Ranchers talk turkey about purebred bulls

Two seedstock bull producers share how they develop marketable breeding males

There are many decisions which weigh into raising a saleable purebred bull. Do you focus on weight or conditioning? What kind of feeding program do you need to meet that goal? How do you keep them healthy and productive in the bitter winter conditions common across much of the Prairies? Seedstock producers will likely tell […] Read more

Distal mid-piece defect, often caused by stress, heat or genetics.

Factors that affect bull fertility

Everything from winter shelter to genetics can affect a bull’s fertility

Some bulls are more fertile than others, due to genetics, scrotal size or structure. But poor management can also reduce a bull’s fertility. Since the average bull is expected to breed 25 to 30 cows in a natural breeding situation, his fertility is very important. Dr. John P. Kastelic, professor of cattle reproductive health at […] Read more


Producers are expected to seek guidance from their veterinarian on the optimum method and timing of castration.

What we’ve learned about castration in beef cattle

Research on the Record with Reynold Bergen

When Canada’s 2013 Code of Practice for the Care and Handling of Beef Cattle was being developed, some participants felt it should require pain control for castration at all ages, like the dairy code. The producers and researchers on the beef code committee were confident that pain control was beneficial for feedlot bulls and dairy […] Read more

A calving ease EPD is a better measure than only looking at a potential heifer bull’s head, neck or shoulders, says Travis Olson.

Calving ease top priority when selecting heifer bulls

Calving ease EPD more important than assessing a bull visually, says Alberta producer

When it’s time to choose a heifer bull, expected progeny difference for calving ease tops one beef producer’s list. The birth weight expected progeny difference (EPD) is accurate but it’s simply an average, says Travis Olson of Ole Farms at Athabasca, Alta. For example, two bulls could have an average birth weight EPD of 75 […] Read more


Even the best cow could use a little help to maximize the potential of her bull calf by weaning.

Supplementing young bull calves before weaning pays off

Testes development, fertility greatly impacted by being well-fed

Young bulls need to be fed adequately for proper growth and development, and future fertility, but we are still learning about the best way to feed them, according to John Kastelic, a professor of theriogenology and head of the department of production animal health, in the University of Calgary’s faculty of veterinary medicine. “In beef […] Read more

How castration method and age affect pain in young calves

Research on the Record with Reynold Bergen

Building a seedstock business from scratch

Anyone who raises cattle knows the work is never done, it just changes with the seasons. Raising breeding stock takes that commitment to another level with registrations, shows, and sale preparations often colliding with the start of a new calving season. Despite all of the extras involved, Blair and Stephanie McIntosh knew from the get-go […] Read more

Preg-checking scorecard for cow-calf producers

Vet Advice with Dr. Ron Clarke

Pregnancy checking remains one of the most underutilized management tools in the cow-calf business. Overlooking the chance to gather herd information as cows come off pasture in the fall is a missed opportunity for the cow-calf producer. A trip through the chute in fall should be much more than determining which cows to keep and […] Read more


It's possible with DNA testing to figure out which bull sired your calves, but is it worth the hassle?

Which bull sired that calf?

Parentage testing in multi-sire pastures goes under the microscope

Collecting DNA samples for parentage testing from bulls and the resulting calves from multi-sire breeding pastures is the only way to find out each bull’s value to your operation. A bull might come with a great package of traits you want to see passed to your calves, but the bull’s value is questionable if the […] Read more
