The study is to investigate the impact of fortifying Anabaena, a cyanobacteria, on castor leaves for nutritional studies. Anabaena is found in water and soil, having a potential to produce an elaborate array of secondary metabolites which shows metabolic effect on worms besides having antibiotic effect. In the present study, Anabaena at various aqueous concentrations was fortified and orally administrated to Samiacynthia, B. The results indicate that Eri silkworms fed with Anabaena variabilis at 500 ppm concentration showed improved larval weight (59.95%), pupation rate (31.83%), cocoon yield (146.88%), ERR (80.87%) and reduced larval mortality (75.60%) while other quantitative parameters were significantly high at 500 and 300 ppm concentrations when compared to control Data is collected and subjected to statistical analysis. It is evident that Anabaena variabilis is very efficient feed supplement in increasing the productive traits besides reducing the larval mortality in the Eri silkworm.
