摘　　要：为了测定三系母猪的配合力,在桂粤怀集公司闸岗猪场,以W51、W52、W61和W62杂交生产4种组合的杂交母猪W211、W212、W351和W352,比较4种杂交母猪的生长发育、胴体性能和体型外貌,并以S122系公猪与以上4种杂交母猪配种,比较几种组合的繁殖性能。结果表明,不同杂交母猪的体型外貌有一定差异。W211系猪体长偏短,乳头数偏少,背膘薄,生长速度中等;W212系猪体长中等,有效乳头数较多,生长速度较快,背膘偏厚;W351系猪体长较长,有效乳头数偏少,背膘中等,生长速度偏慢;W352系猪体长最长,有效乳头数较多,生长速度较快,背膘中等。W352系猪在总产仔数、产活仔数、产健仔数和21日龄窝重等繁殖性状指标上具有较明显的优势,其配套组合的杂种优势率也较高。4种不同类型杂交母猪中,W352系猪体型高长,繁殖性能优势明显。In order to determinate combining ability of three-line hybrid sows,we compared growth performance,carcass performance and body conformation of four kinds of hybrid sows,including W211,W212,W351 and W352 which were produced by W51,W52,W61 and W62 lines,and four kinds of hybrid sows were mated with the S122 boar to produce commercial pigs in Zhagang pig farm of Huaiji branch of Guiyue company.The reproductive performance of different hybrid sows were compared.The results showed that there were some differences among them in terms of body conformation.The body length of W211 pig was short,teat number was less,back fat was thin and growth rate was medium.The effective teat number of W212 pig was more,body length was medium,back fat was thicker and growth rate was faster.The effective teat number of W351 pig was less,body length was longer,back fat was medium and growth rate was slower.The body length of W352 pig was the longest,effective teat number was more,back fat was medium and growth rate was faster.W352 sows had obvious advantages in terms of total litter size,number born alive,number born robust,and litter weight at the age of 21 days,and the heterosis rate of its hybrid combination was higher.Among four kinds of hybrid sows,W352 pig had a longer body length with obvious advantages of reproductive performance.
