Abstract

The article presents material on the study of reproductive productivity of Kazakh fat-tailed sheep in the farms Tokan-1, Medkhan and Razakhun.  In November 2023, 950 ewes were cervically inseminated in three flocks with freshly obtained sperm from Kazakh black-tailed and foreign sheep. Sheep with natural sexual hunting were detected once a day in the morning from 6 to 7 o'clock with the help of sheep probes. Sperm from 11 main sheep was obtained using an artificial vagina.  Double cervical insemination was performed from 9 a.m. to 10 a.m. and from 4 p.m. to 5 p.m. Out of a total of 950 inseminated ewes, 868 heads were conceived on time. A total of 914 lambs were born, or an average of 104 lambs per 100 embracing queens. The birth weight of half-blooded dorper and precos lambs in Tokan-1 farms averaged 4.7±0.17 (n=96) and 5.0±0.19 (n=95) kg; Medkhan half-blooded dorpers 4.3±0.21kg (n=44). The KX "Razakhun" of half–blooded Australian whites is 4.8±0.25 (n=195) kg, respectively. The live weight of mongrel lambs at birth was slightly lower than that of control purebred fat-tailed lambs by 0.6-0.7 kg. In general, the lambs obtained had a strong constitution without signs of weakening. The average live weight at birth of control lambs was 5.1±0.21 kg in: Tokan-1 farm; Medkhan farm 4.9±0.22 kg; Razakhun farm 5.4±0.18 kg, respectively. The results of the lambing of Kazakh fat-tailed rough-haired sheep fertilized with sperm from foreign sheep breeds of Australian white Dorper and precos KH"Tokan-1 "Medkhan" and "Razakhun" are characterized by good indicators.
