Abstract
Abstract It is proved that milk yield in winter is characterized by a decrease in the absolute indicator of the average daily milk yield with a simultaneous increase in the mass fraction of fat in milk in camels, regardless of the breed and the zone of their breeding. On average, the milk yield in December - February for camels of Arvan breed was from 4.8 kg to 6.4 kg, with a mass fraction of fat in milk of 4.6 - 4.7%. In winter, the milk yield of the Kazakh Bactrian camels in comparison with the peers of the Arvana breed of the “bestorrangyla” plant type is 2.5 times lower. The female camels of the Kazakh Bactrian in the first and second months of the winter period did not experience a sharp decrease in milk yield and on average December 2.5 - 3.0 kg and January 2.3 - 2.8 kg. At the end of the winter period - in February it drops sharply and reaches the level of 1.6-2.1 kg. At the same time, the fat content of milk in the winter period is in the redistribution of 5.9 – 6.2%.
