The results of experiments conducted to study the fertility of queens have shown that, depending on the class affiliation, the yield of lambs per 100 surrounding queens ranges from 111-105.4%. It should be noted that the largest number of lambs was obtained from queens of the selected elite group (111%), which is 5.6% higher than the number of lambs obtained from queens of the first class. A varietal analysis of the passport runes showed that with a decrease (coarsening) of the wool tone, the specific weight of the based variety decreases: the yield of the latter in the runes of sheep of 56-50 qualities was 73.9%, in the runes of 48 qualities - 69.8%. Breeding groups of sheep of the desired type with a live weight of 55 ± 0.13 kg, with a shorn coat of 2.4 kg. In the process of breeding the breed's population, an array of animals adapted to the natural and climatic conditions of the regions has been developed, with good productive qualities, and further breeding of animals of this breed is aimed at improving competitive productivity indicators (meat and dairy productivity, which is gaining importance). without deterioration of the quality characteristics of wool. In general, the fecundity of the wool-meat "Kazakh type" of Qigai sheep is at the level of other wool-meat semi-fine sheep breeds.
