Bovine TB: An old disease, a modern enigma

Vet Advice with Dr. Ron Clarke

The TB investigation in southeastern Alberta continues to unfold. The riddle of where it came from and finding ways to deal with the relative “stranger at our door” is unnerving. When the views of an anxious livestock industry, a federal regulatory agency, and a probing public collide, the task of disease control approaches unmanageable. Add […] Read more

One Health: Recreating the future

Vet Advice with Dr. Ron Clarke

On November 3, 2016, individuals, academics, nonprofit organizations and the corporate world recognized “One Health Day.” This was an opportunity to address the inextricable interaction between animals, environment and humans, and how the veterinary and medical health professions should interact. Barbara Natterson-Horowitz, MD speaking at the 2016 Hill’s Symposium, recognized that the human medical community […] Read more

Atypical interstitial pneumonia in cattle

Vet Advice with Dr. Ron Clarke

Atypical Interstitial Pneumonia (AIP) continues to plague the beef industry in unpredictable ways. Also known as acute bovine pulmonary emphysema and edema, AIP is a common cause of sudden respiratory distress in cattle, particularly adult beef cattle grazing lush pastures through late summer and fall and in feedlot cattle through the finishing period. Sudden onset […] Read more

Anaplasmosis is the most common tick-transmitted disease of cattle worldwide.

Did we walk away from anaplasmosis too soon?

Vet Advice with Dr. Ron Clarke

As of April 1, 2014, anaplasmosis in cattle was removed from the list of federally reportable diseases. The federal government is no longer involved in controlling the disease. Import controls were basically removed. Cows purchased from infected areas of North America are no longer tested before entering Canada despite the fact that testing reduces the […] Read more


What do coffee and doughnuts have in common with beef? 

Animal Health with Ron Clark, Dvm

The Canadian Beef Industry Conference 2016 (CBIC 2016) provoked thought on many topics. Presentations by a host of food industry icons stirred the imagination of the cattle industry, a body once thought inert and cloaked so deeply in tradition and romance that any significant degree of change seemed improbable.Through two solid days of presentations, I […] Read more

Fighting AMR: A true test of human resilience

The ongoing explosion of antimicrobial-resistant infections continues to plague global health care. Our inability to mount significant countermeasures to resistance, while at the same time enduring the decline in research and development of new antibiotics creates a “perfect storm” and the fear we may be on final approach to a pre-antibiotic era of serious and […] Read more



A cluster of E. coli bacteria. As an alternative to using antibiotics for fighting E. coli infections in newborn and weaned pigs, scientists are finding promising results from introducing mixes of beneficial bacteria, obtained from other pigs, into the gut of young pigs.

Vet Advice: Exploring the ‘hygiene hypothesis’

As a veterinarian, I wondered for many years if animals and humans could function normally in an environment free of pathogens, free of stress and devoid of all things considered harmful. What might the balance be between not enough and too much? Are city kids raised in a semi-sterile milieu advantaged or disadvantaged compared to […] Read more

Grazing management: The essence of ranching

Cattle are unique: they came to us as creatures capable of grazing; as ruminants with the ability to convert roughage to energy; and, ultimately, energy to protein. Grazing is how ranches create value. Grazing management is maintaining the balance between soil health, plant growth, sunlight, and moisture on rangeland. The amount of effective moisture — […] Read more

Many strategic deworming concepts have been developed for calves and replacement heifers, but have fallen short for the cow herd, the real economic engine of commercial cattle operations.

Rethinking strategic deworming in beef cattle

Vet Advice with Dr. Ron Clarke

Concepts around deworming the beef cow have moved from “not necessary” to “routine” in many progressive cow-calf operations. The evolution of internal parasite control as an integral component of health management shadowed development of highly effective chemical families that revolutionized parasite control. Reasons for the shift include: Economic studies that clearly demonstrated deworming pays. Evidence […] Read more
