摘要
对 5 6 0窝长白猪和 16 3窝杜洛克猪的产仔数分别以配种季节和胎次为二因子以及胎次、月份为单因子作统计分析 ,结果表明在长白猪群中胎次对其产仔数影响显著 ,配种季节以及配种季节与胎次互作对其产仔数影响不显著 ,月份对其产仔数的影响也不显著 ,在杜洛克猪群中 ,除配种季节与胎次互作对其产仔数影响显著外 。
Double-factor (mating season+litter number) and single-factor (mating month or litter number) statistical analysis were carried out on the litter size traits of 560 litters landrace pigs and 163 litters Duroc pigs, the results showed that the litter number has a statistical significant effect on the litter size performance of landrace pigs, but the effect of mating season and the effect of interaction between mating season and litter number were not at the significant level. The results were the same in the Duroc population except that the effect of interaction between mating season and litter number on the litter size performance was statistically significant.
