Poisonous plants are a major cause of economic loss to the livestock industry. It’s estimated poisonous plants adversely affect three to five per cent of cattle, sheep and horses grazing the western range.

Hemlock: A deadly poison affecting spring and summer pasture
Vet Advice with Dr. Ron Clarke
Have we learned anything about controlling zoonotics from COVID?
It was an anniversary of sorts this spring, with COVID officially turning four years old. Meanwhile, avian influenza leapt into ruminants, becoming known as bovine influenza A virus. Globally, COVID killed over seven million. Where it came from is still debated by scientists, but probably from a Wuhan fish market in China and probably from […] Read more
Assessing malnutrition in beef cows: Part 2
Vet Advice with Dr. Ron Clarke
Through my years in practice and my career afterwards, I could never accept the fact that some producers starve cattle. Malnourished cattle almost always occurred through winter and, inevitably, the lack of care of the cow herd meant all animals on a particular farm or ranch suffered. Horses were bone racks, the farm dog skeletal, […] Read more
Assessing malnutrition in beef cows: Part 1
Vet Advice with Dr. Ron Clarke
I never cease to wonder why some producers starve cattle through the winter. Fortunately, they represent a very small percentage of producers, but their lack of care has a big effect on those who drive along the road and see starvation first-hand — downer and dead cattle left in plain sight, matts of hair on […] Read more
Feral hogs — the problem persists
This article is not specifically about the business of beef except to cover the potential effect disease transmission plays and the ecological damage invasive species can wreak, either directly or indirectly. Wild pigs continue to expand out of control in Canada. We’ll also dive into the really bad decisions agriculture producers made in the 1980s […] Read more

Next, are dairy calves with crippling limb injuries throughout the year. Many require veterinary care. Limb injuries fall into the following areas: Most veterinarians agree that […] Read more
Grain overload in cattle
Vet Advice with Dr. Ron Clarke
Only a few calls in practice were totally disheartening. Grain overload in a group of pregnant brood cows three months from calving at -25 C turned out to be one of the worst. By the time producers noticed signs of grain engorgement, cows were often really sick: staggering, down and unable to rise, dehydrated, rumen […] Read more
Decision tree busy come calf weaning time
Vet Advice with Dr. Ron Clarke
During 2023, work, family events and funerals carried me across ranching country from Grand Prairie in Peace River country to Maple Creek on the Saskatchewan side of the Cypress Hills. The travel took me through a patchwork of pastures alternating from satisfactory to barren depending on precipitation. Cow condition varied from good and sleek to […] Read more
How did the E. coli outbreak happen in Calgary’s daycares?
Vet Advice with Dr. Ron Clarke
Debacle is not a word I use much. It’s too harsh, especially when describing disease. Debacle denotes a “violent collapse” or “a fiasco.” However, I’m convinced — based on what I read about what consumed Calgary daycares — that debacle best describes what’s going on across town in one of Canada’s most modern cities, with […] Read more
Urolithiasis: a pasture and feedlot conundrum
Vet Advice with Dr. Ron Clarke
Bladder stones, or obstructive urolithiasis, are a significant cause of morbidity and mortality in male ruminants, especially steers. Uroliths form from protein and mineral components of the diet. Protein components may include cells produced during vitamin A deficiency, sutures, tissue debris, blood clots, excess protein or bacteria in the urine. Typically, stones develop in the […] Read more
