Results of late age silkworm feeding by mulberry branchs
Mulberry harvest by branch cutting method may reduce labour cost as compared to gather mulberry leaves. Thus, mulberry harvest by branch cutting is a growing tendency. This paper showed the effect of feeding mulberry branch to late age silkworms and their cocoon. Cocoon yield and quality of late age silkworm eating branch mulberry on the bamboo tray and on the floor are equal or higher than eating leaf mulberry with the same feeding times. Cocoon yield and quality of silkworm feeding by mulberry branchs on the floor is better than on the bamboo tray. Cocoon yield of late age silkworm feeding by mulberry branchs on the floor is higher 6.63%, quality cocoon ratio higher 2.08% than the control experiment. The most outstanding is feeding three times per day with silkworm rearing on the floor and four times per day with silkworm rearing on the bamboo tray. However, it is necessary to pay attention during rearing bed cleaning in order to avoid silkworm loss.
