摘要: 试验选用贵州白香猪作为母本,分别以大约克猪、杜洛克猪、长白猪作为父本进行杂交组合试验,测定了3个杂交组合F1代及对照组香猪的初生重、20日龄重及2~6月龄的生长发育指标。结果表明,初生重为杜×香>大×香>长×香>香猪,长×香组与对照组香猪间差异不显著(P>0.05);20日龄重为杜×香>大×香>长×香>香猪。生长发育各指标间差异显著,并且随着月龄增加各试验组间生长发育显著性增大,除2月龄体长为杜×香>大×香>长×香>香猪、3月龄体重,体长、胸围、腹围指标及5月龄体高、体长指标为大×香>长×香>杜×香>香猪外,其余月龄生长发育各指标为大×香>杜×香>长×香>香猪。

Abstract: Guizhou Bai Xiang pig was took as female parent, Yorkshire, Duroc and Landrace were took as male parents in the cross combination experiment in this study. Set Guizhou Bai Xiang pig as control group and birth weight, twenty days weight and 2 to 6 month’s growth and development indexes of 3 hybrid combination’s F1 and control group were determined. The results showed that the birth weight of Guizhou Bai Xiang pig cross experiment was Duroc×Xiang> Yorkshire×Xiang> Landrace×Xiang> Xiang pig, and there was no significant differences between landrace×Xiang and control group(P>0.05), and the twenty days weight was Duroc×Xiang> Yorkshire×Xiang> Landrace×Xiang> Xiang pig. The growth and development indexes were significant difference and more and more significant as month age increased, the trend was Yorkshire×Xiang> Duroc×Xiang> Landrace×Xiang> Xiang pig, except of the length of two months old was Duroc×Xiang>Yorkshire×Xiang> Landrace×Xiang> Xiang pig,and the weight, length, chest size and abdominal circumference of three months old and the weight and length of five months old was Yorkshire×Xiang > Landrace×Xiang> Duroc×Xiang> Xiang pig.
