THE STATE OF MODERN SHEEP REPRODUCTION TECHNOLOGY IN KAZAKHSTAN

Abstract

Today, sheep farming is one of the most important branches of the agro–industrial complex of the country, which, in some cases, is the only source of obtaining the most important types of products – wool, mutton meat, fur and sheepskin coats. Currently, there is great progress in solving the problem of cryopreservation of RAM sperm. In addition, it is necessary to conduct scientific research to study the features of the structure and function of RAM sperm at low temperatures and develop highly effective methods for long-term storage of sperm in a frozen state. The studies carried out indicate the possibility of long-term storage of RAM sperm in liquid nitrogen, without reducing its qualitative indicators and using it for offspring. An important role in sheep breeding is played by the use of breeding Rams, which can ensure significant genetic progress. One of the most important, long-established areas of sheep breeding in Kazakhstan is meat and fat. Further promotion of this branch of sheep breeding requires not only expanding the scale of the introduction of artificial insemination into production, but also comprehensive improvement of its organizational forms and technical methods. Now in the Republic, attention is paid not only to the quantitative growth of livestock, but also to its qualitative transformation, since the preservation and improvement of sheep breeds is an important measure of economic growth. The studies carried out showed the possibility of using frozen thawed spermatozoa of avassi breed Rams with a shelf life of one year. In terms of the main performance indicators and biological properties when inseminating Kazakh tailed females, the obtained hybrid Cubs are not inferior to the Kazakh coarse-haired coarse-haired sheep.
