家蚕豆腐渣人工饲料及五龄期饲育研究

Artificial diet mainly consisting of soybean bregs for silkworm ( Bombyxmori L.) and rearing of the fifth instar larvae with it

豆腐渣富含营养，用它配制的人工饲料理化性状优良，饲料成本可降低１５％～２１％．分别用含豆腐渣３５％和５０％两种饲料饲育五龄家蚕，结果表明，蚕体发育正常，豆腐渣３５％饲料区各项茧丝质成绩与对照相仿．生产的茧丝色泽好，丝色白，抗黄化能力强．研究认为豆腐渣是一种理想的人工饲料素材。

Soybean bregs which is produced from making soybean curd contains a lot of nutritious components. The artificial diet prepared mainly by soybean bregs powder presents good physical and chemical characteristics, and its cost is reduced by 15%～21%. Taking two kinds of diet which contains 35% and 50% of soybean bregs to rear the fifth instar larvae, results showed that the larvae could grow, cocoon and pupate normally; cocoon and silk performance of testing group fed on diet consisting of 35% soybean bregs parallels with the check group.Moreover, the cocoon and silk of the testing group have good quality, which color is especially white and yellowing by heating or UV Ray is lower. Therefore, soybean bregs is considered as a good material for making artificial diet. In the diet for current silkworm varieties, its suitable content is about 35%.
