With the increase in the tourist flow in the Altai Mountains, the demand for lamb has increased, so methods are needed to improve the meat productivity of lambs. The article presents the results of a study of the influence of early mating of rams of the Prikatunsky meat-wool type on the productivity of their offspring under conditions of year-round grazing in the Altai Republic. According to the results of the productivity of the offspring, the breeding value of the producing sheep was determined. Experimental groups of queens and offspring were kept in the same flock, providing them with equal maintenance and feeding conditions — a method of maintaining queens and lambs year-round pasture maintenance followed by culling lambs at four months of age. According to the experiment results, the sheep of the second group are characterised by the best milk productivity with a high reliability of the difference. As a result, it was found that the age of the producer rams at the time of the first mating does not hurt the productivity of their offspring. In addition, it was found in the experiment that the descendants obtained from a younger ram differ in the best productivity indicators. Thus, by using sheep producers at an early age, it is possible to determine their breeding value one year earlier, which will significantly reduce the cost of their maintenance and, as a result, increase the profitability of the industry in private hands in peasant farms, personal subsidiary farms of citizens and individual enterprises.
