Non-O157 Shiga toxigenic E. coli (STEC)

Did we walk away from anaplasmosis too soon?

Vet Advice with Dr. Ron Clarke

Pneumonia: the disease that won’t go away

The three categories of pneumonia and how to tell them apart

The potential of probiotics to promote greater livestock health

Unlike antibiotics – which kill bacteria – probiotics are live cultures of beneficial bacteria

By
Last year Health Canada changed its regulations on antibiotics to prevent them being used as growth promoters in livestock. Drug makers like Bayer, Merck, and Novartis had already begun the change, removing labels on their products that advertised them as suitable for non-medicinal purposes. Antibiotics are still available to Canadian ranchers and feedlot operators but […] Read more
