There are several differences between dairy and beef cattle. Beef animals are well-muscled animals with powerfully built legs. They are bred and fed to produce high quality lean meat, with a minimum of bone or fat waste. Dairy animals are more angular in shape than beef animals. Dairy cows are bred and fed to produce milk, not meat. The udders (the bag between the cows’ rear legs where milk is stored – the mammary system) of dairy cows are often larger and may hang lower than the udders on beef cows.
