Bovine respiratory disease (BRD) is one of the costliest health issues facing the beef industry today. While a lot of research on BRD has been focused at the feedlot stage, the disease is also the most common cause of death for nursing calves older than three weeks. BRD can impact any producer, including those who retain ownership of their calves to background, feed, or finish cattle.
Research by USDA ARS Meat Animal Research Center that tracked the annual incidence of BRD in pre-weaned calves over a 20-year period found that the annual incidence varied from a low of 3% to a high of 24% with an overall annual average of 11%. On average, the mortality rate of calves suffering from pre-weaning BRD was 13%.
Several large studies have linked BRD to seasonal peaks. Nebraska researchers collected several years of data on 110,000 calves and found two seasonal peaks in the incidence of BRD. One peak occurs from birth through around 20 days of age, and another takes place when calves reach 70 to 100 days of age. Other studies have shown a similar pattern. The most common age group reported as having BRD were calves between one to 4 months of age.
Once calves are affected by BRD, there are both immediate and long-lasting effects on performance. Studies have shown that calves challenged by BRD could weigh up to 36 pounds less at weaning than their healthy herd mates (Wittum and Perino, 1995). Continue reading

I once spent a summer working for canola breeders. Some used traditional selection, while others were experimenting with transgenics. One traditionalist was known to say “sticking a new gene into a plant and expecting it to grow better is like throwing a new gear into a watch and expecting it to keep better time. It’ll probably get worse”. This article isn’t about canola or genetics, but it is about time and unintended consequences. Specifically, it’s about the timing of the breeding and calving seasons.
Canada’s cow-calf sector has moved towards fewer, larger beef cow herds. Calving later, on pasture has been a widely adopted strategy allowing producers to expand their cow herds without a proportional increase in equipment, labor, and facilities. When John Basarab led Alberta’s Cow-Calf Audits in the late 1980’s and late 90’s, breeding often started in May and calving started in late February. In contrast, 70% of the producers responding to the 2017 Western Canadian Cow-Calf Survey started breeding in June or July to calve in March or April.
Do you ever look at a feed analysis report and think “huh?” Unsure of how to collect and send away feed samples for testing? Want to be sure you’re using feed wisely so your cattle perform as expected without wasting valuable feed? This webinar is for you.

Calgary, AB – The Canadian Beef Advisors are pleased to release the 2020-24 National Beef Strategy. The strategy is designed to take advantage of the opportunities facing the industry while simultaneously addressing the challenges.
The development of the 2020-24 National Strategy has been a dynamic collaborative process engaging all industry sectors and national and provincial organizations. The Canadian Beef Advisors and provincial cattle associations believe a united industry is a stronger industry, and that a stronger industry benefits all those working in it today and into the future.
Substantial progress was made under the 2015-19 strategy and the intention is to continue building on the strengths of existing industry organizations. “The National Beef Strategy has provided real value for Canadian beef producers; it acts as a roadmap for the groups as they work together. We have set our industry up for success, now we just need to follow through.” said David Haywood-Farmer, Past Chair of the Beef Advisors. Continue reading
