A variety of genetic tests are now available for livestock and more are expected in the future that can be used to direct breeding decisions and improve herds. | FILE PHOTO

Genetic testing useful for selecting breeding animals

The Human Genome Project should receive partial credit for giving us the technological advancement and innovation necessary to conduct widespread genetic research. The project, which completed the first sequence of the human genome, finished in 2003. This massive undertaking led to the development of rapid and automated genetic sequencing. It has trickled down into many […] Read more

Scientists use a few common behaviour tests to assess personality traits in animals, including the chute score and the novel object test.  |  File photo

Animal personality can impact welfare and production

It is obvious to anyone who spends time with animals that each is an individual with a unique personality. Experts define personality as an individual’s behavioural traits that are related and remain unchanged throughout time and situations. The term is sometimes used interchangeably or slightly differently than temperament. As with many things in science, personality […] Read more


White nose syndrome has decimated bat populations in North American, and a recent study validates previous predictions that the loss of this species and its role in biological pest control would negatively impact agriculture.  |  File photo

Study finds bat population crash increases insecticide use

I’ve written before in this column about the bat disease that has decimated North American populations. As a brief refresher, white nose syndrome is a disease caused by a fungal pathogen that was introduced into the state of New York in 2006. The fungus causes a skin infection, making a characteristic white fuzz around the […] Read more

Mosquitoes not only spread viruses but also parasites, such as the one that causes heartworm infections in dogs and cats.  |  File photo

Mosquitoes can spread significant animal pathogens

As with my previous column on flies, it is hard to come up with anything positive to write about mosquitoes. In an optimistic take on these tiny insects, Ned Flanders from the TV show The Simpsons commented, “sure are fun to scratch — satisfying.” There are approximately 3,600 known species of mosquitoes ,and scientists classify […] Read more


The parasite, Strongylus vulgaris, was considered to be well controlled by modern deworming medications. However, veterinary pathologists at the University of Calgary undertook the study after noticing an apparent increase in the number of horses affected by this parasite. | File photo

Study shows deadly horse parasite alive and well in Alberta

A recent Alberta study of horses found that a particular parasitic infection is more common than previously thought. The parasite, Strongylus vulgaris, was considered to be well controlled by modern deworming medications. However, veterinary pathologists at the University of Calgary undertook the study after noticing an apparent increase in the number of horses affected by […] Read more


A study of cases in which dogs were poisoned by rodenticides found that nearly half of them had bleeding into their chest cavities, which can be difficult to identify.  |  File photo

Most rodenticide-poisoned dogs survive with treatment

Rodent poisons, also known as rodenticides, have long presented a hazard to animals other than their intended victims. Dogs and wildlife such as owls, hawks, eagles and other raptor bird species are frequently exposed to these products. The consequences of poisonings have increased with development of second-generation products, which have a significantly longer effect on […] Read more



Medical conditions that can affect draft horses such as Clydesdales include exertional rhabdomyelitis and a disorder of the larynx.  |  File photo

Draft horses are susceptible to unique health challenges

Once the mainstay of prairie agriculture, draft horses are now much less common. The most familiar breeds on the Prairies include Belgiums, Percheron, Clydesdales and Shires. Horses, including draft breeds — and also thoroughbreds — can suffer from a disorder of the larynx. Nerve damage inactivates the muscle that normally opens and closes the left […] Read more
