Research Abstract

Correlation between dietary nitrogen efficiency and growth of the silkworm, Bombyx mori were investigated. 1) The effects of dietary levels of protein and vitamin B6(B6) on growth and nitrogen efficiency were studied. B6 content of diet affected not only the growth and silk production but the utilization of the diet. It was clarified that higher dose of B6 brought to an improvement of efficiency of dietary nitrogen. 2) The minimum level of digested protein required for larval molting and ecdysteroid level of larval haemolymph were determined. Ecdysteroid titer increased when the digested protein exceeded 18mg per larva during 4th instar, and when the protein amount exceeded 19mg, the larva molted. 3) Relationship between diet digested and the respiration was studied. According to the respiratory quotient, it was estimated that the larvae utilize carbohydrate,fat and protein as repiratory substrates at a ratio of 7:2:1.
