The structure and physiological indicators of females of Kazakh coarse wool breeds of sheep differing on pigmentation level are of given in article. In the herd the specific weight of a female with the average level of pigmentation I made 54.14%, and intensively pigmented - 24.84% and weakly-pigmented - 21.02%. Sheep with intensive pigmentation showed resistance to temperatures and kept constancy of physiological indicators and on studying of influence of an ekzogormon(SZhK) on reproductive functions, growth and meat efficiency of Kazakh fat-Tailed coarse wool sheep. It is established that when using the foal serum of mares (SZM) on ewes of new Ordabasy fattailed coarse wool breed duration of heat of ewes increases that promotes in the first cycle of heat in dependence on age (3.5-5.5 years) to subject 87.8-97.2% of ewes to artificial insemination. Intensive 60-day autumn fattening of Kazakh fat-Tailed coarse wool lambs with use of natural pastures with additional top dressing and stimulation of growth of lambs an injection SZM (foal serum of mares) appeared an effective processing method of preparation the fat-Tailed lambs on meat the weight and an exit of meat, according to 12.1 kg and 43.1% to 18.3 kg and 47.5%.
