摘　　要：通过研究担桑产茧量、茧重和茧层量饲料效率,探讨四川省首对细纤度三眠蚕品种“蜀细1号”与四眠蚕的饲料效率的差异。试验结果表明,“蜀细1号”食下1 kg桑叶的产茧量为58.72 g,比四眠蚕的产茧量高20.72%。“蜀细1号”的茧重饲料效率为5.83%,茧层饲料效率为1.25%,分别比四眠蚕高33.11%,26.26%。以上研究为三眠蚕品种“蜀细1号”的推广应用提供了科学依据。The cocoon production of mulberry and the feed efficiency of the cocoon weight and cocoon shell weight were studied to explore the differences of feed efficiency for the first pair of fine size trimolter race "Shuxi 1" in Sichuan Province and the four-molter race. The results showed that the cocoon production of "Shuxi 1" was 58.72 g after eating of 1 kg of mulberry leaves, which was 20.72% higher than the cocoon production of the four-molter race. The feed efficiency of "Shuxi 1" was 5.83%, and the feed efficiency of the cocoon shell weight was 1.25%, which was 33.11% and 26.26% higher than that of the four-molter race, respectively. This study provides a scientific basis for the popularization and application of the trimolter race "Shuxi 1".
