<P> An udder is an organ formed of the mammary glands of female four - legged mammals , particularly ruminants such as cattle , goats , sheep and deer . It is equivalent to the breast in primates . The udder is a single mass hanging beneath the animal , consisting of pairs of mammary glands . In cattle there are normally two pairs , in sheep , goats and deer there is one pair , and in some animals such as pigs there are many pairs . In animals with udders , the mammary glands develop on the milk line near the groin , and mammary glands that develop on the chest ( such as in humans and apes ) are generally referred to as breasts . </P>
