Abstract:
The association between various polymorphic variants of leptin gene and carcass traits were investigated by PCR-RFLP method in crossbred pigs. The 604 bp amplified PCR product was digested with Bam HI revealed restriction fragments 604 bp, 495 bp and 109 bp sizes for exon 2. The population in respect to various genotypes at exon 2 in crossbred pigs was not in equilibrium. The results of one-way ANOVA for dressing percentage, carcass length, loin eye area, Backfat thickness, belly girth and thigh girth showed non significance (p<0.05) in exon 2 locus of leptin gene except for heart girth which showed significance (p<0.05) Higher heart girth was observed for AB genotype which clearly indicates the superiority of AB genotypes than AA and BB genotypes.
