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 Rejuvenation of Hay and Pasture 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.
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.

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
Cattle can be managed to produce calves, beef and milk, but can they also be put to work re-seeding pastures?
The palatable black seed pods of cicer milk vetch will no doubt be consumed by these yearlings on this fall-grazing pasture and distributed over other parts of this and other pastures. Most of the cicer milk vetch in this pasture was establish by cattle depositing seed through their manure. (Photo provided by Graeme Finn)
As long as you’re not in a hurry, producers who manage beef cows and yearlings so they distribute legume seeds through their manure, say “yes” it can be a passive, yet effective means of establishing desirable forages on pasture.
There doesn’t appear to be a handy term to describe this re-seeding technique, and on many farms and ranches with late season grazing it probably happens naturally anyway.
But several Alberta producers who see a benefit, are making a point to manage pastures so cattle are consuming mature forage seeds, in hopes at least some are shed in manure and germinate to establish the species on other parts of the pasture. And from their observations over the past few years, it works. Continue reading
