Infections that localize to the heart are rare but serious in any animal. A recent study published in the Canadian Veterinary Journal by Dr. Brianne Henderson and colleagues at the University of Guelph’s Ontario Veterinary College sought to better understand heart infections in horses. They focused specifically on infections of the heart valves, which is […] Read more

Reproductive success can depend on sexual motivation
Reproductive success is key to profitability for cow-calf operations. To achieve this success, two things have to happen. First, our breeding cows and heifers must cycle early in the breeding period. Second, they must conceive when bred. The first factor is largely influenced by the nutritional program and body condition of the cows and heifers. […] Read more
If branding is deemed necessary, it must be done right
Branding remains necessary in many modern cattle operations because it is still the only permanent form of cattle identification. We must make the effort to do it well. In this column, we will look at hot iron branding. A good brand should be legible from quite a distance. In Alberta, Livestock Identification Services carries out […] Read more
Colostrum — nature’s amazing first milk
With calving, lambing, foaling and kidding seasons upon us, something that may be top of mind for many producers is colostrum. It is the first milk produced by lactating mammals and in our livestock species is critical for health, growth and longevity. During gestation, the placental layers in ruminants and horses prevent antibodies from passing […] Read more
Dystocia, calf vigour and colostral intake all connected
As the weather begins to warm up, many beef herds in Western Canada are in the midst of calving season. Producing and weaning live calves is an obviously critical component of cow-calf profitability and problems that occur at this time can have significant consequences. The birthing period and the subsequent first few days of life […] Read more

First, we have to look at the number of seats available for veterinary students in general. There is a rumour that seats for Alberta students went up with the addition of 20 seats at Alberta’s […] Read more
Consider upstream factors when investigating disease
The other day, I presented a case of a deceased wolf to the veterinary students’ pathology rounds. This is a weekly event at the University of Calgary where veterinary pathologists take turns showing and discussing interesting cases to create a less formal learning experience for the students in the program. Like many things this year, […] Read more
It’s important to know when to intervene during calving
At calving time, we would prefer to have every cow and heifer calve on their own and deliver a live calf. We try to ensure this by wisely selecting bulls in terms of birth weights and EPDs for calving ease, by ensuring a top-notch heifer management and selection program, and by providing good nutrition and […] Read more
A new age arrives in breeding soundness evaluations

Pulling out infertile bulls and finding bulls with other problems is now common practice […] Read more
Earlier bull sales can complicate semen evaluations
Purebred bull sales in all breeds appear to be happening earlier and earlier in the year, some even occurring in December. This is months before many cattle producers plan to use them in their breeding programs. It can create difficulties for veterinarians to get these bulls’ semen evaluated ahead of time. Both sellers and buyers […] Read more
