Antibiotic use records are important for producers who want to track the effectiveness of the antibiotics they use. Industry groups need antibiotic use data to refute misleading claims about our production practices. Even restaurant chains and meat companies marketing “antibiotic-free” beef need records to keep treated animals out of their “never-ever” supply stream. When it comes to antibiotic use in the beef industry, most of the attention is focused on the feedlot sector. That’s because most of the antibiotic use occurs there, and because large feedlots work closely with specialized veterinarians and have developed sophisticated software to support animal health protocols and recording of animal health treatments. But antibiotic use at the cow-calf level is also important. For example, calves may not respond as well to antibiotics at the feedlot if they have been exposed to a related antibiotic before leaving home.
The most recent reports on antibiotic use in cow-calf operations in Eastern Canada (Canadian Journal of Veterinary Research 72:109) and Western Canada (Preventive Veterinary Medicine 90:55) are nearly 10 years old. The Western Canadian Cow-Calf Surveillance Network (WCCCSN) initiative supported under the 2013-18 Beef Science Cluster provided an opportunity to gather updated information regarding antibiotic use on cow-calf operations.
What they did: Dr. Cheryl Waldner and co-workers at the Western College of Veterinary Medicine surveyed 100 cow-calf operations in Alberta, Saskatchewan and Manitoba about Continue reading
