Skeletal deformities of beef calves

Vet Advice with Dr. Ron Clarke

By
Much is written about genetic mutations in beef calves: why it happens, pathological descriptions and how to manage the deformities. Pathologists love to describe structural abnormalities of organ systems and what else has been discovered.

Managing parasite resistance to livestock dewormers

There’s no easy way to extinguish resistance to dewormers, but producers can manage it and control parasites

By
The debate is over on whether internal parasites are developing resistance to dewormers in Canadian cow herds, as far as the research is concerned.

Surviving scours

Prevention is the best medicine, but when you’re in the middle of an outbreak, it’s all about getting through it

By

And in the middle of an outbreak, the focus is on survival, for calves and humans alike. During an outbreak, producers are generally going to see a […] Read more

Tech for cattle disease diagnostics edges into the Star Trek age

Researchers are testing new, compact equipment to see if it can quickly and accurately diagnose specific pathogens that cause BRD in the field and feedlot

By
Remember the COVID rapid test? That was a point-of-need test designed to find a target and match it to a “binder” which then changes the colour if it’s positive or negative. The same principle is applied to the rapid lateral flow device test for anthrax, Dr. Anatoliy Trokhymchuk explains, which was developed by the U.S. […] Read more

Urolithiasis: a pasture and feedlot conundrum

Vet Advice with Dr. Ron Clarke
