Methods to extend the grazing season, including stockpiled perennial forages, use of annual forages, crop residues, and bales left in the field, have considerable economic and environmental benefits over traditional winter-feeding systems. Well managed systems reduce or eliminate labour, feed harvesting, transport and delivery, and manure handling. These systems also allow for flexibility in returning nutrients back to the land instead of concentrating animals in pens. However, the ability to implement a winter grazing system is dependent on a number of variables including water availability, snow conditions, provision of shelter, and forage use by wildlife.
As with all winter management scenarios, caution is required when managing calves, young cows, thin cows and cows with calves, as they require higher levels of energy and management than mature dry cows.
Numerous studies have demonstrated the economic and environmental benefits of extended grazing systems. Costs of production are reduced compared to more traditional winter feeding in confinement, along with benefits to the environment and agronomic performance due to improved soil fertility and forage yields. Barriers for adoption expressed by producers include too much snow, lack of a winter water source, cold weather, feed waste, animal welfare and animal performance, all potential risks which must be carefully monitored and managed.

Rejuvenation of a forage stand, whether hay or pasture, involves using one or a combination of methods to increase productivity with a shift towards higher yielding forage species that provide improved nutritive value for livestock.
The first step in deciding whether to rejuvenate a forage stand is comparing the potential productivity with the current status of the pasture or hayfield. This will help determine if, and what, improvements or management changes are needed.
A stand assessment starts with evaluation of the current plant population. What desirable plant species are present as compared to undesirable plants? Are there invasive species? Poisonous plants? Are there large areas of bare ground and evidence of erosion? Conducting a pasture or range health assessment is an important first step to identify best options for rejuvenation.

Canada’s National Beef Strategy has four goals that our industry aims to achieve by 2020. For the past year this column has explained how research is contributing to a 15% increase in carcass cut-out value (the Beef Demand pillar), a 15% improvement in production efficiency (Productivity), and a 7% reduction in cost disadvantages compared to Canada’s main competitors (Competitiveness). The fourth goal (Connectivity) is about improving communication within industry and with consumers, the public, government and partner industries. Research contributes science-based information to underpin fact-based communication, policy and regulation, as well as extension (also known as technology transfer) activities to translate research results into improved on-farm production and management practices.
Extension used to be a core mandate for governments and universities; they all had extension staff, held field days and published producer-focused bulletins. Some researchers are still active in extension, but most institutions have shifted their focus to scientific research and technology development. The private sector has filled the extension gap in spots, especially where there is a clear profit motive for the company or individual doing the extension. This often works best when there is a product to sell, like a nutritional supplement, vaccine, or electric fencer. It is more challenging for the private sector to justify extension when the product is a management practice that is hard for a company to charge for, needs to be highly customized to suit individual operations, or primarily benefits the customer. Examples include low-cost winter feeding, crossbreeding, rotational grazing, and low-stress handling. Private sector extension can also be difficult with practices that benefit the overall industry but might not directly or immediately profit any specific individual (e.g. some animal welfare practices, antimicrobial and environmental stewardship). The BCRC tries to fill those gaps. Continue reading
Cover crops, also referred to as polycrops or cocktail crops, are receiving a lot of media hype for their potential for grazing and claims related to reduced inputs and improved soil health. Jillian Bainard, PhD, has been studying cover crop parameters like productivity, soil health, grazing nutrition, and weed control, through her research at Agriculture and Agri-Food Canada in Swift Current, SK. “A lot of people are trying cover crops so we want to understand from a research perspective what’s happening, and whether we can pinpoint some of these benefits that have been suggested,” Bainard explained during a recent webinar presentation.
Cover crops can address many problems, however they require thought and planning to optimize their potential.
Producers often look to cover crops to improve productivity. Bainard’s research demonstrated that some cover crop mixes had greater production compared to single-species crops (ie. monocultures) even under stressful conditions. Different functional groups, such as cool-season grasses, warm-season grasses, legumes, or brassicas, also had a positive effect on production; as the number of groups in a mix increased, production did as well. Bainard did caution that extreme moisture fluctuations will impact plant growth accordingly and that real-world field variables may reduce productivity. For example, a cover crop mix may yield well on lowland areas yet perform poorly on uplands within the same field. “Not all mixtures will perform the same, and success will depend a lot on how well each crop does in a specific soil and environment,” Bainard added.

Forage legumes provide high yields, protein, and good animal performance while improving soil fertility by fixing nitrogen from the air. Alfalfa is the highest yielding and most widely-used legume but can cause bloat. Legumes like cicer milkvetch, sainfoin and birdsfoot trefoil do not cause bloat. As little as 25% sainfoin in a pasture can virtually eliminate the risk of bloat even if the other 75% is alfalfa.
The problem is that older sainfoin varieties don’t regrow as fast as alfalfa after grazing. Alfalfa’s aggressive nature allows it to outcompete sainfoin for sunlight, moisture and nutrients. Without careful grazing management, sainfoin can disappear from a pasture in a few years. This might be because plant breeders have traditionally selected new varieties for clipped forage yield under monoculture conditions. This doesn’t reflect the challenges sainfoin faces when grown with alfalfa and grazed.
Surya Acharya at AAFC Lethbridge has been breeding sainfoin that regrows more rapidly after grazing and persists longer in mixtures with alfalfa. New varieties (e.g. Mountainview and Glenview) have already been released, but there are more in the pipeline. An update on these ongoing efforts was published in 2017 (Performance of Mixed Alfalfa-Sainfoin Pastures and Grazing Steers in Western Canada, Professional Animal Scientist 33:472). Continue reading

Tame forages often outperform native species in head-to-head comparisons under optimal growing conditions. This may not be the case on “marginal land,” with its tougher environments, poorer soil, rougher topography, harsher climates, and precipitation extremes. Beef production is expected to rely more and more on marginal land, at least while returns from cash crops exceed those from cow-calf production.
Beef Cluster research led by Mike Schellenberg (Agriculture and Agri-Food Canada Swift Current), Eric Lamb (University of Saskatchewan) and a team of graduate students has been examining Western Canadian native plants since 2009. Some results from this study were published in 2018 (“Mixtures of native perennial forage species produce higher yields than monocultures in a long-term study”; Canadian Journal of Plant Science 98:633-647).

The secret — if it is a secret — to pasturing cattle on alfalfa is to follow a few simple management steps to reduce the risk of bloat, say producers from across the country, who for years claim good success by including the forage legume in pasture mixes.
Straight alfalfa stands can be managed quite well, but most producers today are favouring alfalfa/grass forage blends. They are very productive, produce excellent rates of gain on cattle, help to reduce the bloat risk, and also provide important biodiversity. Biodiversity benefits the cattle in providing a range of crops that mature at different times and can handle varying growing conditions, as well as biodiversity to benefit soil health.
The main “not to do” message is don’t turn somewhat hungry cattle into a pre-bloom high percentage stand of alfalfa and leave them to selectively graze the lush leaves. If there is a heavy dew or rain as well, it creates a perfect storm for bloat.
The key “to do” messages include making sure cattle move onto alfalfa pastures with a full gut and the forage stand is dry. Introduce them to lusher forage gradually by limiting the amount of area they have access to in a day, and force them to eat the whole plant including stems and not just leaves. Other “to do” strategies that some producers use — supply a bloat-control agent in cattle drinking water, make some dry hay available as well, as the fibre in hay reduces the risk of gas build up in the rumen, and include low-bloat forage legumes such as sainfoin in the pasture mix.
It is important to apply some basic management principles to capitalize on the benefits of having alfalfa in a grazing program. As grazing research summarized in Part 1 has confirmed over the years, not including alfalfa in pasture mixes can be like leaving money on the table.
Here is what producers from across the country had to say about how alfalfa is managed in their grazing programs: Continue reading
High protein forage can increase rates of gain, benefit soil
Editor’s note: The following is part 1 of a two-part series. Stay tuned for alfalfa grazing tips from cattle producers from across the country in part 2.
Respect it, but don’t fear it. That’s the message from cattle producers and beef specialists alike who through years of experience and research appreciate the value of grazing cattle on pure or percentage stands of alfalfa.
Properly managed alfalfa makes good pasture with several added benefits, including:
- Improved weight gains on all classes of cattle (gains of 1.5 to 2 or more pounds per day can be expected);
- adding fertility to the soil with a nitrogen-fixing crop;
- creating a hedge against poor forage production during dryer growing seasons; and
- increasing plant biodiversity to benefit soil health.
Yes, there are circumstances when turning cattle into a lush stand of alfalfa at the wrong time and perhaps with the wrong class of cattle can result in bloat. But paying attention to a few production and management principles can greatly reduce the risk of bloat and provide producers the opportunity to capture the benefits. Continue reading
