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

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
