The article contains materials, artificial insemination, as one of the types of assisted reproductive technologies, has widespread use in dairy and beef cattle breeding. The same cannot be said about such a promising area of the agricultural sector as goat breeding. One of the limiting factors is the negative effect of low temperatures on the morphofunctional characteristics of the sperm cells of breeding goats. The problem of accelerated reproduction of highly productive animals is gaining special priority, using modern methods of reproduction biotechnology in practice, including obtaining and cryopreservation of seed from producers and its use in artificial insemination of the breeding females. The introduction of artificial insemination into the practice of farms and private farms will make it possible to widely use the seed of highly valuable breeding producers, tested for the quality of offspring, reduce the spread of sexually transmitted infectious diseases, control the timing of insemination, ensuring the birth of young animals in a favorable season. When goat ejaculates were frozen and thawed in a new diluent with vitamin E, compared with other analogues, the following results were obtained: sperm motility was 8 points, sperm concentration was 1.7±1.8 bn/ml; the mobility of thawed sperm is 5 points, the absolute survivability index is 93 %. The use of a classical medium with the addition of vitamin E will increase the efficiency of using the gene pool of highly valuable breeding goats.
