In two previous posts, we showed a cow giving birth and then the first 70 days or so of that calf's life on a dairy or calf ranch. Once they get past the first few months, they are then moved to a "big girl" corral where they can run around and intermingle with the other calves their age. These are called "running pens." The young heifers are usually grouped by their age so as to make it easier to watch them grow.
One of the jobs the farm vet performs at this stage in the heifer's life is vaccinating for Brucellosis. This is a requirement for cattle owners in the state of California. The heifers are vaccinated at four to six months of age. Brucellosis is a zoonotic disease, which means it can be transmitted to humans. This is why it is of extreme importance that these animals receive the vaccination. Of various types of infections, people become infected by contact with fluids from infected animals (sheep, cattle or pigs) or derived food products like unpasteurized milk and cheese. Once vaccinated, animals get a tattoo in their ear and an identification tag to show it has been properly done by an accredited veterinarian.

Please take a minute to watch the video here that shows the farm vet vaccinating some jersey heifers on a dairy. It is quick, painless and part of the normal routine!
Here are some photos of the farm vet vaccinating cattle at a beef ranch.
