波尔山羊、南江黄羊与土种山羊杂交效果比较

在贵州石阡县将波本F1、南本F1和本地羊分为三组，测定初生、2月龄、4月龄、6月龄、8月龄五阶段的体高、体长、胸围、管围和体质量。试验结果为：波尔山羊、南江黄羊杂交能显著提高贵州石阡当地山羊的产肉性能。其中波本F1初生重公羊提高67.57％，母羊提高67.65％。南本F1初生重公羊提高8.11％，母羊提高11.76％。6月龄波本F1公羊体质量提高25.19％，母羊提高26.19％。南本F1公羊和母羊体质量分别提高12.59％和16.67％。比较波本F1和南本F1各阶段体质量发现，除了2月龄和8月龄母羊的体质量波本F1比南本F1小外，其余波本F1都大于南本F1。尤其是初生重波本F1公羊比南本F1大1.1kg，增加了55.00％，母羊大0.95kg，增加了50.00％。并建立加强杂种羊的饲养管理。

Study on the Crossbreeding Improvements of Boer, Nanjiang Yellow and Guizhou Native Goat

The body weight(BW),body height(BH),body length(BL),heart girth(HG),cannon girth(CG)of the crossbred F 1 generation among Boer goat,Nanjiang Yellow goat with Guizhou native goats (BGF 1,NGF 1)were measured and compared with the native goat (GWG)in Shiqian conuty,Guizhou province.It was showed that BGF 1 could increase the birth weight,two month,four month,six month and eight month weight by 67.57%,41.18%,62.71%,25.19% and 40.41% for male,by 67.65%,28.39%,88.41%,26.19% and 13.89% for female,NGF 1 by 8.11%,35.29%,35.71%,12.59% and 31.82% for male,by 11.76%,31.82%,57.91%,16.67% and 24.31% for female respectively.BGF 1 male goat averaged 1.25kg,2.8kg,5.1kg,1.4kg and 5.9kg in birth weight,two month,four month,six month and eight month weight,female goat averaged 1.15kg,1.9kg,6.1kg,3.3kg and 2.0kg copared with GWG at the same age.The nutrition and management should be improved for the crossbred F 1 generation among Boer goat,Nanjiang Yellow goat with Guizhou native goat.
