abstract
Silk gland is the organ for synthesizing and secreting silk protein. This organ’s growth reflects ability of silk production, both in quality and quantity. The present study conducted to investigate the supplementary effect of spirulina on lipids and enzymes in salivary gland of silkworm, Bombyx mori (L.). The silkworm larva were fed with different concentrations (1, 3 and 5%) of spirulina. At the end of the experimental period, the silk gland was dissected out and weighed. Prepared silk gland homogenate was used for analysis of various biochemical parameters such as triglycerides, phospholipids, total lipids, protein and enzymes lipase and alkaline phosphatase activity. All the biochemical and enzymatic parameters were observed in positive correlation in 5% supplemented spirulina as compared with 1 and 3 % supplementation thus indicating the positive effect of spirulina due to enriched nutrient content.
