[Correlation analysis between MC3R and MC4R gene polymorphism and growth traits in pigeon.].

Abstract

The SNPs in partial coding sequence of MC3R and MC4R genes were identified by polymerase chain reaction followed by single strand conformation polymorphism (PCR-SSCP) analysis and DNA sequencing in shack-Kee and Columba domestica from Harbin area. Correlation analysis between MC3R and MC4R polymorphism and growth and body composition traits was carried by the least square analysis. The genotypes of T91G mutation in MC3R gene and A903G mutation in MC4R gene proved to have significant association with body weight, carcass weight, and holo-carcass weight in shack-Kee (P<0.05). The interaction of MC3R-T91G and MC4R-A903G was discussed through combination genotype analysis. The least square analysis showed that the combined genotype had significant association with holo-carcass weight (P<0.05). Multiple comparisons revealed that BBAA genotype birds had a higher holo-carcass weight than AABB genotype birds and BBAA genotype was the beneficial genotype for the growth of body weight.
