Role of Food Additives on Young Age Silkworm (Bombyxmori .L) Rearing

The overall development of silkworm larvae depends on getting the required food which can be easily digested and assimilated in the body tissues properly for the silk synthesis. Keeping this in view, an attempt has been made to increase the growth of young silkworm Bombyx mori. This is ensured through supplementation of food additives, intern biochemical constituents of worm. The results of the experiment revealed that, food additives were found effective in increasing the protein, carbohydrate and lipid content in Chawki worms. Among silkworm hybrids viz, (PM x CSR2, CSR2 xCSR4, APM1 x APS8, APM2 x APS12 and (CSR6 x CSR26) x (CSR2 x CSR27)), the highest protein content of 19.91mg, 21.44mg, 19.83mg, 19.71mg and 24.03mg was recorded on soya flour dusted batches @ 10g/kg of leaves respectively, compare to control (17.63mg, 18.02mg,17.58mg, 17.51mg and 22.72mg). The same trend was noticed in lipid content of all the hybrids. Further it is very much reflected that, even the highest carbohydrate content in the body of young silkworm was recorded on supplementation of corn flour @ 10g / kg of leaves followed by corn flour 5g / kg of leaves in all the silkworm breeds.
