Research that’s underway now won’t solve this year’s drought, but it should help us deal with the next one. By the same token, research done during the big drought of the early 2000s provides some valuable lessons about managing the cow herd in today’s drought.
Dr. Cheryl Waldner of the Western College of Veterinary Medicine in Saskatoon led a large beef cow productivity study from the start of the 2001 breeding season through weaning in 2002. This corresponded to the widespread drought that impacted much of Western North America and inspired the original Hay West program.
What They Did:
They 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 British Columbia. 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., not calve year-round), and worked with the research team to collect the needed samples and data.
What They Learned:
Drought had significant impacts, even in these well-managed herds. Continue reading
