Abstract
The prospect for the development of meat-fat sheep farming in the Republic of Kazakhstan is also the intensification of selection and breeding work to realize the potential genetic capabilities of fat-tailed sheep, taking into account the specificity of the food supply, feeding, maintenance of the reproductive composition of breeding sheep with a breeding accounting software package, biometric processing of research materials with the introduction of computer technology with maximum using functionality. The use of mobile points for artificial insemination of queens, the use of OCS and milk semen diluents, laser bioactivation provides the opportunity to achieve financial savings and increase the profitability of sheep farming by 26-42% compared to the traditional way of running the industry. The sheep bred in the herd of the Erzhan farm are characterized by high meat and fat productivity, early maturity and good adaptability to the natural, climatic and feeding conditions of south-east Kazakhstan. The average weight of rams from the selection group is 110–120 kg, wool shearing is 3.2–3.5 kg, and ewes are 73–76 and 2.2–2.4 kg, respectively. The average daily weight gain for rams during the period from birth to beating is 290–296 grams, for lambs 260–270 grams. When improving meat-fat fat-tailed coarse-wool sheep of the Erzhan farming enterprise, it is necessary, first of all, to take into account the live weight of the producers used when selecting rams for this trait: it should be higher than the live weight of the ewe by 1.4 - 1.6 times.
