Calving Records Will Be Especially Valuable This Year

Last month’s column profiled a beef cow productivity study that coincided with the massive 2001-02 drought that impacted most of Western Canada. That study got less attention than it deserved, because Canada’s entire beef industry became preoccupied with BSE in 2003. But research is an investment, and the lessons learned from research done two decades ago are still paying dividends today. This month’s column focuses on what that study learned about reproductive performance.

What They Did:

Dr. Cheryl Waldner and her colleagues from the Western College of Veterinary Medicine examined factors affecting the productivity of over 30,000 beef cows in more than 200 well-managed herds across Alberta, Saskatchewan and the Peace Region of B.C. Participating producers individually identified each cow and calf, recorded all calf births, 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. These results have been published in Theriogenology 79:1083-1094, Theriogenology 81:840-848 and Livestock Science 163:126-139.

What They Learned:

This spring’s calving records can help identify cows that are less likely to rebreed successfully or more likely to have problems next spring. Continue reading

7 Tips to Remember This Calving Season

Calving can be an exciting but challenging time. Luckily, there are some key actions you can take to set yourself — and your calves — up for success. Whether you are in the middle of calving season, or planning for the next, the BCRC has several helpful calving resources.

Here are seven tips to remember this calving season:

1. Do not hang calves upside down if they need help breathing.
Never hang calves upside down if they need help breathing
If a newborn calf requires resuscitation, put them in the calf recovery position, poke a clean straw in their nose, dribble a few drops of water in their ear or rub them vigorously. Hanging calves upside down actually makes it more difficult for the calf to start breathing. Fluid that drains from a calf that is hung upside down mostly comes from the stomach, not the lungs, and gravity will make it more difficult for the lungs to expand.
