MORPHOLOGICAL FEATURES AND FUNCTIONAL PROPERTIES OF AN UDDER OF SIMMENTAL COWS
Different production types of Simmental cows were studied. The shape and size of an udder and nipples, the rate of milk flow were researched. It is found that the shape of an udder and its size depend mainly on the degree of individual udder lobes development. The shape of an udder is closely related to the dairy productivity of cows. It is revealed that the milk productivity of animals has a direct relationship with their belonging to different production types. The obtained data meet the approximate requirements for the evaluation of udder nipples. The length of the front nipples is 6.2-6.4 cm, posterior - 4.6-4.9 cm, diameter - 2.3-2.6 cm. The rate of milk flow of dairy cows, is 2.25 kg/min, which is higher than in dairy- and- beef cows or beef-and-dairy cows by 0.09-0.14 kg/min. It is determined that the rate of milk flow is related to the belonging of animals to different production types.
