SNP for regulating cortisol secretion level of Pig and use thereof

摘要

The present invention relates to a composition for determining a meat quality trait level of a pig, which comprises a preparation capable of detecting a single nucleotide polymorphism (SNP) of an intron region of an inositol-tetrakisphosphate 1-kinase (ITPK1) gene controlling the cortisol secretion level of a pig, A method for determining the level of meat quality traits of pigs, a method of producing pigs with increased level of meat quality of pigs, a method of lowering the level of cortisol secretion of pigs, meat quality of pigs, A haplotype marker for determining a trait level, and a microarray for judging a meat quality trait level of a pig including the haplotype marker. The haplotype marker of the present invention is a specific gene marker that determines the level of meat quality traits through the secretion amount of cortisol, which is a stress hormone secreted from pigs, and is used as a means of objectively evaluating the level of meat quality traits Therefore, it will contribute to establishing the order of distribution of pork meat.
