Polymorphism of Genes and Their Impact on Beef Quality

The single-nucleotide polymorphism (SNP) form of genes is a valuable source of information regarding their suitability for use as specific markers of desirable traits in beef cattle breeding. For several decades, breeding work focused on improving production efficiency through optimizing the feed conversion ratio and improving daily gains and meat quality. Many research teams previously undertook research work on single-nucleotide polymorphism in myostatin (MSTN), thyroglobulin (TG), calpain (CAPN), and calpastatin (CAST) proteins. The literature review focuses on the most frequently addressed issues concerning these genes in beef cattle production and points to a number of relevant studies on the genes' polymorphic forms. The four genes presented are worth considering during breeding work as a set of genes that can positively influence productivity and production quality.

Automated summary

The SNP form of genes provides valuable information for assessing their suitability as specific markers for desirable traits in beef cattle breeding. Previous research has focused on SNP in myostatin, thyroglobulin, calpain, and calpastatin proteins. The literature review highlights the importance of these genes in beef cattle production and suggests their potential to positively influence productivity and production quality.
