Vaccines Are Cheap Insurance – Don’t Let Your Premiums Lapse

After last summer’s pasture conditions and last winter’s feed costs, it’s safe to say that many cow-calf producers are facing the upcoming grazing season with some anxiety. Some are looking for new grazing arrangements, opportunities to trim input costs, or both. No single solution can solve every challenge for every operation, but nearly all decisions have trade-offs. Using a community pasture or other shared grazing arrangement may reduce pasture costs but mixing different herds can spread reproductive (and other) diseases. This risk is magnified if you’re tempted to save costs this year by skimping on your vaccination program.

The February and March editions of this column drew from a large beef cow productivity study that happened to coincide with the 2001-02 drought in Western Canada. That study also revealed how important vaccination programs are to maintaining reproductive performance. These results were published in Livestock Science 163:126-139 and Theriogenology 79:1083-1094; 81:840-848.

What They Did:

To recap, Dr. Cheryl Waldner and her colleagues from the Western College of Veterinary Medicine studied the productivity of over 30,000 beef cows in over 200 well-managed herds in Alberta, Saskatchewan and B.C. Participating producers individually identified each cow and calf, recorded all calf births (including abortions), maintained an active veterinary-client-patient relationship, had good animal handling facilities, pregnancy tested all breeding females, had a veterinarian evaluate all herd bulls, had an established spring or summer breeding season (i.e., didn’t calve year-round), and worked with the researchers to collect the needed samples and data.

As part of the study, they compared the pregnancy and abortion rates in these herds, based on whether they used community pastures and whether they vaccinated their cows against BVD and IBR before the breeding season. These two diseases don’t just affect calves; they can also reduce reproductive success in cows. Continue reading

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.
