The demand for silk has been increasing day by day but the average silk production is not enough to meet its demand. In this study, we investigated the effect of amino acid supplemented mulberry feed on the biological and commercial traits of L. (Lepidoptera; Bombycidae). The silkworm larvae at 5th instar stage were taken and fed with fresh and healthy mulberry leaves coated with Alanine, Glycine and Serine in fourteen different combinations. Results of the current study revealed that the average weight of silkworm larvae and the % ratio of silk gland to body weight on day 7 was significantly (P˂0.05) higher in the group fed with amino acid fortified leaves as compared to the control. The commercial traits of larvae fed with amino acid fortified leaves also improved significantly. The larvae fed with Alanine (1 %) treated mulberry leaves showed the maximum cocoon weight, cocoon length, cocoon width, cocoon shell ratio and fibroin content as compared to the control group. It is evident from the results that the amino acid (particularly alanine) coated mulberry leaves have a positive effect on the commercial and biological traits of (L.).
对丝绸的需求日益增长，但丝绸的平均产量却不足以满足需求。在本研究中，我们调查了添加氨基酸的桑饲料对家蚕（鳞翅目；蚕蛾科）生物学和商业性状的影响。选取5龄期的家蚕幼虫，用涂有丙氨酸、甘氨酸和丝氨酸的14种不同组合的新鲜健康桑叶喂养。当前研究结果显示，与对照组相比，用添加氨基酸的桑叶喂养的组在第7天时家蚕幼虫的平均体重以及丝腺与体重的百分比显著更高（P˂0.05）。用添加氨基酸的桑叶喂养的幼虫的商业性状也显著改善。与对照组相比，用丙氨酸（1%）处理的桑叶喂养的幼虫茧重、茧长、茧宽、茧层率和丝素含量最高。结果表明，涂有氨基酸（特别是丙氨酸）的桑叶对家蚕的商业和生物学性状有积极影响。
