Meet Bluestem Farms.

IMG_6098 (1024x683)

While in past years the Amelia County operation has been home to a herd of Kiko goats and several outstanding performance-tested bucks, Robie and Angie Robinson and their children have spent the past twelve years shifting their focus towards growing and improving their sheep and cattle herds.

IMG_6125 (1024x683)

Like many farmers, the Robinsons raise a little bit of everything to sustain their family—chickens, meat from their livestock, and a large garden with everything from asparagus to onions. While they also finish, harvest, and sell some meat to a group of local customers, they market most of their animals including their weaned feeder calves conventionally on the livestock market as most local cattlemen do.

However, their cowherd is rather unique—it consists primarily of Devons, not to be confused with Milking Devons which are also rare in this area. Devons are a hardy, red-coated breed from England and they come in the relatively small to moderate frame size that Robie maintains as a goal for his breeding program. He pays particular attention to the genetics of his herd through bull selection and culling. Because he relies on a forage-based production system, he wants cows that are programmed to efficiently convert grass to milk for their calves and he wants beef calves that grow well on a grass-based diet. Like the many other cow-calf operations in the region, most of the calves will be weaned and sold as “feeder calves” to buyers who will take them elsewhere for more growth and “finishing” prior to harvest. However, since Robie finishes some of his own animals on grass and harvests them for customers, he pays particular attention to carcass quality traits when he selects bulls for his program.

While driving past Bluestem, it is hard to miss the Robinsons’ herd of sheep. After all, relatively few people in Southside Virginia still raise sizable herds of sheep. Robie made the transition after he noticed more desirable marketing opportunities for his sheep than for his goats, and today he raises them primarily for the Easter market, a prime window for selling lambs.

Like his beef herd, Robie’s sheep are also unique. His ewes are mostly Katahdins, a breed of hair sheep that requires no shearing because the animals shed their coats in the spring. Katahdins have been recognized for their success on grass, high fertility, and adaptability to a variety of conditions, making them an excellent fit for the Robinsons and their forage-based grazing management program. While some breeds traditionally lamb indoors and require special care to ensure good mothering and survival immediately after lambing, Katahdins are well-suited for “pasture lambing,” and Robie notes that he rarely has to provide any assistance to his ewes at lambing time.

As with his cattle, he uses careful culling as a tool to reach towards his goals for herd genetics. Ewes that fail to produce and raise twins are generally removed in favor of ewes who are predisposed to prolific lambing and good mothering traits. He also culls in favor of sound feet and easy shedding. The Robinsons have managed to import desirable genetics into the herd via purchasing performance-tested rams from University of Maryland and Virginia Tech.

Sheep are notorious for wearing out pastures and cattle can be equally hard on forages if producers do not manage their grazing systems carefully. Since the Robinsons rely on grass to do all the legwork for growth and milk production for both species, they have prioritized pasture care on the operation to meet their needs. Robie has a few goats in every field with the sheep because they tend to graze onions and some of the other hard-to-control broadleaf weeds that sheep may pass over.

While he used to apply conventional fertilizer regularly, Robie’s philosophy on fertility management has shifted over the years and today he prefers to rely mostly on chicken litter when it is needed. However, when using litter, he notes that he must take care not to overload the field with certain nutrients, especially phosphorous. Like all farmers, he occasionally needs to lime his fields to adjust the soil pH. He manages his grazing strategy according to conditions—in some cases, he chooses to “flash graze” his fields to manage bouts of rapid spring top growth.

A visit to the Robinson farm yields a blue-green view of plentiful orchardgrass throughout the sheep pastures. Orchardgrass is a high-quality, highly-palatable species that also makes excellent hay. However, if it is mowed or grazed repeatedly close to the ground, it does not tend to persist. Robie uses a haybine instead of a disc mower when he cuts his fields for hay, and over the years he has seen that his orchardgrass has thrived and persisted for much longer than expected.

IMG_6094 (1024x683)

Mixed with the orchardgrass is some hairy vetch and plentiful clover, much of which turned up in the pasture on its own. Robie planted some stands of hybrid Bermuda grass experimentally in past years and those stands remain productive each summer. He has also planted Red River and Quick and Big crabgrass, both of which make excellent forage and seem to reseed themselves readily.

IMG_6064 (1024x683)

IMG_6068 (1024x684)

Bluestem has changed considerably over the past twelve years, as have Robie and Angie’s production strategies. Robie used to engage in row crop production before favoring livestock—the farm as it stands today was started with twelve registered angus cattle. Around the same time that Robie gained an interest in Devons and Katahdins, he also shifted his paradigm surrounding farm management in favor of grass ecology and robust soil microorganisms. “I was a cattleman, then I was a grass farmer, now I’m a mycologist,” he jokes. Nonetheless, his goals for building healthy land and soil are serious, and the proof is in the results—healthy lambs and calves, green pastures, and happy customers.

Meet Mike Henry, pasture manager.

100_1241 (1024x768)He has worn many hats over the years—Extension agent for Chesterfield County and then Amelia before he retired, cattle producer, and founding member of the regional Amelia Area Cattlemen. He is also one very excellent pasture manager. He spent the last several years improving the pasture on his Amelia farm, adding fencing and water sources as he went. When he first set out, his goal was to sustain enough forage to successfully support a beef cattle herd on a year-round strip-grazing management system.

100_1229 (1024x768)

Pasture land in central Virginia is abundant, hence the number of cows in the region, but not all producers are able to sustain animals year-round on pasture alone. Why? The availability of pasture forage depends on the seasonal growth of the species in the pasture. Because this region is set between the cold northern climate and the warmer South, cool-season and warm-season grasses can both be grown here and many pastures contain a mixture of both.

100_1233 (1020x1024)

Mike Henry’s pastures contain a mixture of tall fescue, orchardgrass, clover, and even some ryegrass that emerged in early winter.

Cool-season forages grow most actively in spring and fall when the weather is cool, but go dormant in the summer when little moisture is available. Many producers must resort to feeding hay during this season while they wait for fall pasture regrowth. Tall fescue is the most common cool-season forage in most pastures, but other plants like Kentucky bluegrass, orchardgrass, timothy, and clover are also in this group.  Cool-season grasses stop growing during the winter, but can be preserved or “stockpiled” during the cold. Tall fescue is the hands-down best choice for stockpiling, retaining its nutritional value for several months after the growing season even under snow and ice. In order to stockpile a tall-fescue pasture, the manager must remove the animals from the area in the late summer, giving the pasture a chance to recover and initiate heavy fall growth. The animals can return to the well-grown pasture in December or January, resulting in an extended grazing season that heavily cuts the costs associated with feeding hay.  Mike Henry practices stockpiling on his pastures, as do many of his peers in this region.

100_1236 (1024x768)

Warm-season forages like Bermuda grass or crabgrass have the opposite growth pattern. Their growth is dominant during the hottest part of the year, but they go dormant at the end of the summer and do not take off again until the spring. As a result, producers with pastures full of warm-season plants must either feed hay during the cool seasons or establish a cool-season pasture in a new area to keep cows fed during the fall, winter, and spring. 100_1232 (1024x768)

Mike Henry’s pastures contain mostly tall fescue, but other elements including crabgrass, orchardgrass, clover, and ryegrass are present and contribute to the diversity of the available forage. The clover mixed with the cool-season grasses is a legume plant, meaning that it contains a high level of protein and supports the needs of young, growing cattle and lactating brood cows. To establish and maintain dense stands of these forages and choke out competing weeds, Mike has stayed on top of mowing, seeding, reseeding, and nutrient management, but the economic benefits have outweighed the costs.

100_1227 (1024x768)In a “continuous grazing” system, cattle are given access to the entire pasture acreage at once, so they have the option to overgraze forages that are highly palatable, stressing the plants’ root systems. They under-utilize other areas, and they tend to create muddy spots near central hay feeders and water troughs. Finally, they may not distribute their manure very evenly, resulting in both mucky areas with a glut of nutrients and neglected areas that receive very little natural fertilizer. The alternative? Many producers have adopted “rotational grazing,” whereby a pasture is split into a few sections and animals are moved from one section to another every few days or weeks. As a result, each pasture section has an opportunity to rest and build strong roots, resulting in a longer-lasting, more robust stand of forage. Furthermore, the animals consume the existing grasses more evenly and efficiently. Manure is distributed far more uniformly in a rotational system, which aids in desirable nutrient cycling and reduces fertilizer expenses.

100_1238 (1024x768)

Mike Henry practices the more intensive cousin of rotational grazing, known as “strip grazing.” In this management system, cows are given a small strip of pasture at a time and are moved from one strip to the next as frequently as once a day or sometimes even every few hours. The pasture utilization rate increases dramatically when animals are tasked with eating one small area at a time. Mike knows that the key is making sure that the cows always have something to eat, so he will be the first to tell you that strip grazing brings an economic advantage but also a new requirement for labor.  Nonetheless, since most cattlemen check their herds frequently, the time it takes to open or close a temporary fence to a pasture strip is negligible and affords an opportunity for the producer to get a close-up look at the cows.

100_1230 (1024x768)Mike’s pasture setup is conservation-minded. He has excluded his cattle from the dam and waterways on his farm, and on the occasions when he has had to supplement his pasture with an occasional bale of hay, he unrolls and spreads the hay in a new area each time so that the cows do not heavily disturb the soil in one particular location. 

100_1239 (1024x768)

As a former Extension agent, Mike understands the value of helping other farmers, so he has had the opportunity to show his system to several beginning cattle producers and even a few experienced ones who wanted to see strip grazing in action. He has also noted one unexpected benefit from all his time spent moving fences and walking the pasture to check on his forages—the heifers he manages have become more docile from close daily exposure to his presence and follow him wherever he goes, making it easy for him to take them wherever he needs them. Add up quiet cattle, a thriving pasture, and annual hay savings to get one content cattleman.

Meet the Alexanders.

100_0774 (1024x768)

They operate Avery’s Branch Farms, a dairy, pork, and poultry operation in Amelia County. The Alexanders started their farm business about six years ago and moved to their current location in 2009. They are primarily milk producers who interact with local consumers via a cow shareholding system, but they also raise poultry and pigs in order to offer chicken, turkey, pork, and eggs for sale. The family has made it their goal to feed their milking herd a pasture-based diet and to build healthy soil that can sustain pasture plants. Tim, his wife Joy, and their children run the operation together.

100_0775 (1024x768) 100_0747 (1024x768)

The Avery’s Branch milking herd is composed of about fifty head of Jerseys and crossbred animals. Why Jerseys? This breed does not produce the same volume of milk per day as the Holstein does, but Jersey milk tends to be high in butterfat and protein and is excellent for making cheese. Jersey cattle also perform well in the outdoor conditions on grazing operations and are widely used in many parts of the country. 100_0753 - Copy (1024x768)

The milking herd relies primarily on forages to meet their needs. The cows receive a small amount of grain to meet their remaining nutritional requirements because lactating animals naturally require a high-energy diet in order to produce milk.

Like any grazing operation, Avery’s Branch strives to manage their pastures in such a way that forage is available for the majority of the year. Any farmer who runs out of pasture by the winter or faces a slump during a hot summer must resort to feeding hay, which can become costly. To reduce the number of hay-feeding days per year on the farm, Tim utilizes a diverse mix of annual and perennial forages in his pasture. Some of his pasture consists of tall fescue and clover, both of which are cool-season grasses that thrive in fall and spring and can be “stockpiled,” or saved up in the fall for grazing during the winter. The clover also “fixes” nitrogen from the air and adds it back into the soil, making it available for plants to use.  Since cool-season grasses typically do not grow well during the hottest months, Tim plants warm-season annuals such as sudangrass, sorghum-sudangrass, and crabgrass, all of which thrive during the summer months when cool-season grasses have gone dormant. Keeping crabgrass as a desirable pasture plant may come as a surprise to people who despise seeing it in their lawns and gardens, but crabgrass is actually a higher-quality forage than many of its warm-season counterparts and contains about 15% crude protein and 60% total digestible energy when it is grown in fertile soil.  The Alexanders have also planted winter annuals like ryegrass and oats to help get through the coming months.

Weeds, weather, and soil factors all play a role in the quality of the forages that are available to the cows. This year, wet weather has allowed cool-season forages like tall fescue to keep on growing all summer long. Weeds are also a concern on the farm, as they are for all producers, but the Alexanders combat them by clipping them to weaken them and rotating animals between pastures. Pasture rotation reduces the stress on desirable plants and allows them to recover quickly and choke out undesirable plants.

100_0786 (1024x768)The Alexanders have continued to grow their farm to further meet the needs of their customers and shareholders. Their willingness to try new practices and evaluate their successes and failures objectively has allowed them to take their farming operation from an idea to a real-life success.
