Intensive milk production technologies on a modern complex

Abstract

The article presents the results of research confirming the influence of intensive technologies used in modern dairy complexes on the level of reproduction and productivity of milking herds. It is noted that when heifers are bred intensively in the specialized farm, at the first successful insemination the animals reach a high live weight (350-360 kg) at the age of 330-340 days. A high efficiency of intensive technology of dairy herd reproduction using sexed semen has been established. Thus, the pregnancy rate of heifers from the first insemination was 61.5% and that of cows of the first lactation, taking into account their health condition and the diseases they had undergone, was 41.1%. During calving, 82.9 - 94.3% of replacement heifers were obtained from the control stock of heifers and cows of the first lactation. Researches have shown that intensive technologies of the maintenance, feeding and reproduction herd realized on modern dairy complex provide high milk productivity of animals (the level of milk yield 10,240 kg of milk, mass fraction of fat in milk - 3.98% and that of protein - 3.17%). In the herd more than 3% of animals completed the sixth lactation (the level of milk yield - 9,940 kg of milk, the mass fraction of fat in milk - 4.35% and protein - 3.2%), which demonstrates the prospects of forming the dairy herd with a long period of economic use of cows. Consequently, intensive milk production technologies in modern complexes contribute to the increase of productivity of young cattle and milking cows, ensure high efficiency of reproduction of the dairy herd and, to a certain extent, increase the duration of productive use of animals.
