title: Distribution of the frequency of occurrence of alleles by the calpastatin gene in sheep of different breeds (review)
abstract: The genetic diversity of modern populations of domestic animals is very important for improving breeds, for their adaptation to various environmental conditions, as well as for obtaining high-quality livestock products, in particular meat. The calpastatin gene (CAST) is considered as one of the promising markers of growth intensity and meat quality. The article presents an analysis of the literature review on the CAST gene in sheep from the following countries: Asia, New Zealand, Iran, England,
