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 Grazing Management webpage, 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.
Effective grazing management on pastures not only ensures high forage yield, sustainability, animal health and productivity, all of which impact cost of production, it also benefits the pasture ecosystem. Innovations in pasture management give producers greater control to support the environment (e.g. biodiversity) but also allow them to better use pasture resources for food production.
Pasture is a critical resource in the cattle industry. An effective management plan requires clear understanding of forage production, realistic production goals, effective grazing strategies and timely response to forage availability and environmental changes. Managing grazing lands so that they are productive and persist over time requires knowing when to graze certain species, if they can withstand multiple grazings/cuttings within a single year and how much recovery time is needed to prevent overgrazing.

Cattle that consume forages with higher sugar content have higher rates of gain, improved performance and better rumen health.
In a past BCRC webinar, Gilles Bélanger, PhD, a Research Scientist at Agriculture and Agri-Food Canada and Robert Berthiaume, PhD, a dairy production expert in forage systems at Valacta, offered the following tips for producers to increase the sugar content in their forages:
Cut forages in late afternoon
As the day progresses, the plant increases in sugar content and is at its highest levels between 11 and 13 hours after sunrise (late afternoon). This benefit is maintained after cutting. Although swathing reduces the sugar content, it will remain higher in forages that were cut in late afternoon as compared to those cut in the morning. Learn more from the webinar recording: 9:05 -19:56.)
Choose forage species with naturally higher sugar concentrations
In addition to management Continue reading
Rangeland, or range, can perform a number of valuable functions for both the livestock industry as well the general public. Rangeland is defined as land that supports indigenous or introduced vegetation that is either grazed or has the potential to be grazed and is managed as a natural ecosystem. By evaluating its health, cattle producers can manage their grazing lands for optimal, sustainable forage production.
The benefits of maintaining healthy rangeland for livestock producers include:
- Lower feed costs
- Renewable and reliable source of forage production
- Stability of forage production during drought
- Greater flexibility and efficiency for alternate grazing seasons (fall or winter)
- Lower maintenance costs like weed control
- Does not require the input of inorganic fertilizers and other soil amedments and additives
- Reduced concern for noxious weeds
In the previous episode of the Beef Research School, Dr. Paul Jefferson explained how to maximize your forage acres, including when to rejuvenate and when to reseed. In this episode, we take a closer look at rejuvenation methods.
Dr. Bart Lardner with the Western Beef Development Centre discusses why producers should consider fertilizing hay and pasture land. In addition to chemical fertilizer or composted manure, in-field winter feeding systems are another strategy to consider. Continue reading

Soil is like a bank account. If the nutrient withdrawals are always larger and more frequent than the deposits, the land bank will eventually go broke.
Plants use nutrients from the soil (and carbon dioxide from the air) to grow roots, stems and leaves. Some plant nutrients get returned to the soil through decomposition, manure and urine, but a lot of them don’t. Cows use the nutrients to produce milk and rebreed, and calves turn the nutrients into weaning weight. Over time, a lot of soil nutrients leave the pasture and go through the auction ring at fall feeder sales. If nutrients aren’t returned to the pasture through fertilizer, pasture productivity will eventually drop, and more forage acres are needed to raise the same number of cattle.
Alfalfa and other legumes help restore soil nitrogen, increase forage yields and extend pasture carrying capacity. The risk of bloat when grazing pure alfalfa stands can be reduced through Continue reading
