Annotation. Purpose: The purpose of the presented research is to establish the influence of natural pastures of the arid zone of the Volgograd region on the formation of meat productivity of rams of different types of edilbay breed. Methodology: The studies were carried out using modern mathematical-statistical methods for processing experimental data. Concrete recommendations are given to increase the production of mutton received from sheep of the edilbay breed and to improve its quality indicators. Results: Experimental studies continued for 10 months. For the entire period of the experiment, in terms of body weight, the rams of the new type (78.50 kg) were larger than the animals of the original type (74.20 kg) by 4.3 kg, or 5.79%. Amino acid analysis of the longest muscle of the back of experimental rams showed that the total amount of amino acids contained in mutton obtained from animals of the new type, irreplaceable, was 8.08%, which is higher compared to the analogs of the initial type by 0.47%. According to the content of replaceable amino acids in mutton, the same tendency was observed for the superiority of mutton obtained from animals of a new type as compared to the original type. A comparative study of the chemical composition of mutton has shown that animals of a new type exceed the indicators of the original type in calcium content (Ca) by 3.64 μg / g; iron (Fe) at 1.32 μg / g; iodine (I) at 0.04 μg / g; potassium (K) at 140 μg / g; manganese (Mg) at 14 μg / g; selenium (Se) at 0.02 μg / g. Recommendations: The experimental work carried out has shown that animals of a new type not only increase their live weight faster, but also accumulate much more elements entering the body, and also increase the nutritional value of mutton due to a higher accumulation of amino acids in its structure. Therefore, in the future, in order to increase the production of mutton and improve its quality, it is necessary to use animals of the Edilbay breed of a new type.
