IMPROVING THE GENETIC POTENTIAL OF PRODUCTIVITY AND REPRODUCTIVE WOOL QUALITIES OF MEAT-AND-FAT SHEEP

In Kazakhstan, sheep farming is the leading branch of agriculture. This is due to the unique natural, economic and climatic conditions associated with the nature of the terrain, as well as centuries-old traditions. Since ancient times, almost everywhere in Kazakhstan, sheep farming was based on the use of vast pasture lands. Edilbaevskaya sheep bred in the herd of the Yerzhan farm are characterized by high meat and fat productivity, early maturity and good adaptability to the natural, climatic and forage conditions of the southeast of Kazakhstan. The average weight of rams in the breeding group is 105-110 kg, wool yield is 3.2-3.5 kg, ewes, respectively, 73-76 and 2.2-2.4 kg. The average daily weight gain of rams from birth to weaning is 290-296 g, and 260-270 grams for ewes. Live weight and wool class are important selection traits for selection and selection for Edilbaev sheep of the Yerzhan farm when improving the productive and breeding qualities of sheep in the flock. It has been established that when selecting by live weight, it is recommended to sell rams for meat in two periods, taking into account market demand, at the age of 7-8 and 18 months.
