saw a good deal of improvement. This year we dedicated a lot of time to fencing. I would only move them once per week but it still did what it was supposed to do.

The forage stayed green a lot longer than the ungrazed areas despite extreme drought conditions. Once the fire started I kind of knew we were in a good spot. Some of my friends, bless their hearts, were heavily involved in helping people evacuate livestock. They were quite insistent that I should get my animals out of there, but I refused. They’re as much my coworkers as they are livestock and they had as much of a job to do during the fire prep as I did.

I put my cows and horses in the hay field (the only area that had not yet been grazed…lots of fuel growing in peat soil) and started to move the step in posts closer to the forest every time they had finished a section. The fire danced around me for a month and finally made a pretty decisive b-line for me. Once the fire started to come I moved the posts back to the grazed area so they wouldn’t burn and set up a second water source in case the first source had fire near it. I moved the animals’ loose mineral tub back to where I thought was safest so they knew that was the best area to hang out, and that was that.

Intensively grazed pasture stopped the spread of fire
Intensively grazed pasture stopped the spread of fire

We watched the fire come in on all sides in one wild night. There’s no way I can describe the power of this fire so I’ll just give a rundown of what happened. August 11—I kind of knew it was the day the fire would come. Five weeks of waiting, watching, and preparing. That morning I got my chores done early and headed inside for a nap. I woke up in the afternoon to roaring fire on three sides and hot—I mean HOT—wind.

My neighbours Becca and Darrel showed up not long after. Darrel was worried about a cabin in the woods, Mikey’s cabin, and wanted to go check that the pump was still running. He went one way and Becca and I went the other way to break a dam upstream to let more water in to the creek for Mikey’s pump. There we are, two girls sitting in the mud listening to the roar of the fire behind us. Once we started heading back we quickly realized the fire was already almost at my property and became pretty worried about Darrel. He never made it to Mikey’s pump because the fire was already in the surrounding forest. We all figured the cabin was a pile of ash.

Another neighbour, Robert, showed up at that point, as did the one and only guy we had ever seen from Quesnel (who is supposed to be managing this fire). He quickly left. There wasn’t much we could do. We stood and watched the flames come in on all sides, completely surrounding us and cutting off all exits.

Once the fire had come in close I turned the waterfowl and billy goat loose and went in to the field that the goats and dogs were in. I called them all out of their huts as I was worried the roofs might catch a spark and led them to the sprinklers. They seemed to understand what I was showing them, as they never walked back in to their huts that night. I was not concerned about the cows and horses out in the hay field. We do managed intensive grazing, which proved very effective at stopping the fire in its tracks. I was pretty confident they were completely safe.

Then the smoke came down on us and for most of the evening we were choking on smoke and couldn’t see a thing. We had a couple little hot spots in paddocks and pastures throughout the night but they either burnt themselves out or were put out.

About midnight the fire calmed down on the Northern side and much to our surprise we heard the buzz of Mikey’s pump in the distance—the cabin had survived. The water from the dam had finally made its way down to us so we used it to put out a few fires and wet certain areas down. At the end of the night we all stood in awe of what had happened and what was still going on. Robert cut his way through my driveway to get home and we headed to bed. Darrel stayed up to keep watch.

The next day my husband finally was able to make it home and the fire ripped through two of our neighbour’s properties (they both made it). We weren’t able to be there for either of them but we cut our way through and went to help as soon as we could. Later that evening Robert’s wife Mamie said, “Who’s even going to believe this? Two people in their mid ‘60s running around with hoses fighting a wildfire.”

The fire burnt right up to where they had grazed and stopped. It was very hot and burnt pretty much anything in its path including green marshes and willow bushes. In one spot where I had just grazed but didn’t move the posts back to the grazed area the fire actually burnt the hot tape but not the posts because the cows had reached under and grazed around them.

Peat soil is quite notorious for burning underground for months…even through the winter…but for whatever reason the field appears to be just fine. My poor neighbour who owns another part of this field about two km away is still battling underground hot spots in his peat soil and he had the fire pass through one day after me. We’ve been over a few times to help him put out spots and move hay.

We have major wolf problems in the winter so fencing and LGDs (livestock guard dogs) are actually more important than this fire ever was. I shocked the heck out of the structure protection crew when I told them my puppies in training were more important than their hoses and I would NOT move them out of their field. Never a dull moment around here.

Horse and cows happy to be safe and sound!

None of us are able to get fire insurance due to our remote off the grid locations, so of course we all stayed to fight. We have been spending every day since checking on the properties and putting out little hot spots. It won’t be something I will ever forget, nor will this area ever look the same within my lifetime.

In the end, we didn’t lose anything to the fire. There’s no damage other than a few singed fence posts and of course my canoe I forgot about until we had gone to break the beaver dam when the fire was here. All the prep I did made it a fairly easy experience and the people that stayed with me of course helped immensely. I was never very good at studying for tests in school but this one I feel like I did my homework and was pretty well prepared for.

The fire is still blazing to the East of me. I can see plumes of smoke rising as I type this but for the most part we are safe. It’s never a dull moment here but I think it is safe to say this was one of the most exciting.

Or: How to Never Have to Chase Sheep in Circles Around a Paddock Ever Again!

Sara Sutherland

Many people believe that sheep are stupid. Even people who have never worked with sheep tend to think that sheep are stupid. Broadly speaking, there are two categories of things that sheep do that make people think they are stupid. Firstly, sheep mob together, follow each other, follow the bellwether up the steps to the slaughterhouse, and generally show a lack of independent thought. Secondly, sheep scatter, run the wrong way, get out of fences, and when you get almost all the sheep into the pen and close the gate one will inevitably spin around and run out just before you get the gate closed. (If you think about it, this isn’t fair—dumb if you do and dumb if you don’t!)

When you work closely with sheep, you begin to realize that they also show signs of intelligence. Sheep will watch when you fix a hole in the fence, then go and check if it’s really fixed. Sheep will teach each other to get into a feeder that is supposed to only let lambs eat. A researcher in the UK, Keith Kendrick, studied facial recognition in sheep. Sheep would push the button beside the photograph of a sheep they knew, a flockmate, instead of a sheep they didn’t know. They could recognize over 30 individuals, and remember for at least three years after the last time they had seen the animal in the photograph!

So if sheep are so intelligent, if they have this capacity for recognition and learning and memory, why do they do stupid things?

Sheep don’t have a lot of natural defences. They don’t have sharp teeth, they don’t have long fangs, they don’t shoot lasers from their eyes (fortunately). Because they are prey animals, they are highly motivated to avoid being eaten. The most dominant sheep in a flock is not the leader, the most dominant sheep is in the middle where it is safest. When there is a group of animals of similar size running past each other, it is very difficult for the predator to focus on one individual. If you have ever tried to catch an individual sheep out of a flock, you know that you really need to stay focused on one individual in order to be successful. Statistically, a sheep in a flock of twelve is less likely to be eaten than a sheep in a flock of three. So sticking together, circling, and following each other are not caused by stupidity. In fact, they show a sophisticated understanding of statistics!

What about when sheep scatter and run the wrong way? Every animal has a “personal space bubble” or “flight zone”. When you step into their flight zone, they move away. The size of the flight zone varies. The biggest factor affecting the size of the flight zone is habituation—how used to you the animals are. To reduce the size of the flight zone, habituate your sheep to your presence. They are intelligent enough that if you walk through their paddock regularly they will recognize you and become gradually less wary of you. If you step into their flight zone behind their shoulder, they will move forwards, in front of their shoulder they will stop or turn around. Always be aware of where you are in relation to the animal. Why does one sheep spin around and run away from the flock when you go to shut the gate? She is motivated to be close to the other sheep until you step into her flight zone, then she is highly motivated to gap it. So take your time, let them all move into the pen, then watch the outside sheep and move into her flight zone behind her shoulder as you slowly shut the gate.

There are between breed and within breed variations in the size of the flight zone. There are no naturally “bad” breeds though—animals of any breed will habituate with regular calm handling. Animals that are stressed or in pain will have a larger flight zone. You should keep this in mind and not expect them to react the same way they normally do when something is wrong. Sheep in a smaller group will be more reactive than sheep in a larger group. They type of stimulus will also affect the size of the flight zone. The most effective stimulus for getting sheep to move is something that is novel—something that they haven’t been exposed to before. It doesn’t need to be especially loud or annoying, even a plastic bag on the end of a stick works well until they get used to it.

If animals get really stressed, it takes them a period of time to go back to behaving normally. Think about the last time you had a near miss in traffic, and how long it took for your heart rate to go back to normal! So if things really turn to custard, walk away and let them relax and come back 20-30 minutes later (providing it is safe to do so).

Unlike dogs, sheep predominantly use vision to experience their environment. Sheep do see differently than we do. They see things moving on the horizon better than we do, but large things close-up not as well. They see greens and yellows better than we do, but reds and blues not as well (so don’t use them to help you chose your wallpaper). They see vertical bars on a gate better than horizontal ones—if your sheep keep banging into the gate maybe they don’t see it well.

You can tell it’s a Perendale because of the short little ears and because it’s on the wrong side of the fence

When you are designing handling facilities for sheep and cattle, whether it is a set of pens and races or just a couple of gates in the corner of the paddock, use these principles to make it easy for the animals to do what you want them to do. Set it up so that they can circle and stay close together. Make sure they can see where they are going; for example, make sure that you are not running a race into a blank wall. When you are moving animals, use their flight zone and balance point. Don’t chase them around in circles—you will only make them stressed. Habituate them to a handling facility by running them into it a couple of times before you do anything stressful or painful to them in there. Look through a race from the sheep or cow’s eye level to try and spot anything likely to make them baulk as they run through. Sudden changes from light to dark, shadows, reflections, and hanging flappy things are common issues that we might not notice that make sheep or cattle not want to run.

Why is this important? Firstly, if you are set up to use the animal’s natural behaviours instead of working against them you will get the job done more quickly. Secondly, you will get the job done more safely. People can get injured by sheep and cattle, and if you are stressed because you aren’t well set up to handle animals you are more likely to do something dangerous like roll the motorbike or tell your partner you don’t like their cooking. Thirdly, stress makes animals more likely to get diseases. So if you are set up to work with the animal’s natural behaviour instead of against it, you will find your animals are healthier, you are safer, the work is done more quickly and more easily, and you might find that actually sheep aren’t as stupid as you thought!

Keeping Your Flock Healthy

in 2016/Grow Organic/Livestock/Spring 2016
Small Flock Chickens, Poultry

Caitlin Dorward, Caroline Chiu & Kent Mullinix (Institute for Sustainable Food Systems, Kwantlen Polytechnic University) and Clayton Botkin (BC Ministry of Agriculture)

BC’s Fraser Valley is recognized as a major centre for commercial and supply-managed poultry production including layers, broilers, and turkeys. Also prevalent in this area is a small-scale poultry sector; the BC Ministry of Agriculture estimates that there are as many as 10,000 small flocks in the Fraser Valley alone. Many are “backyard” flocks kept for personal egg production or for direct-market egg sales from the farm gate. Some are kept by poultry fanciers dedicated to breeding and showing. No longer solely a rural pursuit, small backyard flocks are now allowed (subject to bylaw stipulations such as lot size) in many BC municipalities including Victoria, Kelowna, Kamloops, Vancouver, City of North Vancouver, Delta, Port Coquitlam, Surrey, and Maple Ridge.

Although the Fraser Valley’s 10,000 small flocks, at an individual level, account for few birds compared to the numbers kept in commercial operations, they play an important role in the local food system – and their small scale does not exempt them from the same poultry health and biosecurity concerns faced by the commercial sector. During the highly pathogenic avian influenza (HPAI) outbreak in December 2014, for example, the disease was detected in two backyard flocks.

Recognizing that small lot poultry producers also benefit from training in biosecurity and health management best practices, the Ministry of Agriculture and the Institute for Sustainable Food Systems (Kwantlen Polytechnic University—KPU) recently partnered to host a four-part “Keeping Your Flock Healthy” course at KPU’s Langley campus. This free course held over four two-hour sessions was intended for owners of small flocks looking to learn more about poultry diseases and ways to prevent them. Course instructors included Clayton Botkin (Industry Specialist, Poultry and Regulated Marketing, BC Ministry of Agriculture) and Dr. Victoria Bowes (Avian Pathologist, BC Animal Health Centre, BC Ministry of Agriculture), both North American experts in their fields. Dr. Daniel Schwartz (Canadian Food Inspection Agency) was also a guest presenter.

Those who attended came from across Metro Vancouver and the Fraser Valley and were small flock poultry owners who kept chicken as a hobby, for business, or for home consumption. Attendees expressed interest in learning more about disease management, general flock health, required lab tests, application of organic practices, protection against predators, information sources, licensing, scaling up, and industry regulations.

Considerations in Caring for Your Small Flock

Food Safety

From a food safety perspective, the food-borne illness salmonella is one of the biggest concerns for egg producers of all scales. Currently, testing of eggs for direct-market sale is not required, but of course providing safe, healthy eggs is a goal for all small-scale farmers, and testing for Salmonella should be a consideration. As such, small-scale egg producers should be aware of the risks posed by salmonella and how to mitigate them. For example, cracked or soiled eggs including those laid outside of the nesting box should never be sold or consumed. Egg candling and proper egg washing routines should also be implemented.

Chicks & Fertile Eggs

When it comes to small flock health, the source of chicks or fertile eggs is an important starting point. Small lot producers should take time to get to know any hatchery or other source from which their chicks are purchased. Ask questions about the hatchery’s quality control program, salmonella monitoring, vaccinations, health programs and accountability process. Before choosing breeds for your flocks, do some research about what breeds are appropriate for your area’s climate and for the purpose of your operation (e.g., egg production, meat production, etc.).

Small Flock Housing

The session included an introduction to poultry production and small flock housing. Newcomers to small flocks were able to take advantage of an introduction to poultry production and small flock housing. If you have a small flock, it’s important to seek out the regulations pertaining to small flocks and direct marketing of eggs, including the supply management or “quota” system – and learn about keeping your flock, premises, and product healthy.

Poultry housing is also a critical factor for small flock health. As a rule of thumb, remember that proper housing for your birds is just as important to their health as your own home is to yours! A simple checklist that can be used to evaluating the quality of poultry housing for all breeds is: Feed, Litter, Air, Water, Sanitation, and Security (FLAWSS). Use this checklist as a starting point but also familiarize yourself with any specific needs or housing requirements of the breeds in your flock to ensure you can provide them.

Diagnosing Disease

According to Dr. Bowes, a basic understanding of poultry anatomy (parts) and physiology (purpose/ function) can help small and large flock owners diag- nose, or at the very least notice, potential health prob- lems in their flock so that they can be addressed on site or brought to the attention of your veterinarian. The most common poultry diseases can be caused by viruses, bacteria, and parasites, and include avian in- uenza, E. coli, and mites.

4 Strategies that Prevent Disease

Strategies to limit the spread of disease are another important aspect of small flock management. Small flock owners need to conduct a critical examination of the premises where their flock is kept in order to identify potential points of pathogen entry. Once you have identified these points, you can develop and implement strategies to minimize the chance that disease causing organisms will gain entrance. In general, developing such a biosecurity protocol entails the following steps:

  • Access management: reduce the risk of pathogens being carried into and out of the flock premises
  • Health management: ensure that the flock is in good health, from chick to slaughter
  • Operational management: assure all procedures of your operation enable management of the health and well being of the ock and premise; barn area is always clean
  • Know and understand the procedures: be up to date with any issues and ensure that everyone involved with managing the flock and premise know the procedures for proper management.

The workshop concluded with information about techniques for humane euthanasia and plenty of time for questions from participants to the workshop instructors.

A small poultry flock can be the perfect business model, or a great way to produce your own food. No matter your goal, understanding how to promote the health and wellness of your flock is in your best interest, as well as the birds!

Integrating Livestock into Farm Rotations

in Grow Organic/Land Stewardship/Livestock/Tools & Techniques/Winter 2016
Raising Livestock, Pig

Corine Singfield

A Perspective on Pigs and Chickens

I could not imagine farming without the help of animals again.

As a young urban farming city slicker, I longed to homestead somewhere in the woods far away. I moved to the Great Bear Rainforest to start a new farm. We had no money to buy a tractor. As it turns out, a small rototiller is not a suitable tool to break down a freshly de-stumped and compressed forest floor. In his milestone book The Self-Sufficient Life and How to Live It, John Seymour writes “experience shows that for bringing grassland into cultivation either the plough, or the pig’s snout, is essential.”

An enthusiastic neighbour with pigs who had jokingly put out a “Hog for Rent” sign on his barn was coaxed into lending us five of his pigs for the task of turning the field into seedable earth. After two months of intensive rotational grazing, the pigs had cleared 1.5 acres and turned it into the basis of our market garden. They pulverized the quack grass and their powerful snouts tore through cottonwood roots.

We learned that it is critical to run some tests as to determine the perfect size of the rotational moving pen and the optimum time between moves. Leave them for too long and they will dig craters; not enough time and they will not have turned enough dirt. If the area is too big they will get picky with where they are rooting so a smaller pen ensures a more uniform job. We ended up splitting the 1.5 acre area into eight zones, moving them every week.

Many things come into play when making that decision: size and number of pigs, palatability of the ground cover, quality of the soil and the quantity of feed that you are giving them. Some farmers insert grains in a deep hole on the side of stumps. Pigs will go to great lengths loosening the soil in an attempt to retrieve the golden sweet oats.

Animals are central to operating a small closed loop farm where nutrients are produced and cycled on site to a level that does not exceed the carrying capacity of soil and thus prevents leaching into water sources. It is a cycle on which all food that we grow depends and it is a system that has fed humans for generations.

When managed properly, livestock can save farmers endless amounts of time by simplifying tasks like weed management, soil preparation, disease control, and post-harvest cleanup while being true portable composting machines.

After our success clearing the land with pigs, it felt like a natural next step to introduce pigs and chickens into our crop rotations. We started using the pigs to clean up after a potato harvest to ensure that there weren’t any volunteers carrying disease or insects for the following year. The pigs fertilize and till the soil making it ready for broadcasting a winter cover crop. A pig rotation can be used to break down and integrate plant biomass into the soil without compaction.

Harnessing the power of the pig’s snout or the scratching of chicken feet reduces the need for using a tractor and helps to preserve the soil’s structure, tilth and food web.

Harnessing the power of the pig’s snout or the scratching of chicken feet reduces the need for using a tractor and helps to preserve the soil’s structure, tilth and food web. Chickens can be used to mow the orchard, doing away with the tedious job of weed whacking around each tree. They can also be sent in right after the pigs to control flies or other insects. Moving your livestock around the farm increases your farm’s total herd carrying capacity.

Planning for Livestock

In order to integrate animals into your crop rotations you will need to move them. Try to imagine pathways for the moves. While chickens can be moved quite easily from one end of the farm to another with the help of a coop on wheels, pigs are much more easily moved on their own hooves. It helps to include your animal rotations right into your farm plan. If you wanted to use your pigs to clean up and prep the soil after harvest you could plan for the crops to ripen in succession from one end to the other of the field and have your pigs follow that direction. Pigs are not compatible with permanent raised bed so if that is your method of choice, you will want to go with chickens or ducks that have a lesser impact.

You also need to allow for enough time between the presence of livestock and harvest. Organic standards call for four months between soil’s contact with raw manure and harvest. If crops that accumulate nitrates are to be grown, the raw manure must be applied at least four months before these crops are planted. Nitrate-accumulators include brassicas, leafy greens, beets, and chard; raw manure must be applied in moderate amounts and the soil must be warm and moist.

Other things to consider are the type of soil, compaction levels, future crop plans, and the nutritional value of the crop. The perfect timing for your soil management plan might not be the same as for the maturity of forage.

Your end goal will determine which forage you will plant for your livestock. If it is to make the soil cultivable, you can choose deep root crops such as turnips, Jerusalem artichokes, potatoes, or fodder beets. If controlling weeds is a priority then less palatable grasses are best to encourage livestock to go for the weeds instead. To boost fertility, go with a mix that contains legumes.

Livestock Basics: Keeping Your Animals Happy and Healthy

Raising animals presents challenges that multiply the laws of unpredictability in farming by a few fold. They don’t always stay where you want them to stay. They can get sick or get into trouble. An emergency with livestock will always take precedence over a critical task in the veggie garden. They can save you time or cost you a lot. Make sure that you have contingency plans.

Raising animals presents challenges that multiply the laws of unpredictability in farming by a few fold.

Water

Livestock need fresh water at all time. Pigs are especially talented at flipping or destroying their watering apparatus. We like to use a bath tub with reinforced sides but even then you’ll end up finding one pig laying in it enjoying the remaining inch of muddy water from time to time. You’ll need to transport their water with each move.

Feed

Animals that have access to pasture are less prone to diseases and have higher levels of omega-3 fatty acids in their meat, and more vitamin E than animals raised in confinement. They are also happy. A happy animal is one that gets to live according to its true nature: a pig loves rooting in fresh dirt, a chicken loves scratching and pecking.

Feed requirements depend on the animal. In the case of grain eating omnivores – poultry and hogs primarily – they will need unlimited access to a species specific, balanced ration that includes minerals. You can supplement the rations with pasture, crop residues, and weeds while keeping in mind that no one type of pasture will consist of a complete diet. Pigs are monogastric, meaning that they don’t derive protein from eating grass like ruminants. They can’t survive on a diet of grass and greenery and still need to be fed grains even if they are cleaning up the veggie patch after harvest.

Pigs are naturally attracted to higher protein crops such as clover, alfalfa or field peas. Planting a few acres of peas for them allows to cut feeding costs significantly. For every 4 kg of alternative feed (weeds, beets, potatoes, etc.) that you give your pigs, you can reduce their ration by a 1 kg. If you want your pigs and chickens to thoroughly mow or clean up an area that is less palatable you can temporarily reduce their ration to induce a feeding frenzy. We like to mix oats and field peas as forage for the pigs. For a quicker turn around we use a few dense buckwheat plantings in a row and send the animals more often.

Shelter, Fencing

You will become an expert in all things electric fence related. E-fences are extremely simple to use when done properly, but you have to make sure that they are clear of obstructions, such as vegetation that can “ground” the power and weaken your fence. An overlooked detail with an electric fence can cost you a crop at the hands of pigs or an attack by predators. Almost every morning we find new traces of a coyote visit around the chicken pen. The electric fence works very well…when connected correctly.

You will need a few moveable electric mesh fences, a deep cycle battery, a fence charger, and a power source such as a small solar panel. A sense of humor and the willingness to wrangle the odd escapee from time to time can also come in handy.

Light and durable pens must be transported everywhere. A chicken tractor is perfect for hens that return to their roost at night, so they  can be transported to a new location before they awaken the next day. We use a small and simple slanted roof shelter made of recycled materials for the pigs. It can be moved small distances with 2 people or lifted with the tractor. Pigs don’t have sweat glands and cannot cool themselves so they must always have access to moist soil and shade.

Learning and Growing with Livestock

At the Tsawwassen First Nation Farm School where I currently dabble in the joys of farming, we plan on acquiring two flocks of chickens, some ducks, and about 30 pigs next spring. We are very excited to conduct experiments using chickens to mow the orchard, determining stocking rates, suitable feeding regimens, and optimal pen size. Similar experiments will be conducted with the pigs. I look forward to streamlining and simplifying my work as a farmer with the integration of livestock. Tune in next year – I’ll be eager to report on what we have learned!

Promoting Productive Pastures

in Crop Production/Land Stewardship/Livestock/Tools & Techniques/Winter 2016
Well managed pastures

Andrea Lawseth, B.Sc., M.Sc., P.Ag. AEL Agroecological Consulting

Pasture management is one of the main challenges for organic livestock producers throughout the province. In the lower mainland and on Vancouver Island, we struggle with wet climates and waterlogged grazing areas, while in the interior of the province the hot and arid climate poses other challenges that can be equally difficult to manage. Despite these difficulties, there are some techniques and tricks that you can follow to maximize the pasture that you have available and utilize your land more effectively.

Rotational and Limited Grazing

In order to maintain sales and productivity, livestock producers want to have as many animals on their land as the land can support. Sometimes we increase the numbers too much, which can result in overgrazing of pastures. Overgrazing occurs when 50% or more of the grass plant is grazed all at once. This can completely stop root growth and severely reduce grass production. Table 1 shows how grazing can affect root growth of grasses.

As the saying goes, “build your fence horse high, pig tight, and bull strong.” Fencing for rotational and limited grazing is often the best tool for reducing grazing pressure and overgrazing on your pastures. Rotational grazing involves breaking larger pastures up into smaller sections and only grazing one section at a time to allow the others to regenerate. This encourages even grazing of pastures as well as many other benefits such as: increased amount and quality of forage, increased growth of desired grass species, reduced weeds, better parasite control, better manure distribution, and more frequent animal-human contact.

As the saying goes, “build your fence horse high, pig tight, and bull strong.”

If you decide to implement rotational grazing then it is best to start by dividing a large pasture in two and grazing each of these separately. You can then divide further later on. Ideally it is best to have 4 pastures that provide enough grazing for 7 to 10 days as this gives each pasture a rest for 3 to 5 weeks. To divide pastures you can use electric fencing or tape at a height of approximately 90 cm (3 feet) or chest height of your livestock. This is a relatively inexpensive method that has proven to be highly successful. It is important to remember that you will need to monitor pasture growth at different times of the year and rotate accordingly.

Limited grazing involves turning your animals out for limited periods of time (once or twice a day, before or after work, for a few hours at a time). More supplemental feeding will be required and grass height will need to be monitored, but it provides the same benefits as rotational grazing.

Pasture Renovation

Most pastures in BC are in need of some repair due to overgrazing, wet winters, alkaline or acidic soil types, or dry summers. Grass that is lacking density with 50% weed growth or more will need to be renovated to some degree. Management strategies could include a combination of improved pasture drainage, fertilizing, harrowing, liming, and re-seeding depending on budget constraints.

The first step in dealing with an overgrazed or mismanaged pasture is to evaluate what you have to work with. Find a good weed guide to help you identify which weeds exist on your property and take some samples of your pasture soils to send them to a lab for analysis. Your lab of choice will be able to guide you on their most desired sampling technique and will be able to determine the full composition of your soil and nutrient needs.

Improving drainage through the use of surface or subsurface methods such as French drain tiles can eliminate standing water and ideal conditions for weed growth. Aerating the soil will also help water to penetrate below surface soil layers. Additionally, fertilizing with well composted manure will greatly improve soil structure and drainage. Spreading a thin layer of compost will help soil to increase its water holding capacity and will provide a great medium for spreading grass seed. It is recommended to spread once in the spring and again in the fall. Furthermore, harrowing with either a chain harrow or a tractor will also help to improve drainage and break up any clumps of manure compost you have spread.

Liming is an excellent technique for areas with very acidic soil. Weeds such as buttercup (Ranunculus spp.) or field horsetail (Equisetum arvense) are good indicators of acidic soil as they are well-adapted to these conditions. Liming should be carried out in the spring and fall and more often if needed. Again, a soil test will help to determine the pH of your soil.

Finally, re-seeding with an appropriate seed mixture for your property will help to out-compete weeds and maintain good forage production. The key to choosing a mixture is diversity. The varying grass species in a mix will grow in their respective microclimates within your pastures, which will lead to lower vulnerability to disease and pest outbreaks. However, it is still important to tailor your grass mix to the type of soil on your property and the expected use of the pasture (i.e. grazing, sacrifice area, or hay).

Make sure you mention the topography of your pastures and soil characteristics (gained from a soil analysis) to your seed retailer so that they can help identify the right mix for you. The best time to broadcast overseed your pastures is in late September to early October after you have spread your manure compost. Seeding rates will vary with grass species so check with your retailer before seeding.

Before allowing livestock onto the pasture to graze you should allow newly seeded pasture grass to reach a height of 15 to 20 cm (6 to 8 in) and remove your animals when they have grazed the grass down to 8 to 10 cm (3 to 4 in). This will ensure that the grasses have enough food reserves to permit rapid re-growth. Re-growth can take up to 2 to 6 weeks, depending on the time of year, so it is important to keep animals off wet, overgrazed pastures. Wet pastures can also lead to health problems such as foot rot and parasite infestation.

Keeping pastures mowed to a uniform height of 3 inches will help to stimulate equal growth of your grass plants. This will also help to control perennial weeds that do not respond well to mechanical control methods.

Properly managing pastures generally requires a shift in thinking from viewing the crop as a way to feed the animals to viewing the animals as a way of managing the pasture. As a grass farmer, your main goal is to ensure that the grass on your pasture is healthy enough to outcompete the weeds. Through rotational grazing and prevention of overstocking pastures, you will create the right environment to allow your grass to thrive and the soil to remain healthy and productive.

Hani Grasser looks out over his sheep at Robson Valley Sheep Farm

Raising Sheep Demands Constant Vigilance

Not far from McBride, BC, nestled in the beautiful Robson Valley bottom land that frames the Fraser River, is a wilderness paradise known as the Robson Valley Sheep Farm. Owned and operated by Theres and Hani Gasser, the certified organic farm is dedicated to raising high quality meat sheep, who share the land with a few dozen Angus beef cows, a few riding horses and some poultry for home use. Like most paradises, the Robson Valley Sheep Farm’s idyllic appearance is the result of careful planning, good management, and lots of hard work.

The Swiss Family Robson

Hani and Theres, along with their three little children, came to BC from Switzerland in 1988. Hani was fresh out of a four-year training program from a Swiss agricultural college, which included two years of hands–on apprenticeship and two years of classroom study. Hani had taken extra courses in organic farming, and was eager to put his knowledge to work in his new country.

After spending their first four years in Canada managing a biodynamic beef operation near Chase, BC, in 1992 the Gassers were ready to take the leap into farming for themselves. They bought land in Chase and for the next 14 years they very successfully ran the well known certified organic Mountain Meadow Sheep Dairy, producing sheep milk cheeses and yogurt.

Then, in the fall of 2006, the Gasser took an even bigger leap: they moved north to McBride, onto 535 acres of beautifully forested wilderness in the Robson Valley. Situated on a big bend of the Fraser River, their new domain came complete with an oxbow lake, a full mile of river frontage and a large acreage of fertile wetland full of local and migrating birds, which the Gassers now maintain as a bird sanctuary.

What the property did not include was livable space for the Gassers. The farm hadn’t been occupied for over a quarter of a century, and Hani and Theres’ first project was to change the large equipment shop into a dual service timberframe home and shop. Using their own pine beetle killed timber, the couple spent several years doing all of the renovations themselves.

The sheep on the Robson Valley farm are a variety of mixed breeds, resulting in a robust and healthy herd that can tolerate the cold winters and thrive in the wilderness environment. The Gassers brought their original dairy herd north with them, and since then have crossed the sheep with breeds that can lamb out at one year old, successfully mother the first time with a single lamb and then mature into an ewe that gives twins, while living on grass and hay alone. The Robson Valley sheep do not receive any grain. The size of the flock each year varies from about 100 to 300 mother sheep depending on the amount of hay produced by the start of winterfeeding. The sheep live outdoors all year round except during lambing, when the ewes are moved close to the house into the lambing barns where they can be checked every three hours.

Lamb at Robson Valley Sheep Farm

Since sheep and parasites love each other, parasite prevention dictates the rotational grazing schedule for the Robson Valley flock. The Gassers are careful to rotate their sheep out of a pasture ahead of the parasites’ maturation cycle. This means moving the sheep every week, or at the very longest, before 14 days. Thanks to electric fencing, the paddocks are kept small enough so that the sheep can be moved easily.

This rotational grazing pattern mimics natural ruminant behaviour of grazing the valley bottoms in the spring and winter and moving up to fresh mountain pastures during summer and autumn.

The Gassers also practice multi-species grazing, keeping cows and horses in the pasture along with the sheep. Combined with regular haying, the practices help to prevent the sheep from grazing in the same paddock more than once a year.

Inevitably though, occasionally a parasite appears. Whenever the Gassers detect evidence of parasites in one of the sheep, they are quick to administer their custom-order herbal de-wormer. The de-wormer, developed by the Gassers themselves with assistance from the staff at Urban Spice in Vancouver, contains wormwood, fennel seed and gentian. The Gassers’ have now started growing their own wormwood to ensure a ready supply of this key ingredient.

A Machine-Free Farming Lifestyle

Since neither Hani nor Theres enjoy doing mechanical repairs, they have reduced their reliance on farming equipment down to haying and fencing machines. When the pastures are in need of reseeding with red and white clover, timothy and orchard grasses, the Gassers simply hand broadcast the seed into a pasture just before the sheep flock is moved in, and rely on the sheep to trample the seed into the earth.

Alternatively, in the summer they add seeds to the cattle salts and let the cows do the work of spreading them — with organic fertilizer included for free! While these methods are slower than working the soil with equipment, the Gassers find them simpler, much less expensive, and less work-intensive. Currently their biggest problem in pasture maintenance is the encroaching advance of hawkweed and foxtail barley. Hani and Theres would love to hear from other farmers with suggestions for combating these weeds.

Because sheep require a diet much higher in protein than beef cattle do, growing, growing high-quality hay is crucial to sheep herd health, Hani explains. This is partly due to the fact that a cow weans a calf when it only about half the weight of its mother and a ewe weaning twin lambs has to raise nearly double her own weight.

That need for protein can make sheep fussy eaters, and very talented at nibbling off all the leaves and discarding the rough stems of the hay. And that can lead to a lot of wastage, so the Gassers have solved the problem with winterfeed by allowing only their sheep into a pasture to feed on a new hay bale first. When the sheep have finished picking over the bale, the following day the cows are brought in to clean up the leftovers. This method leaves very little waste and helps keep the Gassers’ collies busy herding all winter long too.

Doggy Defenders

Because of intense predator pressures in this neck of the woods, very good livestock guard dogs are required to be on duty at all times. Two or three Akbash or Akbash-crossed dogs (preferably Comondor) live with the flock all year long. The dogs are with the flock 24/7 — except when a female is in a ‘standing heat’ and needs to be temporarily kenneled.

The critical trick to developing a excellent sheep guard is that between its 6th and 10th week of age, the puppy must bond with livestock.

Thanks to the watchfulness of their guard dogs the Gassers lose very few animals. In fact, in the last nine years they report they have lost only 5 ewes — to an attack by a pack of wolves. The secret to their success? According to the Gassers, the critical trick to developing a excellent sheep guard is that between its 6th and 10th week of age, the puppy must bond with livestock. And they’re careful not to make pets of the dogs. As Hani says, “A livestock guard dog has no business in your yard, in a kennel, or on your porch. And it should only be fed and receive affectionate petting when by the flock. We are the Alpha dog to our guard dog pack and they come when called.”

Where the Akbash specialize in guarding the sheep flock, the Gassers use Border Collies and one New Zealand Huntaway to herd the sheep from pasture to pasture. Theres and Hani love to train and work with their guard and herding dogs and occasionally sell puppies.
