Summary: The aim of the study was to study the effectiveness of the use of sexed semen on the broodstock cattle of Holstein cattle. The subjects were cows, calves, heifers, sex and normal semen. The subject of the study is reproductive indicators, fertility, calf yield. The tasks included the analysis of the main indicators in the dairy industry of the use of sexed semen; comparative evaluation of indicators in animal husbandry when using sexed and normal sperm. It has been experimentally established that insemination with sexed sperm accounts for 82.95% and normal sperm for 17.21% of the total number of animals. The yield of calves from insemination with sexed sperm is 55.19%, normal - 44.81%. 159 heads, or 10.38% more calves, were obtained from mating livestock with sexed semen. The use of sexed semen reduces the ability to fertilize animals by an average of 25.0%. For 1 hryvnia invested in the purchase of semen, divided by sex, the company receives a profit of UAH 7.16, which convinces of the high profitability of its use.
