Abstract
Sheep farming plays a vital role in ensuring the country’s food security, especially in regions with traditional pasture management, such as the Republic of Kalmykia. Given the growing demand for meat products, increasing the biological value of lamb through industrial crossbreeding is particularly important. This article examines the amino acid composition of the meat of crossbreeds produced by crossing Kalmyk fat-tailed sheep and Dorper × Kalmyk crossbreeds with Charolais rams. The experiment was conducted at the experimental farm of the Kalmyk Research Institute of Agriculture (2021-2024). The results showed that three-breed crossbreeds (½Sh × ¼Dp × ¼KKr) outperform their two-breed peers in the total content of essential and nonessential amino acids in meat by 19.6% (p < 0.0001) and 22.2% (p < 0.0001), respectively. The high tryptophan content in three-breed crossbreeds (193.29 mg/100 g) indicates an increase in the quality of meat protein.
