Influence of some polymorphic genes on meat productivity and meat quality of cattle (review)

Summary. The article provides an overview of foreign and domestic researches on study of polymorphisms of candidate genes that determine meat and milk productivity, quality of cattle meat: LEP, CAPN1, CAST, DGAT1, FABP4, RORC, SCD, 1СSN3, PRL, BLG, TNF-α and others. The use of informative data of DNA markers allows selection at an early age, and also characterizes the polygenic nature of inheritance. The choice of genetic markers depends on the frequency distribution of genes, genetic distance between breeds and the presence of particular alleles. Nowadays, selection based on DNA markers of beef cattle productivity has begun to be introduced into the practice of selection and breeding work. Analysis of the genetic diversity of ecological and genetic groups using erythrocyte antigenic factors and DNA markers will provide objective control over selection process and determine its further direction.

Key words: cattle, selection, single nucleotide polymorphism, DNA markers, meat productivity, meat quality.
