Is This a Good Investment?

The Beef Cattle Research Council (BCRC) projects featured in this column are funded by the Canadian Beef Cattle Check-Off. When the checkoff increased a few years ago, the BCRC’s budget rose from around 15 cents to 67 cents per head marketed. This allowed us to start some new research programs. Now that we’re a few years in I can update you on how they’re going.

One is our “Proof of Concept” program. Research is complicated and costly, so we have independent scientists review each research proposal to make sure it is scientifically sound and likely to achieve its goal before investing your dollars into it. Sometimes the reviewers say, “This is an interesting project, but it’s really costly, and it all hinges on an untested idea. It’d be better if they had some preliminary evidence that this new idea is worth pursuing, before funding a costly, full-scale project.”

In 2018 the BCRC started funding Proof of Concept projects to gather these preliminary results and help decide whether these new ideas are worth scaling up into full-scale research trials. Here’s what two of the first Proof of Concept projects told us.
intercropping corn and high-protein forages for better beef cattle nutrition
Exploring corn intercropping strategies to increase protein and profitability of beef cattle grazing:
Corn’s high yields and energy content make it a popular wintering grazing crop for some Western Canadian producers. However, it’s low protein content may make it unsuitable for younger, growing cattle. Seeding corn together with high protein forages may be a way around this challenge.

Everything Old is New Again – Treating Chronic Mycoplasma

This article written by Dr. Reynold Bergen, BCRC Science Director, originally appeared in the October 2020 issue of Canadian Cattlemen magazine and is reprinted on the BCRC Blog with permission of the publisher.

Cattle were ideally created (or evolved) to consume and digest high fiber diets. Whoever (or whatever) was responsible for designing the rumen so elegantly probably should have paid more attention to the respiratory tract.

The design of the bovine respiratory tract makes it easy for BRD bacteria like Mannheimia, Pasteurella, Histophilus and Mycoplasma to move deep into the lung and find places to hide and makes it hard for the animal’s immune system to counterattack them. The bovine lung is so susceptible to infection and damage that it has been used as an “animal model” of chronic obstructive pulmonary disease (COPD) in humans.

This is a problem because cattle need a lot of oxygen. Cattle need nearly three times as much oxygen as a similar-sized horse just to stay awake and lie around. But the horse has nearly three times more lung capacity than the steer. Lung damage is one of the reasons that BRD hits cattle so hard, so fast. Continue reading
