摘要
本文研究了骨调素基因对苏钟猪和二花脸猪繁殖性能的影响。93头母猪660多窝产仔数记录被用来分析骨调素基因型与总产仔数和产活仔数的关系。结果表明,二花脸猪经产总产仔数基因型158/142和170/152、168/140之间差异显著(P<0.05),产活仔数基因型158/142和170/152之间差异显著(P<0.05)。苏钟猪头胎产活仔数基因型164/168和140/152、142/168、152/170之间差异显著(P<0.05),经产总产仔数基因型152/170和130/142之间差异显著(P<0.05)。
<Abstrcat> The effect of the osteopontin gene on reproductive traits in Suzhong and Erhualian pig lines was investigated. More than 660 litter records from 93 sows genotyped at osteopontin locus were analyzed to determine whether OPN gene influenced total number born (TNB) or number born alive (NBA). TNB between Erhualian sows with 158/142 and with 170/152 or 168/140 genotypes and NBA between 158/142 and 170/152 genotypes are significantly different in later parities (P<0.05). NBA between Suzhong sows with 164/168 and with 140/152, 142/168,152/170 genotypes is significantly different in first parity (P<(0.05)) and NBA between 152/170 and 130/142 genotypes is significantly different in later parities(P<(0.05).)
