三元杂交F1代羊屠宰性能比较及CLPG基因遗传效应分析
Slaughter Performance Comparison of Three-way Cross F1 Sheep and Genetic Effect Analysis of the CLPG Gene
摘要
Abstract
In order to improve the meat production performance and economic benefits of sheep,this study set pure breeding group of small-tailed Han sheep as control,Australian white sheep,Dorper sheep and Charolais sheep as terminal male parent,and F1 hybrids of Australian White ×(Small-tailed)Han,Dorper × Han,and Charollais × Han as female parents to conduct a three-way crossbred test.The slaughter performance of 6 experimental groups(ADH,AXH,DAH,DXH,XAH,and XDH)and F1 small-tailed Han lambs were measured and compared,and the genetic effect of CLPG gene in F1 genera-tion sheep of three-way cross was analyzed.The results showed that under the same feeding conditions,the slaughter performance of AXH hybrid progeny(F1)was the best.The living weight,carcass weight,loin eye area,net meat weight and net meat rate of AXH hybrid progeny(F1)were significantly higher than those of small-tailed Han lambs(P＜0.01),and the living weight,carcass weight and loin eye area were significantly or extremely higher than those of ADH and DAH hybrid progeny(F1)(P＜0.05,P＜0.01).The genetic effect of CLPG gene in three-way crossbred hybrid progeny(F1)showed that the slaughter performance of individuals carrying T allele at g.232 C＞T locus was better than that of individu-als carrying C allele.The above results suggest that the hybridization advantage of AXH hybrid progeny(F1)is more obvious,and the T allele is beneficial to its muscle output.In production,AXH hybrid prog-eny(F1)carrying the T allele should be selected as far as possible for fattening.关键词
