Biological usefulness of muscle tissue of young sheep of Romanov breed

Sheep farming plays a major role in increasing meat production. Sheep have a complex set of economic and biological characteristics that dictate their breeding in various natural and climatic zones. Selecting the right breed is essential for the effective development of sheep farming.
The experimental portion of the study was conducted at the “Glava Lunin A.M.” peasant farm in the Orenburg Region. The article presents the results of age-specific determinations of tryptophan and hydroxyproline content, as well as protein quality indicators, in the muscle tissue of Romanov rams (Group I), wethers (Group II), and ewes (Group III). It was found that, due to sexual dimorphism, the muscle tissue of the rams was characterized by higher tryptophan content and protein quality indicators. No intergroup differences were observed in hydroxyproline content. When slaughtering young Romanov sheep, meat products were obtained that were distinguished by a fairly high biological value; ram lambs had a higher concentration of tryptophan in meat and the value of its BCP, ewes had the lowest, and wether lambs occupied an intermediate position.
