§ 10351 Dairy Calf Vaccination

• •All female dairy calves must be vaccinated.
• •Vaccination must be done by an official or accredited vet authorized by the department.
• •The department decides the ages when the vaccine must be given.
• •Male dairy calves and beef calves can be vaccinated only if the owner decides to do so.

A dairy farmer has a newborn female calf. The state department says calves should be vaccinated at 3 weeks old. The farmer calls an official veterinarian, who gives the calf the required vaccine at that age.

Because the calf is a female dairy calf, the law requires the vaccine and it must be given by a vet approved by the department. If the farmer had a male dairy calf, he could choose whether or not to vaccinate it.
