Enhancement of cocoon yield in silkworm, Bombyx mori. L. by protein supplementation in shoot rearing

摘要

Two laboratory experiments were conducted during winter 2000 to study the effect of fortification of mulberry leaves and shoot with soyaflour on the larval and cocoon characters in a bivoltine race NB4D2 and a cross breed, PMXNB4D2 of silkworm, Bombyx mori. Soyaflour @ 5 g and 10 g kg~(-1) of shoot was compared with 10 g kg~(-1) of leaves.
