MORPHOLOGICAL AND FUNCTIONAL PROPERTIES OF AN UDDER OF HEIFERS OF RED PIED BREED AT JSC "LUCH" IN THE AMUR REGION
The creation of highly productive herds, well-adapted to industrial maintenance technology and machine milking, will become of paramount importance for breeding in intensive dairy cattleraising. One of the widespread breeds among highly productive cattle of our country is red pied cows. The main method of improving the red pied cattle is purebred breeding, which is implemented by intensiveuse of the country's own breeding resources, as well as the use of bulls of the leading lines of Holstein cattle. The research carried out by a number of scientists: A.I. Bich, E.I. Sansa, year 1976, A.I. Prudova, year 1999, L.I. Kibnalo, year 1993, V.V. Alifanova, Ya. V. Vostroilova and others, year 1998, found out that the use of Holstein bulls increases the genetic potential of milk yield, improves the morphological characteristics and functional properties of the udder. According to the literature on the subject the researches have been carried out into the properties of udder and milk yield, variability, inheritance and the relationship of some characters showing the suitability of cows for machine milking. It is proved that in many herds up to 20% of cows are unsuitable for effective milking by devices
