家兔IGF1基因多態(tài)性與生長性狀的關(guān)聯(lián)分析
[Abstract]:The aim of this study was to investigate the relationship between the SNP of insulin-like growth factor 1 (insulin-like growth factor 1) gene and the growth traits of rabbits. The polymorphism of IGF1 gene exon in rabbits was detected by DNA pool and PCR-SSCP method. A SNP locus T365C was detected in exon 3 of the IGF1 gene in rabbits. The results showed that there were three genotypes: TT,TC and CC.IGF1 genes and their association with the growth traits of rabbits. The birth weight of TT genotype individuals in New Zealand rabbits was significantly higher than that of TC and CC genotype individuals at 28 days old (P0.05), while that of Belgian TT genotype individuals was significantly higher than that of 90 day old individuals and the average daily gain of birth to 90 days old individuals (P0.05). TC and CC genotype individuals (P0.05), the other varieties of growth traits did not reach the level of significance at this locus (P0.05). The results suggest that the IGF1 gene may be a major gene affecting the growth traits of rabbits or be linked to a major gene, and the T365C locus may be a molecular genetic marker to improve the growth traits of rabbits.
