Live weight and body features of Ala-Too sheep

Relevance. Sheep farming is the main livestock sector in the Kyrgyz Republic and is developing quite rapidly in the Russian Federation. Significant public demand for mutton poses challenges for breeders to improve local coarse-wool sheep by increasing their precocity, robustness, meat and fat productivity, ability to earn a high feed price, and maximum production under pasture conditions.

Methodology. Research was conducted to determine the productivity of stud rams and ewes in the development of the Ala-Too sheep breed, which produces meat and fat. The research was conducted at the Tagai-Tilek breeding farm in the Suzak district of the Jalal-Abad region and the Ak-Kula breeding farm in the Kara-Suu district of the Osh region of the Kyrgyz Republic. Live weight dynamics and body condition indices were studied.

Results. The productive advantages of the Ala-Too sheep breed have been revealed. The average live weight of Hissar breeding rams was 95.5±2.14 kg, with a range of 85.6–103.7 kg, while that of local coarse-wool breeding rams was 61.4±2.64 kg, or 33.5% lower. The average live weight of local coarse-wool ewes was 55.3±0.41 kg, with a range of 52.3 to 59.4 kg. At birth, there were slight differences between the groups in the leg length index, bone content, and overgrowth of the rams. In terms of elongation and massiveness, ala-too sheep had higher rates — 71.2%, and local rough-haired sheep — 66.4%, or 4.8% less than ala-too sheep.
