What is the age range during which calves must be vaccinated for Brucella in California?

The appropriate age range for vaccinating calves against Brucella in California is from 4 to 12 months. This timing is essential for providing the calves with immunity against Brucellosis, which is a significant infectious disease that can affect cattle and pose health risks to humans.

Vaccinating during this period ensures that the animals are protected before they reach sexual maturity, as Brucellosis is mainly transmitted through breeding and can have severe repercussions for productivity in cattle herds. Administering the vaccine within this range maximizes the chances of developing an effective immune response while minimizing the risk of the disease spreading within the herd or to humans.

It's important to carry out these vaccinations following the recommended schedule for preventing Brucella infections, helping maintain biosecurity and promote overall cattle health in the agricultural community.
