What are supernumerary teats in dairy calves?

Excessive nipples are a congenital condition.

They are usually shorter than normal nipples and have thinner walls. Excessive teats are the most common birth defect, and this condition can be inherited by dairy cows. There have been few genetic selections away from this trait in heifers, simply because they have not been reported to the artificial insemination stud service and the problem is treated very easily. How many teats are there on the cow's udder? Many believe that cows have only four teats. However, about 50% of cows have one or more extra teats.

These extra teats do not work and are not harmful, but they can leak during milking and, in some cases, become infected. In the dairy industry, excess nipples are usually removed.
