In About the Abstract, the experts discuss a study by Cordial and Carrie (2024) in the Journal of Animal Science, which compared the impact of metaphylaxis with Tulathromycin versus saline on high-risk beef stocker calves over 42 days. The study found that calves treated with Tulathromycin had higher average daily gain, especially in the first 14 days, and fewer treatments for respiratory disease. Culture results showed more bacteria in saline-treated calves at follow-up. Antimicrobial use was higher in the Tulathromycin group, but the number of regimens was similar. The study suggests that metaphylaxis may improve health and performance while managing antimicrobial resistance.
