THE USE OF FROZEN-THAWED SPERM OF SHEEP PRODUCERS WITH A SHELF LIFE OF ONE YEAR

Abstract

Currently, there is great progress in solving the problem of cryopreservation of sperm from sheep producers. At the same time, it is necessary to continue conducting scientific research to study the features of the structure and function of sheep sperm at low temperatures and to develop highly effective methods for long-term preservation of sperm in a frozen state. The conducted studies demonstrate the possibility of long-term storage of the seed of sheep producers in liquid nitrogen without reducing its quality indicators and using it to produce offspring. An important role in sheep breeding is given to the use of breeding rams, which can provide significant genetic progress in the breed. Of particular importance is the introduction into practice of the method of freezing the seed of sheep producers. Thanks to this method, prospects have opened up for serious breeding work in sheep breeding, conservation and rational use of the gene pool of outstanding sheep producers. This article presents the scientific results of studies conducted on the use of frozen-thawed sperm of sheep with a shelf life of one year. The effective use of frozen sperm in sheep farming is justified, as labor and financial costs are significantly reduced. Producing sheep can be used regardless of their location and distance, to transport sperm over long distances and use it at the moment when it is necessary.
