In general three types of supernumerary teats have been observed in cattle (GIFFORD1, 934) :
Caudal teats, are teats located at the rear of the normal.
Zntercalary teats, are those found between the normal teats.
Ramd teccts, supernumeraries that are a ramification of the normal
Some of this supernumeraries may be without glands, others are orifices of small glands, and yet others may open into one of the normal glands.
