• Give lambs their first vaccine at 6-8 weeks of age
• Administer booster shots at 10-12 weeks
• Schedule annual vaccinations against enterotoxemia pasteurella pneumonia
• Time vaccinations before expected disease pressure periods
• Keep detailed vaccination records for each animal

Best Practices for Vaccination

• Store vaccines at 35-45°F in a dedicated refrigerator
• Use sterile needles for each vaccination session
• Implement strict quarantine for new animals for 21 days
• Monitor the flock daily for disease symptoms
• Separate sick animals immediately
• Clean equipment between different groups
• Follow label instructions for proper dosage rates
• Document all treatments administered

Adopting Best Practices For Lamb Care

Implementing systematic care practices significantly reduces lamb mortality rates while promoting healthy flock development.

Proper Identification And Record Keeping

Implement individual lamb identification within 24 hours of birth using ear tags or RFID systems. Track birth weights parentage medications vaccinations growth rates, and medical treatments.
