“The eye of the shepherd fattens the lambs”
By Dale Engstrom, MSc, Pag
I think I do a pretty good job interpreting feed and water reports, developing specifications for commercial feeds and balancing rations for my clients. During my farm visits, I look the feed and flock over closely and make recommendations for possible improvements. However, I am only on the farm 2–4 times per year, so I rely on feedback from the shepherd to put the feeding program into practice, and make it work and be profitable. Successful shepherds have good powers of observation and keep good records. The combination provides me with the information I need to evaluate the feeding program I have put together.
Here are the production records that relate to sound nutrition of the flock:
- Body condition score (BCS). BCS is a direct result of the energy levels of your rations. Protein and other nutrient deficiencies can negatively impact the amount of energy extracted from the feed. Learn and use the BCS system and record the results of at least a representative sample (10–20%) of the flock every time they are run through the handling system.
- Birth weight of lambs. Singles will be heavier than twins or triplets, Suffolk lambs will weigh more than Dorset lambs, but you should develop an average weight for your biological type that tells you if everything has gone well in the last 6 weeks of pregnancy. If the average birth weight drops noticeably one year, look at the energy and protein levels in your late pregnancy ration and the body condition score of your ewes. Some prolific flock owners have a minimum threshold birth weight they use to cull lambs that are not likely to thrive or survive.
- Abortions and stillborn lambs. These losses are most likely related to disease, but severe vitamin and trace mineral deficiencies may be involved.
- Pre-weaning mortality. Pre-weaning deaths can be caused by a variety of disease and management factors, but when trying to determine the problem and the actions to be taken, don’t ignore nutrition, especially those nutrients related to a healthy immune system.
- Weaning weight. Weaning weight is largely a function of milk production in the ewe, which is heavily impacted by nutrition before and after lambing. Ewes need to be in a BCS of 3–3.5 at lambing to have the potential to milk well. They can access some needed energy from body fat to support lactation, but they need adequate dietary protein and other nutrients to maximize milk yield.
- Days to market or average daily gain. Post-weaning growth rate in lambs is obviously impacted by nutrition, but genetics is also a large component.
- Pregnancy rate. Fertility is a function of body condition, ram power and length of breeding season. Nutrition impacts the rate through both the ewe and the ram.
- Prolificacy. The number of lambs born per ewe is a function of biological type and nutrition. Aim for a BCS of 3- 3.5 at breeding to maximize the number lambs born. Ewes below 3.0 will benefit from flushing for 2 to 4 weeks prior to breeding.
Two final points:
Did you notice how many times body condition score was mentioned? This is one of the best indicators of a good nutrition program and one of the easiest to do. Learn this technique and practice it often. Here are the annual targets for BCS:
- Breeding Ewes: 3–3.5
- Breeding Rams: 3.5
- Lambing Ewes: 3–3.5
- Ewes at end of Lactation: 2.5
I have avoided providing hard numbers for the indicators listed above because there are large differences between breeds and individual operations. You need to develop meaningful targets that are suitable to your sheep and farm resources with maximum profitability as the goal. But where do you start? The GenOvis genetic evaluation program provides annual reports based on the information they get from participants. This data is from purebred flocks that are typically smaller in size than many commercial flocks, but it provides valuable data nonetheless. The table on the opposite page will give you some indication of what is normal for some of the measures.
The ‘eye’ of the shepherd, also known as good stockmanship, has long been recognized as a valuable tool in the profitable production of lambs. Today we know the eye is really a variety of tools and measurements that can be used to provide an objective analysis of the production program, and several of them are very specific to the nutrition part of the management system.

Breezy Ridge Farm was established in 1983, when Phil and Liz Smith bought a 32-acre parcel of land and established a small flock of 40 mixed breed ewes. In 1990, they acquired their first purebred Rideau Arcotts, shortly after the release of the breed from the Agricultural Research Centre near Ottawa. The flock has since grown to 550 head, with seven different genetic lines. As the flock has expanded, so has the land base; in 1999, the Smiths were able to purchase 65 acres on the other side of the road, which had at one time been part of the same farm. They also rent a further 155 acres of hay land.
Like many Rideau flocks, the Breezy Ridge ewes are managed to lamb more often than once per year. Phil describes the size of each lambing group as fluid, because it evolves with conception rates and changes in the management system.
Breezy Ridge ewes grazing alfalfa pastures. Lasolocid is added to the free-choice salt and mineral mix to reduce bloat.
All of the ewes lamb in the first half of the year, either in March/April or May/June/July. The March/April group is exposed to rams again in June. Those that conceive and lamb in November are weaned and rebred (along with the ewe lambs) starting at the end of December to become the late lambing group the following year. The May/June/July group gets rebred starting November 1, to become the early lambing group the following year.
The June breeding season takes place on pasture, with all of the early-lambing ewes being exposed together in a single group to multiple rams. Some of these ewes are treated with CIDRs, but a number of the ones that do not receive CIDRs also conceive and go on to lamb in November. Ewes exposed in June get scanned in October to determine if they are pregnant or not, but the operator doesn’t attempt to count lambs, as Phil feeds all pregnant ewes as if they are carrying triplets. Ewes that are not pregnant at scanning get rebred in November and lamb in March and April again the following year.
Round bales of hay and silage are fed in a bale feeder designed by the Smiths to reduce lamb losses.
Phil limits the June and November breeding seasons to a single, 21-day cycle to allow for time off between winter lambing groups so that barn spaces can clear out between groups of lambing ewes and the family can recharge their own batteries (and go curling).
Above, and below: Corn and pellets are hand fed in a grain-feeding yard in lightweight feeders made from lengths of 18” plastic culvert. Some of the feeders are mounted in frames to keep the sheep out and permit panels to be attached on either side.
The original barn on the home farm was torn down in 1986 and replaced with a metal-clad, pole barn measuring 40×80’ that is now used primarily as the lamb feedlot. A 30×100’, greenhouse-type structure and a second metal-clad pole barn (104×44’) provide housing for ewes and space for lambing. There are two hoop buildings for hay storage (100×30’ and 68×30’) in the yard, and a further 50×104’ of hay storage on the 65 acres across the road.
Ewes that lamb in the fall and winter do so in the barn. Lambs are tagged and recorded while in the lambing jugs, and given Baycox® to prevent coccidiosis at 24 hours of age. Mature ewes get to keep three or four of the lambs they give birth to, depending on their past performance and milk supply. Additional lambs are reared on Serval Lamb-O milk replacer on a Förster-Technik milk replacer machine in the insulated, 11×30’ nursery barn. All lambs (except those raised on pasture) are creep fed on Distiller’s Dried Grains with Solubles (DDGs). Lambs raised on ewes are weaned at 60 days; lambs on milk replacer are weaned at 28 days or 25-30 pounds.
Ewe lambs are housed and fed separately from the mature ewes until they are a few weeks away from lambing, when they join the May/June lambing ewes. Weather permitting, the whole group goes out on pasture in mid to late April, where they give birth. After a couple of days in a lambing jug in an emptied hay shed, ewe lambs with one lamb, and mature ewes with one or two, stay outside and raise their lambs on pasture. Ewe lambs with twins, and mature ewes with three or more, go from the jugs into group pens inside the barn.
When I spoke with the Smiths in late August, all of the ewes had been weaned and were being pastured in a single group, and Phil was looking forward to his third cut of hay being harvested in the next two weeks. With 550 ewes to feed, the entire land base is devoted to grazing and forage production, with grain and supplements all being purchased.
The 32 acres of the home place is almost always in pasture, unless it is being renovated. The Smiths have been strip-grazing silage corn since 2006. They plant it the year before the alfalfa is reseeded, and graze it or bale it as silage. This year they have about five acres in corn, although they have had as many as 15 after a bad winter kill on the alfalfa. A 36-acre parcel of rented land right next door is also used for pasture in late summer and fall; the ewes run down the road every morning and back every evening. Previously used as hay land, this piece is a bit worn out, but Phil is waiting to ensure he will have ongoing access to it before reseeding it.
Extra lambs are raised on a milk replacer machine in an insulated, heated lamb nursery building. Sons David (left) and Nicholas are both home and working on the farm right now.
The Smiths’ own land is fenced with five strands of electric wire on the perimeter and three strands inside, most of which is Gallagher. The 36-acre piece next door is grazed with portable reels of electric fence with two wires and step-in posts, another Gallagher product, which is powered from the permanent fence at the boundary with their own land. The reel/wire combination is also used to subdivide pastures for rotational grazing.
The remaining 65 acres of owned land, and 119 acres of rented land, are used for hay production. All of the hay fields are at least 80% alfalfa, with the balance of the mix in orchardgrass and timothy. Hay fields are replanted with brown midrib sorghum sudangrass as a nurse crop. The sudangrass produces a good volume of forage, but the bales have to be wrapped in plastic. A custom operator puts up the hay, with the Smiths doing the raking and bringing the bales in from the field.
After the frost in the fall, the ewes graze the 65 acres of hay land across the road from the home place, where some of them also get bred. Last fall, the snow came on November 1 and they missed out on that late fall grazing.
The ewes are supplemented with purchased corn grain and a 34% crude protein supplement pellet, with the amounts fed depending on the stage of production. Lambs raised on ewes are fed a mix of corn and the same pellet. The pellet also includes the vitamins and minerals required by the ewes and lambs. A custom salt and mineral mix provides extra selenium to the pregnant ewes, so that lambs do not have to be injected with selenium in the claiming pens. The custom mix is also used when the ewes are on pasture, as it contains lasalocid (Bovatec®), which helps prevent bloat on the alfalfa pastures.
Above and below: Drop down augers in both steel barns allow for easy expansion of the lamb feedlot as needed. Repurposed hog feeders work well for lambs and can be raised up on a tire as the lambs grow.
Ewe lambs that are selected for breeding stock are taken off concentrates and introduced to pasture at 75 pounds. Ram lambs are selected and put out with the mature rams at 110 pounds. Lambs raised on pasture are weaned at 70 days of age and transitioned onto full feed in the barn.
All of the lambs get an RFID tag at birth, which is used as a management tool, not just for traceability purposes after they leave the farm. A Psion handheld computer scans the tags on the ewes and lambs in the jugs and records this and other lambing data, which is uploaded to the Ewe Byte Management System on their home computer. Weighing data are collected by a Tru-Test XRP2 Electronic ID reader and XR500 scale head and also uploaded to Ewe Byte. Phil makes extensive use of Ewe Byte to manage the flock and track the level of inbreeding among its seven different genetic lines. Data is also exported to GenOvis, the national genetic evaluation program, which produces EPDs for maternal, growth and carcass traits, allowing the Smiths to compare their animals to Rideau Arcotts in other flocks across Canada.
Because the ewes that lamb in November are exposed to multiple sires, all flock replacements are chosen from lambs born at other times of year. Ram lambs are selected from dams that are at least five years old, based on the dam’s performance for number of lambs weaned, adjusted 50-day weights and lambing intervals, a very time-consuming process. Ewe lambs are selected on similar criteria but because more of them are needed, they can be selected from ewes that are less than five years old.
Most of the ewes have three or more lambs. This ewe has five and will be allowed to keep three or four of them, depending on her past history and milk production.
After being selected as lambs, based on the longevity and performance of their dams, rams get tested as yearlings for genetic resistance to scrapie and Maedi visna. Liz says the genotype information provides another level of selection information that some buyers are looking for, after first selections are made on performance.
Like most producers who pasture their sheep, the Smiths spend more time thinking about worms than they want to and are interested in solutions that go beyond consideration of available worming products. Since 2011, they have been involved in a breeding project aimed at developing parasite resistance in the Rideau Arcott breed. They have partnered in this with Dr. Angela Canovas of the Centre for the Genetic Improvement of Livestock at the University of Guelph, and Delma Kennedy with the Ontario Ministry of Agriculture, Food and Rural Affairs.
Hired man Justin Pape drenches lambs with assistance from David Smith.
The selection is based on regular fecal samples, and Phil is very enthusiastic about the progress they have made in selecting resistant animals (see sidebar page 14). DNA samples have also been taken from the whole flock for future testing for genetic markers for parasite resistance.
Although they do a brisk business in breeding stock, the Smiths also sell slaughter lambs. Because of their location one hour from Toronto, they have lots of marketing options, but most go to the Ontario Stockyards at Cookstown at about 100 pounds live weight. With lambs born over several months of the year, they are able to ship lambs nearly year-round.
Phil and Liz are fortunate to have their sons, David and Nicholas, working with them on the farm, as well as a hired man, Justin Pape, who works Monday to Friday but puts in longer hours during lambing. Phil, David and Justin do most of the feeding, lambing and record keeping; Phil is also in charge of promotion. Liz does the book-keeping, provides late evening lambing help, and starts new lambs on the milk replacer machine. Nicholas is recently back in the country after volunteering for two-and-a-half years at the Baháʼí World Centre in Haifa, Israel. With his work as an electrician disrupted by the pandemic, he has been spending more time on the farm.
Students prepare to collect fecal samples from a group of rams as part of an ongoing project to select for resistance to parasites.
After nearly 40 years of raising sheep, Phil and Liz seem keen to continue, and even expand the flock to support the involvement of one or both of their sons. Expansion will depend on their ability to secure more land in the area and put up additional buildings to accommodate more ewes. The work on selecting a parasite-resistant Rideau Arcott is especially rewarding, as it complements their belief in grazing their animals and taking a holistic approach to sheep farming.

Suffolk ewes and lambs on pasture at Blackie Farm, Florenceville, New Brunswick.
By Cathy Gallivan, PhD; Photos by James Blackie
Blackie Farm is located in the village of Florenceville in western New Brunswick, which is less than 15 km from the US border. This area is known for growing potatoes, and the village is home to the corporate headquarters of McCain Foods, the largest producer of French fries in the world.
The 200-acre farm was purchased in 1926 by James’ grandfather, Daniel Blackie. Daniel had three sons and two of them, including James’ father, went off to fight in the Second World War. The remaining son, James’ Uncle Donald, stayed home and ran the farm after Daniel died in 1940. The farm is long and narrow and climbs upward from the eastern bank of the Saint John River. James says there have been sheep on the farm as long as it has been in his family.
The farm was purchased by James’ grandfather in 1926.
James grew up within a mile of the farm and spent most of his free time there, especially in the summers. His uncle raised potatoes and had a commercial flock that peaked at around 275 ewes in the early 1970’s. James remembers seeing his first lamb born when he was 10, and shearing his first sheep, a North Country Cheviot, at 12.
James graduated from high school in 1973 and went to the Nova Scotia Agricultural College in Truro. There he met Cecile, a French Acadian girl from St Charles, on the eastern side of the province, and brought her to visit the farm the following summer. Uncle Donald was not exactly progressive in his thinking, being of the opinion that a woman’s place was in the home rather than out working with the animals. But while they were out on the pasture looking at the sheep, they needed to catch one for some reason and Cecile proved her mettle by grabbing it by a hind leg and not letting go. Uncle Donald didn’t say much, but never questioned Cecile working with the sheep again.
One of three breeding groups being bred on pasture in October.
James finished his Bachelor’s degree in Animal Science at Macdonald College of McGill University in 1977 and he and Cecile were married the same year and began living in Truro. Cecile worked at the college there as a Chemistry Lab Technologist, and James sold feed for Shur-Gain.
In March of 1980, James got a job working for the New Brunswick Department of Agriculture in Wicklow, just across the river from his uncle’s farm. He and Cecile returned to Florenceville and built their own house on the farm. The next 10 years were a busy time. James helped his uncle on the farm and worked full time, while Cecile kept busy with the five children born to them during those years.

Uncle Donald died in 1994. It took a while for things to be settled but James and Cecile were able to buy the farm from his father and remaining uncle in 1998. James had always had sheep of his own within his uncle’s flock. After his uncle’s death these became the foundation of their own commercial flock, which peaked at around 100 ewes in the 1990’s.
The flock was managed traditionally. Lambs were born in March and pastured throughout the summer. Most were slaughtered at a small, local abattoir and delivered to freezer customers. The ‘tail-enders’ were put on a truck and sent to an auction in Quebec. James put up his own hay and fed it along with whole oats in the winter, the quantity of each depending on the quality of the hay. When the hay was poor, he fed more of it and allowed the sheep to pick through it and select the best parts.
Above and below: Lambs are born in March and go to pasture in May with the ewes, but still have access to creep feed in the barn until 100-day weights are taken in early July, after which they are weaned and pastured separately from the ewes.
Over the last 10 or 12 years, the purebred flock has gradually replaced the commercial ewes and today there are only registered Suffolks on the farm. The ewes still lamb in March; James says he and Cecile are too old to change their ways, and at least when the temperature falls to -30 Celsius in March they know April is just around the corner.
The feeding regime is also largely the same, consisting of their own hay supplemented by whole oats. Although his uncle grew potatoes on the farm, James found putting up around 3,500 small, square bales of hay and managing the sheep on pasture took as much time as he could spare from his full time job when he was working. He buys whole oats and an 18% crude protein creep ration with added Bovatec (for coccidiosis control), as well as second-cut hay for the creep feeder. Straw is purchased in the field from another farmer and James bales and hauls home about 700 small, square bales each year.
Pregnant mature ewes last winter. This picture was taken to taunt a fellow Suffolk breeder who roots for the Maple Leafs.
Since purchasing the purebred sheep, and especially since his retirement, James has increased his investment in the flock to improve its health status and performance. After several years of testing for genetic resistance to scrapie, all but one of the ewes are now AARRRR (resistant). Last fall the entire flock, including the lambs, were tested for Maedi-Visna and all of them came back negative. James plans to continue testing and hopes the flock will receive its “A” status on the Ontario Maedi-Visna Flock Status Program in the next year or two.
The flock is also registered on the GenOvis genetic evaluation program. Lambs are weighed at 50 and 100 days of age, and for the past six years a technician has come from Quebec to ultrasound them for fat and muscle depth. This allows James to select on the CARC (carcass) index when choosing rams and ewes for his flock, and also to provide that information to prospective buyers. The GenOvis report on pages 10-11 shows the 2019 production of the flock. The 2019 Lamb Report (21 pages, not shown) provides index results for each of the 83 lambs that were ultrasounded. The emphasis on the CARC index is noticeable: 14 of the 83 lambs are in the 99th percentile for the CARC index, and a further 15 are in the 98th percentile.
James participates in the All Canada Classic when the location and timing of the event allow, and his animals have been well received by buyers at the sale. But he prioritizes the production of a good terminal sire for the commercial producers he primarily sells to over success in the show ring.
James regrets not having bought an effective handling system many years ago and finds the digital scale much faster and easier to read than his old spring scale.
One of the biggest challenges the Blackies have had to deal with over the years is parasitism. The barber pole worm is as big a problem here in western New Brunswick as it is in the rest of the country. They have also had problems with liver flukes, which they didn’t realize until they were alerted to it by the abattoir where their lambs are processed. The current protocol is to treat the ewes at lambing with Valbazen, and then worm both the ewes and lambs throughout the summer with Startect, starting three or four weeks after they go to pasture.
Coyotes are another potentially serious problem when pasturing ewes and lambs, but the Blackies have had good luck keeping them out with a combination of electric fencing and Nite Guards. The perimeter fence consists of 12.5-gauge wire. Temporary fences made from a lighter wire (17-gauge) subdivide the pasture into 1-acre paddocks for rotational grazing. The Nite Guards are solar-powered lights that flash red from dusk to dawn. The combination of electric fencing and the Nite Guards seems to be working and the sheep have been able to stay out at night in their paddocks for the last 10 years.
James and Cecile Blackie
Among the many lessons learned over 40 years of raising sheep, James includes:
Make sure you spend the extra to get the ewes in great shape for breeding and for the winter, otherwise you are trying to catch up all winter. One tonne of grain costs as much as one lamb at most.
The single most important management item when pasturing sheep is to worm them and then know that the wormer is working, and to keep on top of your worming schedule; otherwise, a lot of effort is going down the drain.
Don’t put off getting a sheep handling system. If you decide to get one, spend the money to get a digital scale. The numbers are harder to make a mistake on, especially when your eyes aren’t as young as they used to be.
In addition to the sheep, James and Cecile have another farm enterprise, a market garden, which started in the early 90’s with their three sons at the end of the lane selling a barrel of potatoes. By 1995, they were selling more vegetables from the front of Uncle Donald’s old house, which was still standing in the yard. The enterprise has grown over the last 25 years and now 10 acres of the farm is dedicated to the vegetables, and a new market stand sits where the old house used to be. Crop residues are not a problem; the sheep happily consume the pea and bean vines, corn stalks and any vegetables that are not good enough to sell.
The farm climbs gradually from the river to the back, where there is a beautiful view in all directions. Corn and other vegetables are planted early under plastic. The fertilizer plant seen on the right is on the opposite side of the river.
James and Cecile grow everything in the market garden, but are perhaps best known for their Awesome corn, which many local residents look forward to sampling as early as the August long weekend. Green peas are another big seller, and Cecile has a machine that will shell the peas for her customers after they are purchased.
Because the farm is located right in the village and right next to the McCain Foods plant and headquarters, Cecile is able to sell most of the vegetables right out of their yard, although she does attend a weekly farmers’ market in the nearby village of Bristol. A walk-in cooler in the market stand allows them to store and sell crops such as winter squash later in the season than before. One significant worry about the vegetable business is the way the sheep eye the peas, corn and other vegetables on their way out to the pasture, something that keeps James awake at night, wondering if he shut the gate.
With the onset of the COVID-19 pandemic this spring, the Blackies thought about whether to plant vegetables this year or not. They decided to go ahead, knowing that they would have to make major changes in how they deal with the public to sell their produce.
James and Cecile work hard and make a good team. James says, “The sheep are an island where we tend to agree most of the time. I do the chores and Cecile does most of the paperwork. She is the midwife for any lambing problems we might have, and the one with the patience to get a stubborn Suffolk lamb to start sucking. She also helps with communication when French-speaking producers give us a call. I don’t really know what they say but it seems to work out.”
James told all of their children that if they didn’t go to university they might end up back on the farm with him. All five have university degrees and none are back yet. He credits Cecile for motivating them to further their education.
Cecile attends a weekly market in nearby Bristol. All of the Blackie’s signage proclaims ‘We grow everything we sell!”
James and Cecile don’t know how many more years they’ll raise sheep or grow vegetables. James prefers the sheep, but acknowledges that the vegetables involve less physical wear and tear (on him). He jokes, “I tell everyone that when I climb up into the haymow every morning and night, all I have to do is miss one rung and I might be into early retirement.”

It was a cool, cloudy January afternoon when I pulled into the parking area at Willowdale Sheep & Lamb, 10 minutes south of Steinbach, Manitoba. The farm sits on a ¼-section (160 acres) that is part of a larger operation owned by Apex Farms.
Harry Warkentin is the manager of the facility, and even before I met up with him I knew I was in for an enjoyable afternoon. As I stepped out of the truck I could hear the voices of the staff hard at work but clearly enjoying what they were doing—always a good sign in any operation. We started our visit in the farm office/staff room over a cup of coffee. From here you can keep an eye on the sheep through a system of cameras strategically placed throughout the barns.

The Willowdale barns are close to home for Harry and his wife, Lorna. They live on the ¼-section straight north of the sheep barns and used to own this one as well. This new venture has been up and running for just over two years, and is currently home to 1,800 ewes.
Like many sheep folks, the Warkentins have a long history in agriculture. They ran a dairy for 12 years and then moved to hogs, putting up the buildings that are now filled with sheep back in 1988. They got into sheep in 2011, and their flock grew to 400 head as they transitioned out of hogs. That flock was merged into what is now the Willowdale flock.
The Warkentins sold this quarter, with the hog barns, three years ago. The new owners wanted to diversify their livestock operations, and asked Harry and Lorna to develop and manage a new sheep operation for them.

The flock is mostly straight-bred Rideau Arcotts; there is also a small group of Canadians. The flock is divided into 12 breeding groups of 150 head each. Rams go in with the first group in mid-August, and more rams are added to new groups every two weeks until mid-January. Most (94%) of the ewes catch in the first cycle after being exposed to rams; the rest lamb later with the later breeding groups.
The Willowdale ewes lamb just once a year, but some of them do it out of season in October. Harry uses CIDRs on the ewes that are exposed for fall lambing. Last spring (2019), there were 250 ewes synchronised and exposed to rams, and 75% of them lambed last October.
More out-of-season lambings are planned for this fall, in September, October and November. Harry plans to move into accelerated lambing in 2020, by putting CIDRs in some ewes that lambed this winter, as soon as their lambs are weaned.
The ewes are grouped using a 4-colour tagging system and bred to unrelated groups of purebred Rideau Arcott rams, sourced from Phil and Liz Smith in Ontario. Harry looks for rams with good performance information but is also interested in the work the Smiths are doing with breeding for parasite resistance.
They currently have six ram groups, each with six rams, which are also colour-coded, making for an easy visual tracking system that prevents inbreeding. Lots of ram power is one of the keys to their successful breeding program.
Lambing rates run from 2.3–2.4 in the fall-lambing ewes, and around 3.0 for ewes lambing in season, for an overall rate of about 2.6. The flock is fairly young and these numbers are expected to increase as they mature. The target is to retain or market 2.2 of the 2.6 lambs dropped, and Harry looks forward to higher numbers as they move towards accelerated lambing.

The original barn built for the hogs needed significant internal changes to adapt it for sheep. Pits were filled and all of the floors leveled with an additional layer of concrete. A local welding firm built the panels for pens, alleyways, and gates. The barn is nearly 30,000 square feet in area and consists of five interconnected sections. The lambing area is the largest and is broken up into drop pens that hold 25 ewes. The end of this section contains 39 lambing jugs and several nursery pens.

Once the lambs are born and bonded, groups of ewes and lambs move to one of three indoor pens, each of which will house 150 ewes and their lambs, where they stay until weaning. These pens are fed using an automated conveyer belt that delivers a TMR twice daily to a central feed trough built to provide a foot of feeding space per ewe. Each pen includes a creep feeder for the lambs where they can access a custom, 18% crude protein crumble. Straw is used for bedding throughout the barns.

The fifth section of the barn contains the handling system and the shearing area. Garrick Reimer, a local shearer, comes in every two weeks from January to June as ewes approach lambing. There is an on-site hydraulic wool packer and full wool bags are shipped to Canadian Cooperative Wool Growers.

Directly west of the barn, there are 12 newly built, outdoor paddocks with open-sided shelters that are 12 feet deep. Each paddock is 150 feet long by 70 feet deep. The fence line feeders run the length of the paddock with a 22-foot paved and sloped alleyway between the pens. The pavement extends 7 feet into the pens, giving the sheep solid footing at the feeders in wet weather.
The pens are 150’ long by 70’ wide; sheds running the length of the pens are 12’ deep. Photo by Dale Engstrom.

Ewes in these pens are fed a TMR that is mixed and fed every second day. On alternate days, a blade is used to push the remaining feed back up against the feeders, a very efficient system. The ewes stay outside until a week before lambing, when they are brought into the barn and shorn, wormed, vaccinated with Glanvac 6, and treated with Vetolice.
Harry will tell you that a comprehensive nutrition program is essential. The bulk of the ewe ration is a mix of bagged corn silage and alfalfa haylage. The farmland adjacent to the barns has been seeded to alfalfa and the corn silage is harvested from nearby rented land. Barley and corn DDGS (dried distillers grains with solubles) supplement the energy and protein provided by the forage.
Dale Engstrom, a livestock nutritionist from Alberta, visits the farm twice a year and balances rations for ewes in each stage of production. Every new bag of hay silage is tested, and the TMR rations are tweaked accordingly.
Custom premixes, designed by Dale and made up by the New Rosedale Feedmill in Portage la Prairie, are added to the TMR to provide salt, mineral and vitamins for ewes in different stages of production. Selenium has been added to address the natural shortage of this trace mineral in our prairie soils. There is a ‘Dry’ ewe premix, which is fed to ewes in maintenance, but also to those being flushed and bred, and to those in early pregnancy. The ‘Lactating’ ewe premix has higher levels of vitamins ADE, as well as Bovatec for the prevention of coccidia, and is fed to ewes in the last six weeks of pregnancy and the first 6-8 weeks of lactation. Limestone is occasionally used to increase calcium content of the TMR. Having all of the required minerals and vitamins in the premix means fewer injections for newborn lambs and less work for the staff at lambing time.
Lambs are weighed, tagged and docked at birth, and also injected with ¼ cc of Tasvax and a ½ cc of penicillin. They are tagged with both a CSIP tag and a breeding group tag in the appropriate colour. Lambing information is recorded on the Shearwell FarmWorks program. Ewes and lambs get up to three days in the claiming pens, if there’s not too much lambing pressure. Ewes are left with two lambs and extra lambs are moved into nursery pens of about 15 head. These pens are all connected to a single Förster-Technik milk machine. A second machine, a Lak-Tek II, is kept at the Warkentin’s farm, where the lambs go to be grown out and finished after weaning. This allows for older nursery lambs to be moved over to the finishing yard if the regular nursery gets too crowded. The target for weaning nursery lambs is 30 days or 10 kg.
Lambs raised by the ewes are weaned at 8 weeks of age and taken on a short trailer ride to the Warkentin’s home yard for growing out and finishing. The original hog barn and adjacent hoop structure on this property are separated into several pens and feed is delivered through augers directly into self-feeders. The 16% crude protein ration is a mix of whole barley and a 32% custom crumble. The variable speed auger from the crumble bin allows the ration to be adjusted as needed. The lambs are vaccinated again shortly after weaning, ewe lambs with Glanvac 6 and male lambs with Tasvax.

Most of the finished lambs (60%) are marketed to SunGold Specialty Meats in Innisfail, Alberta, and the rest are sold through lamb buyers like Ian Deans of Newdale, Manitoba. Harry is keen to chase the market, saying, “If you don’t do it right, you’ll leave money on the table.”

Lambs sent to SunGold have a live weight target of 125 lb., which they reach at 5–6 months of age. An on-farm spreadsheet has been developed to calculate when lambs will meet this weight and help plan the shipping dates. It includes a number of variables including average daily gain, the percentage shrink on the trip to Alberta, and the historic carcass yield. All of this is done to optimize market returns based on SunGold’s preferred carcass weight of 26.7 kg. The lambs get weighed frequently, which is made easier with an electronic scale and Psion tag reader. The scale does not have Bluetooth capacity (yet), meaning that someone has to read the weight off the electronic scale and type it into a handheld computer/tag reader (Psion) as the lambs are weighed, but at least no one has to read eartags and no clipboard is required.
Harry keeps an eye on the square footage allocated for each lamb as pens are filled. With several people working in the operation, prominently posted written instructions make sure nothing gets missed. Photo by Dale Engstrom.
With the flock in expansion mode in recent years, Harry has been retaining most of their ewe lambs. Now that they are at capacity, he plans to start marketing replacements to other farms. Harry looks for ewe lambs from dams with a history of multiple births and good growth rates. He doesn’t keep replacements out of ewe lambs, preferring the proven performance of more experienced ewes. Ewes that can’t, or won’t, raise their lambs are culled along with their female offspring.
Although most of the focus of Willowdale Lamb is on the barn and outdoor pens, there is a grazing element to the operation. Apex Farms has a hog operation just outside the nearby town of Niverville, and part of the ewe flock grazes the 60 acres surrounding those barns. Another 60 acres of rotational grazing is available on the Warkentin quarter. Four livestock guard dogs accompany the ewes in the summer and keep coyotes at bay. Predation has not been a problem so far. Ewes get wormed when they come in off the pasture.
Even with all of the automation on the farm, lambing 1,800 ewes and keeping them and their lambs fed is a big job. Harry has two full-time and 2-4 part time (depending on the season) staff working with him. These employees handle the day-to-day work of feeding the stock, moving the ewes and lambs through pens, and processing lambs in the jugs.
A number of Manitoba hog barns have been repurposed into sheep barns over the last few decades as the hog industry here has consolidated. Harry and Lorna’s expertise has made the Willowdale operation into one of the best examples of how to do this. The buildings are comfortable, bright and well ventilated. The interior is smartly laid out, and the penning well made and more than adequate for the job. The outdoor pens are well designed for our prairie climate and provide a very efficient feed delivery setup.
As Harry and I discussed the operation, it was clear to me that the Warkentin’s experience in both the dairy and hog industries have added a lot to their understanding of how to make a sheep operation run efficiently.
