杜洛克猪 HMGA1基因多态位点与生长、饲料利用性状的关联分析
Study on HMGA1 Gene Polymorphism Site and Its Association with Feed Efficiency Related Traits in Duroc Pigs
摘要
Abstract
The objective of this study was to analyze two SNPs of HMGA1 gene,and investigate its association with feed efficiency related traits in Duroc populations.HMGA1 gene SNPs (g.-543 T>C and g.1356 C>T)in Large White pig and Min pig were detected by re-sequen-cing technology,SNP genotyping of g.-543 T>C and g.1356 C>T sites in Duroc populations were performed using Sequenom mass spectrometry,and the association of HMGA1 gene SNPs with growth and feed efficiency related traits in Duroc populations were analyzed.The results in- <br> dicated that the individuals of CT genotype in g.- 543 T > C increased 2.15 kg on 90 d body weight (P <0.05 ),decreased 3.21 d at 30 kg weight age (P <0.05 ),weaning weight was in-creased and 100 kg age were decreased,residual feed intake,30 to 100 kg average daily gain (ADG),40 to 90 kg average daily feed intake (ADFI)and 40 to 90 kg ADG were decreased,com-paring with CC individuals.Moreover the individuals of CC genotype in g.1356 C>T had signifi-cantly increased 90 d body weight (0.37 kg,P <0.05),ADFI (less 0.13 kg,P <0.05),back fat (BF,less 0.43 mm,P <0.05),RFI (less 70.40 g,P <0.05),30 kg age (less 0.56 d,P <0.05) and 40 to 90 kg ADFI (less 0.17 kg,P <0.05)were significantly decreased;Weaning weight and 100 kg age were increased;30 to 100 kg ADG,40 to 90 kg ADG were decreased than TT genotype individuals.And the CT genotype individual in g.1356 C>T had the similar results with CC gen-otype individuals that compared with TT genotype individuals.All in all,the two SNPs of HM-GA1 gene would be helpful in feed efficiency related traits in Duroc population.关键词
