Prevent External Parasites from Bugging Your Cattle

This live webinar was held March 12, 2020.

External parasites can reduce weight gains, cause losses in milk and meat production, produce general weakness, cause mange and severe dermatitis, and create sites for secondary invasion of disease organisms. This webinar discusses methods on how to prevent and treat external parasites on cattle.

This webinar is available for one CE credit for RVTs and DVMs across Canada. After watching the entire webinar recording, you may take the quiz to receive a CE credit.
