Applications for the 2019-20 term of the BCRC Beef Researcher Mentorship Program are now being accepted. The deadline to apply is May 1, 2019.
Four researchers were selected to participate in the program this past year. Each was paired with two mentors – an innovative producer and another industry expert – for a one year term (ending July 31, 2019). Each of the researchers have reported very successful and valuable experiences through the opportunities provided, including:

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).
Editor’s note: Relevant and up-to-date information that had been available on Foragebeef.ca is gradually being added to BeefResearch.ca. (More information). The new Stored Forages page, which is previewed below, is one example. Further webpages will be added or updated on BeefResearch.ca to include the valuable content from Foragebeef.ca, ensuring that information remains freely available online. Completion is expected by Spring 2020.
Feed is the major input cost in cattle production, therefore producers must evaluate the cost of production for all stored forage systems.
The objective of harvesting any type of forage for storage is to preserve resources produced in the summer months in order to provide winter feed for livestock when grazing is not feasible or accessible. It is essential to harvest forage at the appropriate time, based upon nutritional quality, forage yield and climatic conditions, and then to store it properly to reduce losses.
Stage of plant maturity at cutting is the most important factor influencing hay quality. Young, vegetative forage is higher in protein and energy than older, flowering material. As forages mature, stem is increased in the total forage mass and the leaf-to-stem ratio is reduced. As a result, fibre increases while protein and digestibility decreases. Continue reading

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
