What is the vaccine requirement for calves regarding Brucella vaccination?

The vaccination requirement for calves regarding Brucella vaccination stipulates that calves must be vaccinated between 4 and 12 months of age. This guideline is put in place to effectively reduce the prevalence of brucellosis, a significant disease that can affect cattle and cause serious reproductive issues. Vaccinating calves during this window ensures that they develop immunity before they reach sexual maturity, which is crucial for controlling the spread of the disease within herds and protecting the overall cattle population.

It's important to note that the vaccination is not optional, especially in areas where brucellosis has been identified, nor is it exclusive to bulls; instead, both male and female calves are included in the vaccination protocol. Vaccinating at birth would not provide adequate time for the immune system to respond effectively, highlighting the importance of the specified age range for vaccination.
