摘　　要：[目的]提高湖羊羔羊的甲级羔皮率。[方法]将湖羊怀孕母羊分为2组,试验组在母羊怀孕后期进行限饲,对照组按照常规方法饲养,探讨提高湖羊羔羊的甲级羔皮率的方法。[结果]试验组羔羊甲级羔皮率达42.43%,羔羊荐部伸直毛长1.90 cm,被毛的紧贴度达43.63%。对照组羔羊甲级羔皮率为22.59%,羔羊荐部伸直毛长2.08 cm,被毛的紧贴度为24.82%。[结论]在湖羊母羊怀孕后期限制营养供给,可改善湖羊羔羊羔皮品质,提高甲级羔皮率。[Objective] The research aimed to increase the first-class lambskin rate of Hu Sheep lambs. [Method]The pregnant ewes of Hu Sheep were divided into two groups（experimental group and control group）. The feed of ewes in experimental group in late pregnant stage was restricted. And the ewes were fed according to the conventional method. The method of increasing the first-class lambskin rate of Hu Sheep lambs was discussed. [Result] In experimental group,the first-class lambskin rate of Hu Sheep lambs was 42. 43%,the straight length of wool in sacral regions was 1. 90 cm and the wool close degree reached 43. 63%. In control group,first-class lambskin rate of Hu Sheep lambs was 22. 59%,the straight length of wool in sacral regions was 2. 08 cm and wool close degree was 24. 82%. [Conclusion]Restricting the nutrition supply of ewes could improve the lambskin quality and increase the first-class lambskin rate of Hu Sheep lambs.
