Core vaccines recommended for western Canadian beef herds

When looking at vaccinating for diseases beyond the core vaccination recommendations, consider the disease risk, vaccine efficaciousness and the cost-benefit of each vaccine

By , ,
Just because there is a vaccine on the market to prevent or reduce disease risk, that doesn’t mean that you need to use it in your herd, unless it is a core vaccine and proven effective and safe. Base your vaccination decisions on sound, objective scientific data. Weigh the pros and cons of vaccination for […] Read more

Producers have until June 16 to comment on proposals

By ,
The Canadian Food Inspection Agency is now seeking comment on its proposed amendments to livestock identification and traceability regulations.

Comment: Is Canada ready for a foot-and-mouth outbreak?

By
Last column I outlined a brief history of the 1951- 52 foot-and-mouth outbreak around Regina, Sask. We haven’t had a foot-and-mouth outbreak in this country since, but it remains a global threat. The World Organization for Animal Health estimates that it affects 77 per cent of the global livestock population, circulating in Africa, the Middle […] Read more

Veterinary Case Study: An effective biosecurity plan is essential to prevent infectious diseases from entering your herd

Jim visited the office one morning and asked if we could talk. He looked worried, a bit like a child that had gotten into the Halloween candy early.

Johne’s disease — not gone but often forgotten

Research on the Record with Reynold Bergen

By
Johne’s disease is sometimes compared to an iceberg — the visible cases are only a tiny fraction of the problem. The biggest part is hidden beneath the surface, particularly in the early stages of disease. In the silent stage, cattle that were infected as calves by a manure-contaminated udder, water or feed show no clinical […] Read more
