When is the vaccination for leptospirosis typically administered to pigs in a farrow-to-finish operation?

• A. At weaning
• B. Pre-breeding
• C. Post-breeding
• D. Before weaning

Answer: (B)

The vaccination for leptospirosis is typically administered pre-breeding in a farrow-to-finish operation. This timing is critical for ensuring that sows and gilts develop immunity before they become pregnant, which is vital to protecting both the mothers and their offspring. Vaccinating before breeding helps to prevent the transmission of leptospirosis to the embryos, reducing the risk of reproductive failures, stillbirths, and weak piglets. Consequently, this proactive approach helps maintain herd health, improves reproductive performance, and ultimately leads to better productivity within the operation.
