To begin feeding starved cattle, the number involved and feed sources require consideration.

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

‘I’ve seen serious bouts of salt poisoning when cattle are deprived of water through periods of heat, then gain free access to fresh water and end up dying.’ – Ron Clarke.

Protecting beef cattle from extreme heat and cold

Veterinary Case Study: 2023 was one of the warmest in memory, and climate change is only getting started

Sixty years with the cattle industry has created many stories for me — good, bad and funny. Veterinarians don’t get called to many good ones, but there are a few funny stories mixed in with the many tales chronicling sickness and dying. Fortunately, more animals respond to treatment and recover than not. Bills get paid. […] Read more



Wild pigs raise several litters a year, and litters average six piglets on the Prairies.

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


“Most fractures we see in young calves are not open wounds or compound fractures, so there’s no infection. But if we don’t do a good job of protecting a broken limb and it becomes open, the chances for survival plummet quickly.” – Dr. Andy Acton.

Limb injury in newborn calves

Vet Advice with Dr. Ron Clarke

Calving time is just down the road and questions dealing with limb injuries in newborn calves are about to become daily entries in large animal clinics serving beef herds. 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

Ergot: Madness meets modern medicine

Vet Case Study: The risk of ergot toxicity has only grown for cattle, but ergot alkaloids can also be used in human medicine

Ned had a question one morning when he stopped by the clinic for vaccine. “Is ergot still a problem in cattle feed?” “We seem to worry more about ergot today than we did thirty years ago,” I replied. “Don’t know exactly why, but I think cropping practices changed as did our concern about ergot. Headlands […] Read more


It’s much easier to write about treatment than get it done effectively. Many animals die from grain overload.

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

Producers need to think about how to wean and when to wean their calves.

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


E. coli bacteria.

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

“There are three kinds of men. The ones that learn by readin’. The few who learn by observation. The rest of them have to pee on the electric fence for themselves.” – Will Rogers.

Cattle rustling remains ‘one of great mysteries of the range’

Rustlers are still pilfering cattle, often with the help of modern technology

To quote a CBC article in the Cochrane Eagle, “For as long as there have been cattle, people have been stealing them.” In my view, it may be the second-oldest profession in the world.  While brand inspectors check auction markets in B.C., Alberta and Saskatchewan, no such system exists in Manitoba or Ontario. The lack of […] Read more
