Abstract
The study was carried out in ZAO "New life" in Saratov region. The queens of the Stavropol breed of the local population were inseminated with sperm of halfbreed Australian meat merino of highly productive rams, and crossbred 1/4AMM + 3/4ST-blood offspring were received. Then these sheep were bred "in themselves". The productivity indicators of the offspring were studied at the age before a year and at 13-14 months. Then, reciprocal crossing of 1/4AMM + 3/4CT-blood hybrids with the main Stavropol breed was carried out and 1/8AMM + 7/8ST-blood-curled offspring was obtained, whose productivity indicators were studied at the age before a year and 13-14 months. The indicators of productivity were identified by consolidating the methods of selecting sheep in crossbreeding genetic group 1/8AMM + 7/8ST-blood, experimental data were analyzed and summarized when the local population of the Australian meat merino genotype was used on sheep of Stavropol breed. 1 /8-blooded by AMM bright Stavropol breed exceeded their purebred peers in live weight by 7.67% (P ≥ 0.999). In regards to unwashed wool, the superiority of brightly colored origin was 5.97% (P≥0.999), and in regards to pure wool, 1.46%. Wool with almost the same amount of mechanical impurities of hybrids less fatty (grease, respectively, 26.3% and 24.6%), has a lower indicator of iodine number of wool fat (respectively 21.9 and 20.5 units) and more light cream color. Thus, 1/8-blood mixed sheep of the Stavropol breed with the Australian meat merino at the age of 13-14 months as a result of consolidation of productivity indicators by the selection methods are characterized in comparison with purebred animals of the Stavropol breed with increased parameters of wool quality and live weight.
