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

Seven microsatellite DNA markers on chromosome 6 and USDA2.6 piggenetic linkage map were used for interval QTL mapping. The results revealed that at theposition of 38-41 cM there was a chromosome-wide highly significant QTL affecting carcassbackfat A thickness (P < 0.01), which was closely linked with MN007 and the ratio of QTL addi-tive variance to F2 phenotypic variance was 5.90%. At the position of 60-70 cM there were twochromosome-wide significant QTLs affecting carcass lean percentage (P < 0.01) and skin and fatpercentage (P < 0.05), which were closely linked with MN003 and the ratio of QTL additivevariance to F2 phenotypic variance were 18.44 and 3.75%, respectively. At the same position,there was a single-point QTL also closely linked with MN003 and highly significantly (P < 0.01)affecting carcass lean. In addition, there were two chromosome-wide highly significant (P < 0.01)QTLs affecting meat color and marbling, which were closely linked with MN13 at the positionof 70-75 cM and the ratio of QTL additive variance to F2 phenotypic variance were 14.05and 1.77%, respectively.展开更多
