Causes and risk factors of abortion in cattle

Vet Advice with Dr. Ron Clarke

By
When examining abortion in cattle, it’s important to look at incidence, cause, definition, when to summon help and what to do. As an aid to producers, abortion can be defined as terminating pregnancy any time after around 42 days, when placentation is complete. Placentation is the establishment of membranes joining mother and fetal blood supply […] Read more

Comparing feed performance in pregnant cows

Research on the Record with Reynold Bergen

By
Last month’s column featured a University of Saskatchewan research trial that used high-moisture corn grain, snaplage or silage to partially replace barley grain or silage in finishing diets. While the steers were in the feedlot, this team wintered cows on the corn stover. See: Performance and ruminal fermentation of second-trimester pregnant beef cows fed short-season […] Read more

Feeding cows for fertility

The right vitamin and mineral package, and high-quality forage, can boost a herd’s conception rate

By
The year is 1993 and Graeme Finn is saying goodbye to the blue skies and heat of Australia, replacing them with the gentle hills and crisp winters of Madden, Alta. Here, he starts a beef operation with his wife, Heather and their two daughters. With 2,800 acres of pasture rented, Finn is passionate about using […] Read more
Pay attention to what the cows can tell you — they’re likely all carrying worms, but the ones that have a high body condition score probably aren’t carrying as many worms.

When the worms come marching in

Research on the Record with Reynold Bergen

By
Gastrointestinal parasites are an unavoidable fact of life. Cattle often consume parasitic worm larvae along with the forage they graze. The larvae take up residence in different parts of the digestive system, develop into adults and lay eggs. The eggs are deposited in the feces, where they hatch and release larvae. These larvae eventually leave […] Read more

Feeding the pregnant beef cow

Nutrition with John McKinnon

By
In my previous column, I discussed how pregnant beef cows prioritize nutrient use for different physiological functions, including maintenance, lactation, pregnancy and growth. For those of you in Western Canada who were feeding cows during the last half of December 2021, you know full well how the cow’s maintenance requirements increase during extremely cold weather.

Prioritizing nutrient use in pregnant and lactating cows

Nutrition with John McKinnon

By
As we head into the new year, many of you will be thinking about calving and the upcoming breeding season. From a nutrition perspective, this involves planning a feeding program that accounts for the needs of pregnancy and lactation. It is well established that cows that lose condition in the last trimester of pregnancy will […] Read more
If a heavily pregnant cow has prolapsed, your veterinarian should have a clear idea when she is due to calve.

A vaginal prolapse is not just a prolapse!

Once diagnosed, it’s critical to treat the medical cause as well as the prolapse

By
This article will focus on only vaginal prolapses. The act of replacing these is the visible part but there are many other aspects veterinarians consider when working on these conditions. The cause, method of replacement, long-term care and expected force of straining afterwards must all be considered when vaginal prolapses are being corrected. As an […] Read more

Cold and abomasal impaction

Vet Advice with Dr. Ron Clarke

By
Beef cattle on the Canadian Prairies are subject to considerable environmental stress during winter. Starting with the early days of ranching and arrival of U.S. cattle onto the eastern slopes of the Rockies through the mid-1800s, survival of the beef cow meant adaptation to prolonged cold temperatures. Cold and the groundless belief that cattle could […] Read more

Tips on when and how to check that very pregnant cow

Calving Management: Dr. Cody Creelman goes over the three stages of labour

By
Most cows and heifers progress normally through the three stages of labour (early labour, active labour with abdominal straining, expulsion of the placenta after delivery of the calf). Uterine contractions in early labour get the calf aimed toward the birth canal, the cervix dilates and the calf starts through. The water sac and then the […] Read more

The economics of preg-checking

Research: News Roundup from the October 2017 issue of Canadian Cattlemen

By
The major economic benefit of preg-checking is the money saved by not wintering open cows. However, it has been noted that preg-checking is not always worthwhile, as the increased revenue due to higher prices for cows in the spring and the additional weights put on in the winter could more than offset winter feeding costs.
