Abstract

Silk production basically depends on the Bombyxmori L. larval protein metabolism which in turn needs
more energy generating events, spinning requires more muscular activity and silk is being produced by the
silk gland. The quality of the leaves has a profound superiority of silk produced by the B.mori
(Priyadharshini et al., 2008). Probiotics are organisms and substances which contribute to intestinal
microbial balance(Parker, 1974).The present study highlights the effect of sporlacs upplements on the
biochemical parameters of silkworm B. mori. The total soluble protein was estimated by following
standard procedure (Lowry et al., 1951) with bovine serum albumin as the standard protein. The total
protein content in the different parts of larvae increased when the larvae was treated with increased
concentration of sporlac. Highest protein content was observed in the silk gland of larvae treated with 5%
sporlac (32.44±0.03 mg/dl) and minimum protein content (13.03±0.03 mg/dl) was observed in haemolymph
of silkworm treated with 1% sporlac
