Pregnant Cows: Pregnant cows are vaccinated approximately 4-6 weeks before calving. This vaccination helps to ensure that the cow produces antibodies that will protect her calf from disease.
Heifers: Heifers should receive their first vaccinations around 6-8 months of age. These vaccinations include those for reproductive diseases, such as brucellosis and vibriosis.
Mature Cows: Mature cows should be vaccinated regularly, typically once or twice a year. The specific vaccinations recommended will depend on the region and the prevalent diseases in the area.
It's important to follow a veterinarian's recommended vaccination schedule to ensure that cattle receive the necessary protection from diseases. Vaccination protocols can vary depending on the location, climate, and specific disease risks.
