猪MYOG基因遗传多态性与胴体及肉质性状的相关性OA北大核心CSTPCD
Correlation of genetic polymorphisms of MYOG gene with carcass and meat quality traits in pigs
通过测定约 180 日龄的 8 个群体(梅山、大白、长白、大白×梅山F1代、梅山×大白F1代、长白×大白F1代、大白×长白F1代以及大白×梅山F2代)459头猪胴体性状、肉质性状以及肌细胞生成素基因(MYOG)多态性,分析MYOG在猪群体中的遗传效应.结果表明:MYOG在猪群体中呈现 3 种基因型,即AA、AB、BB;群体瘦肉率的提高与BB基因型显著相关,相较于AA与AB基因型,其提高幅度分别为 3.57%和 3.28%;在大白×梅山F2代群体中,MYOG的基因型与背最长肌pH值、股二头肌pH值呈显著相关;在大白×梅山F1代群体中,MYOG基因型与股二头肌大理石纹MM2呈显著相关.
This study investigated the genetic effects of myogenin gene(MYOG)polymorphism on carcass traits,meat quality traits,and muscle fiber characteristics by analyzing 459 pigs from eight populations at approximately 180 days of age(Meishan,Yorkshire,Landrace,Yorkshire×Meishan F1,Meishan×Yorkshire F1,Landrace×Yorkshire F1,Yorkshire×Landrace F1,and Yorkshire×Meishan F2).Results showed that MYOG exhibited 3 genotypes(AA,AB,BB)in the pig populations.An increase in lean meat percentage was significantly associated with the BB genotype,with increases of 3.57%and 3.28%compared to the AA and AB genotypes,respectively.In the Yorkshire×Meishan F2 population,MYOG genotype was significantly correlated with pH values of the eye muscle and biceps femoris muscle;while in the Yorkshire×Meishan F1 population,the genotype of MYOG was significantly correlated with marbling score(MM2)of biceps femoris muscle.
