title: [Relationship of growth hormone (GH 2) genotypes with some production performances in pig].
abstract: The genotypes of 117 Nanchang White pigs and 361 Large Yorkshire pigs at GH 2 locus were detected by PCR-RFLP. The PCR products were cut by Apa I, and produced two alleles: A(449 + 101 + 55 bp), and B(316 + 133 + 101 + 49 bp). Effects of different genotypes on some important production traits involving the birth weight, 2-month body weight, 6-month body weight, corrected back-fat thickness, average back-fat thickness, feed to gain ratio and lean percentage were analyzed. The results showed that in Nanchang White pigs, no significant differences were observed between different genotypes and different growth and carcass traits; while in Large Yorkshire, the pigs with BB genotype had more lean percentage than pigs with AA genotype (P < 0.05).
