The polymorphisms of heart fatty acid binding protein gene (H-FABP) were detected by PCR-RFLP. The effects of different H-FABP genotypes were analyzed by a fixed model. The results showed that, the carcass composition traits were affected by H-FABP gene significantly, backfat thickness alive, carcass backfat thickness between 6th - 7th rib, and average carcass backfat thickness, of different H-FABP genotypes were significantly different (P<0. 05). The dominant effects on the traits demonstrated that the gene affected the carcass composition traits overdominantly. The results also showed that H-FABP gene affected the growth traits and meat quality traits, and the pH, of different H-FABP genotypes was significantly different.展开更多
