Abstract
Spirulina is a blue-green microalgae. It contains 18 amino acids and vital vitamins like Biotin, Tocopherol, Thiamine, Riboflavin, Niacin, Folic acid, Pyrodozoic acid, Beta-carotene and Vitamin B12 etc. These nutrients are very easy to digest Protein (biliprotein) & Carbohydrates. Other different minerals and trace minerals, Beta-carotene, Chlorophyll, GLA Omega-3 fatty acid are also found in Spirulina. For this study we have conducted the experiments to know the effect of Spirulina (with different Concentration &dosages) on the rearing performance of Eri-silkworm Philosamia ricini.We have grouped the worms along with their control and then the experimental groups were treated with the different dosages of Spirulina specially to find the effect on the larval and cocoon parameter (Larval length, Larval weight). Then the collected datas were subjected to statistical analysis .All the results were found significant.
