THE EFFECTIVENESS OF MODERN METHODS OF DETECTING COWS AND HEIFERS IN HUNTING
The article provides information about the modern method of detecting heifers in hunting. In the conditions of a specialized herd reproduction enterprise, the effectiveness of using a collar with a sensor for monitoring the sexual activity of heifers was noted. The high efficiency (66%) of determining hunting in heifers by motor activity is shown. On a significant livestock, heifers were evaluated in various ways according to the pregnancy index, insemination number, insemination cycle and pregnancy index, taking into account the calendar month.
Using innovative autonomous control of reproduction of young animals using the SCR Heatime system, 3-5% more heifers were identified ready for insemination than with the traditional method of visual identification. In addition, already at the age of 11 months, up to 43% of animals ready for fertilization can be detected, and with the traditional method, their share was only 4%. It should be noted a decrease in the consumption of semen per heifer for the entire accounting period by 0.1. This makes it possible to significantly reduce the cost of insemination of heifers, which is carried out only with sexed seed, which has a significantly higher cost. Based on the research results, it is possible to recommend the use of the SCR Heatime system not only to identify repair heifers in hunting, but also cows in highly productive herds of dairy farms and complexes.
