Abstract: The effect of Supplementation of food especially Spirulina on food intake and utilization was studied in Cross Breed race of Silkworm Bombyx mori (Linnaeus) in IV and V instar larvae, when fed with ad libitum Mulberry leaves Morus alba treated with three different concentrations of food Spirulina at 26⁰±2⁰C with a relative humidity of 80±10%. The food utilization parameters like food intake, feces defecation, assimilation, food converted, oxidation, feeding rate, assimilation rate, conversion rate, metabolic rate, assimilation efficiency, conversion efficiency (K1 and K2) were studied. It has been observed that the 2% Spirulina treated group plays a significant role with an increase in growth and better food intake which averages 14422.41 mg/mg/day compared to control group i.e., 3185.366 mg/mg/day and also other two Spirulina treated groups i.e., 1% and 1.5% concentrations.
