Berkshire Pigs

The paraoxonase (Pon) gene family contains three members: Pon1, Pon2, and Pon3. Pon3 modulates superoxide production and prevents apoptosis. The role of Pon3 has not been fully elucidated in the pig. This study is the first to investigate the association between Pon3 and meat quality in the Berkshire pig. We identified a single nucleotide polymorphism in the Pon3 gene (c.227A > G) that resulted in a change in histidine to arginine at position 76. To elucidate the role of this non-synonymous single nucleotide polymorphism in the Pon3 gene, we analysed the Pon3 genotype and meat quality traits in 434 Berkshire pigs. The results of a codominant model show that carcass weight, meat colour (lightness), cooking loss, and the Warner–Bratzler shear force were significantly associated with the Pon3 genotype. Furthermore, the 24-h post-mortem pH had the strongest relationship with the Pon3 genotype. The G allele decreased cooking loss and fat content, whereas the A allele increased the 24-h post-mortem pH and decreased backfat thickness, which contribute to meat storage life and M. longissimus dorsi depth respectively. In conclusion, the non-synonymous single nucleotide polymorphism in the Pon3 gene showed a close correlation with meat quality traits in the Berkshire pig.

Abstract The purpose of this research was to investigate the effect of the POU1F1 gene on meat quality traits in the Hyla, Champagne, and Tianfu Black rabbit breeds. We detected one single nucleotide polymorphism and the SNP was located at 536 bp in intron 5 of this gene. Chi-square tests showed that the genotypic frequencies in the three rabbit populations were not in Hardy-Weinberg equilibrium. The PIC values indicated that the three populations had intermediate levels of genetic diversity. Rabbits with the CC genotype had a significantly greater pH0h than those with the CT genotype in the biceps femoris muscle. The least squares means for cooking loss in CT and CC rabbits were significantly higher than those for TT rabbits. Rabbits with the CC genotype had a significantly higher intramuscular fat content in the longissimus dorsi and biceps femoris muscles than those with genotype TT and CT. Thus, the results here indicate that this POU1F1 SNP may be of potential use in marker assisted selection for meat quality traits in rabbits.
