Dairy calves and dairy goat kids may be born with extra teats on the udder, called supernumerary teats. These extra teats are non-functional and not harmful but may leak during milking or, occasionally, become infected. In the dairy industry, supernumerary teats are usually removed.
The RSPCA believes that the clipping/removal of supernumerary teats of dairy calves and kids for aesthetic reasons only must not be performed.
