INFLUENCE OF TECHNOLOGICAL EQUIPMENT ON THE CLINICAL AND HEMATOLOGICAL STATUS AND PRODUCTIVE QUALITIES OF COWS IN THE CONDITIONS OF THE IRKUTSK REGION

Comprehensive studies have been conducted on the comparative assessment of the influence of the method of maintenance and technological equipment on the clinical, physiological, hematological and productive indicators of cows in the climatic conditions of the Irkutsk region. The results of the conducted studies indicate the high degree of importance of maintaining optimal parameters of the microclimate of cowsheds in the harsh climatic conditions of the Baikal region and the use of modern automatic equipment. Significant temperature changes in the cowshed during the seasons have a negative impact on the behavior and health of the animal. Excessive temperature and humidity readings lead to a deterioration of appetite, a decrease in feed consumption and a decrease in animal productivity. At low temperatures, there is an increased consumption of feed, which is associated with the need to obtain energy aimed at warming the body without a positive effect on milk productivity. Also, under equal microclimatic conditions of cowsheds, a more positive effect on the economic and useful indicators of Siberian cows with a loose method of maintenance compared to a tethered one was noted. With loose technology, cows have the best indicators of resistant qualities, metabolism and milk productivity, while increasing the automation of production processes, increasing the level of labor and profitability of production. The given advantages of a loose method of keeping, a calm disposition and a technological predisposition of Siberian cows indicate the optimal use of this technology for keeping the cows under study in the conditions of the Irkutsk Region.
