4 DNA marker of adipocyte-fatty acid binding protein gene related the intramuscular fat content in beef cattle

摘要

The invention of key economic traits of beef meat, especially the DNA markers involved in the excavation intramuscular fat, relates, predict the genetic qualities that govern the beef carcass traits and the development of DNA markers to determine gihayeo improve the accuracy of early selection and evaluation object is to provide improved and beef. ; The invention, the fatty acid binding protein is expressed in fat cells that act in the body of animals, leading to structural changes in the fatty acid through the coupling with the free fatty acids in the form of triglyceride in fat cells to pass (fatty acid binding protein, FABP4) encryption 17 genes were excavated gujobyeon This (Single nucleotide polymorphism) in the gene, mutations of the three loci naemeurosseo dual structure exists independently of each other through the statistical analysis revealed that having a significant impact on each of intramuscular fat, beef, beef was used in the selection of an object can be utilized for improvement and gogeupyuk and beef production.
