Quick Answer

Pigs should be vaccinated annually, typically in early spring, against diseases such as Brucella, Leptospirosis, and PRRS. Booster shots may be required in 4-6 weeks. Consult a veterinarian for specific vaccination schedules and recommendations.

Vaccination Schedule and Recommendations

When raising pigs on a homestead, it’s essential to establish a vaccination schedule that protects against common diseases. Typically, piglets are vaccinated at 4-6 weeks of age, with a booster shot given 4-6 weeks later. These initial vaccinations protect against diseases such as Brucella, Leptospirosis, and Porcine Reproductive and Respiratory Syndrome (PRRS).

Disease-Specific Vaccination Protocols

Different diseases require specific vaccination protocols. For example, against Brucella, a series of vaccinations is administered at 4, 6, and 8 weeks of age, with a booster shot given annually. Leptospirosis vaccinations are typically administered at 4-6 weeks of age, with a booster shot given 4-6 weeks later. PRRS vaccinations are usually administered at 4-6 weeks of age, with a booster shot given 4-6 weeks later.

Record Keeping and Consultation

To ensure effective vaccination protocols, it’s crucial to maintain accurate records of vaccination dates, types, and manufacturer information. Consult with a veterinarian to determine the best vaccination schedule and protocol for your homestead’s specific needs. They can help you develop a customized vaccination plan that takes into account factors such as disease prevalence, herd health, and individual pig health.
