The article presents current information on the microstructure of muscle tissue of aboriginal young sheep of the Volga region. The efficiency of lifetime formation of meat productivity and consumer properties of lamb from young sheep of the Bakur breed, sold in the year of birth, is estimated by the method of microstructural analysis. The method of morphometric assessment revealed the features of individual development of animals, conditioned by hereditary patterns and environmental conditions affecting the exchange processes, that ultimately changes the individual development of animals.
The article assesses the production method of young native sheep in the Volga region being sold in their birth year. Scientific and industrial studies were conducted to evaluate the effectiveness of the in vivo formation of meat productivity and consumer properties of mutton from young sheep of the Bakur breed. The results of the studies showed that the average live weight of Bakur sheep at birth is 3.9 kg. In the weaning time at the age of 4 months sheep weigh 27.5 kg, that is, the weight increased 7.1 times. The average daily weight increase in Bakur rams up to a month of age was 233 g; from a month to 2 months of age - 223 g; from 2 to 4 months of age - 165 g. The best morphological composition of carcasses belonged to young animals of 12 months of age, the ratio of meat to other tissues reached 80.8% and 17.2%. The content of tryptophan in lambs and young animals significantly exceeds the amount of oxyproline, which is a representative of defective proteins. Based on the above facts, the muscle tissue of the longest back muscle has a high commercial quality due to the thinnest muscle fibers with small impregnations of fat and is considered the most tender.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
