宁夏西门塔尔杂种牛UCP2基因多态性及其与生长性状的关联性分析
Correlation Analysis between UCP2 Gene and Growth Traits in Ningxia Hibrid Simmental Cattle
摘要
Abstract
To find genotype with fast growth rates in Ningxia hibrid Simmental cattle,the genetic variation of UCP 2 gene were detected by PCR-SSCP method and DNA sequencing,then analyzed UCP 2 gene polymorphism related with some growth traits.The results showed that there were three SNPs (T632C,A655G and A689C)in UCP2 gene exon 1,which divided into AA,BB and AB genotypes by PCR-SSCP method.Individuals with different genotypes in different months of age,body weight,body height,chest circumference and body length were AA>AB>BB.AA gen-otype in different age of body height and chest circumference were significantly different than BB genotype (P<0.05;P<0.01),and were no significant difference with AB genotype (P>0.05). The results demonstrated that T632C locus had significant meaning for improving weight trait breeding of Ningxia hibrid Simmental cattle,AA genotype could be the breeding genotype.关键词
