摘要： 为了保护地方猪品种，挖掘青海互助八眉猪生产性能。本试验以长白、大约克和白色杜洛克为父本青海互助八眉猪为母本，所产的二元母猪成熟后再与长白、大约克和白色杜洛克杂交，在此过程中对比研究不同杂交组合的二元母猪生长性能及繁殖性能。试验结果表明：长×八二元仔母猪的初生重、21日龄重均极显著高于其他两组(P<0.01)；长×八和白杜×八二元后备母猪乳头对数显著高于大×八组；2—4月龄长×八二元母猪生长性能极显著高于白杜×八组(P<0.01)；长×八组合的二元后备母猪的体长和胸围极显著高于白杜×八组和大×八组(P<0.01)；长×八二元母猪的繁殖性能和哺乳仔猪的生长性能均显著高于白杜×八和大八二元母猪(P<0.05)。

Abstract: To protect the local pig breeds and excavate the performance of Qinghai Huzhu Bamei’s production. This study recorded the growth and breeding performance of Qinghai Huzhu Bamei binary sows, which were hybrided by Landrace, Yorkshire and the White Duroc as male parent and Qinghai Huzhu Bamei as female parent, in the cross of Qinghai Huzhu Bamei binary sows and Landrace, Yorkshire and the White Duroc. The results showed that, the birth weight and 21-day weight of Landrace and Bamei binary Aberdeen sow were significantly higher than the other two groups (P<0.01); The gilts nipple logarithmic of Landrace and Bamei and White and Bamei Binary Sow were significantly higher than the Yorkshire and Bamei groups; the growth performance of 2-4 month-old Landrace and Bamei Binary Sow was significantly higher than the White Duroc and Bamei group (P<0.01); the length and bust of the Landrace and Bamei combinations of binary gilts were significantly higher than the other two groups(P<0.01)；the reproductive performance of Landrace and Bamei Binary Sow and the growth performance of piglets were significantly higher than the other two groups(P<0.05).
