Administration of blue green algae Spirulina meneghiniana on the Morus alba leaves to enhanced growth rate and economic traits of silkworm

Blue-green algae Spirulina meneghiniana is one of the most popular microalgae that was found to be mostly protein. It includes amino acids, vitamins, protein, carbohydrates, minerals and trace minerals, omega 3 fatty acid, beta-carotene, chlorophyll, and many other nutrients. The mulberry leaves fortified with different concentrations of blue green algae S. meneghiniana extracts were given to silkworm larvae from 3rd instar onwards once a day. A significant increase in growth rate, silk gland ratio, cocoon weight, pupal weight, shell weight, shell ratio, filament length and fibroin percentage denier was observed.
