蚕用营养饲料在广西蚕业应用研究初报

用山东农业大学蚕学系研制的新型蚕用营养饲料在正常情况下让5龄蚕添食,研究其对家蚕产茧量、丝质和饲料效率的影响。结果显示,添食营养饲料区与添食清水对照区相比,死笼率降低2.80个百分点,虫蛹统一生命率提高3.31个百分点,蚕茧产量提高1.32%,节省桑叶20.24%,蚕茧生产效率提高14.19个百分点,茧层生产效率提高3.24个百分点,上车茧率提高4.70个百分点,一茧丝长提高4.70%。表明该蚕用营养饲料具有增强蚕儿体质,减少蚕病发生,提高产量,节省桑叶,提高蚕茧生产效率,提高茧丝质的作用。

Preliminary studies on the application of nutritious feed for silkworm in Guangxi sericulture industry

The fifth instar larva were fed with a new type silkworm nutritious feed which was produced by Shandong Agricultural University under normal condition,to study its effects on the yield,silk quality and feeding efficiency of silkworm.The results showed that as compared to the control of adding water,the rate of dead worm cocoons of adding feed decreased by 2.80 percent point,the larva-pupa survival rate increased by 3.31 percent point,the yield of cocoon increased by 1.32% and mulberry leaves was saved by 20.24%,the production efficiency of cocoon increased by 14.19 percent point,the production efficiency of cocoon shell increased by 3.24 percent point,reelable cocoon increased by 4.70 percent point,and single cocoon filament length increased 4.70%.It indicated this silkworm nutritious feed could improve the silkworm physique,decrease silkworm disease,increase cocoon yield,and save mulberry leaf,resulting in higher production efficiency of cocoon and better quality of cocoon filament.
