Abstract

The objective of the Canadian Beef Production Limiting Diseases project was to conduct provincial serological surveys across Canada for production limiting diseases in cow-calf herds. The diseases were chosen because they are three diseases known to occur in Canada and all have subclinical carrier states. Each of these diseases has significant economic implications in terms of trade or reduced productivity, and none are easily controlled using conventional treatment methods. The diseases chosen to estimate prevalence for were bovine leukosis virus (BLV), Mycobacterium paratuberculosis (Johne's Disease) and Neospora caninum (Neosporosis). Provincial surveys had already taken place in dairy cattle, and two provinces (Manitoba and Quebec) had already performed surveys of beef cattle.
