Reiationship of Phenolic Compounds In Mulberry Leaves To The Productivity of The Silkworm, Bombyx mori L.

Abstract

The present study aims to evaluate the nutritive values of five mulberry varieties used for feeding the silkworm, Bombyx mori L. larvae from the first till the 5th instar through studying their effect on biological, productive and biochemical changes, also through the related leaves consumed to the production of cocoon. Also, determining the phenolic content of these leaves and the antioxidant activities and their importance to the silkworm besides for further use of these leaves after the rearing season. The obtained results could be summarized as follow: I- Mulberry varieties. I.1-Chemical analysis of the examined mulberry leaves varieties. The mean moisture level of the leaves is higher in Kokuso-27 and the least moisture content was in Arandaly. Also, total protein content is relatively more in Sh2xlunlog comparing to the other varieties, while Kearyang-ppong was the highest in carbohydrate content and the least in Sh2xlunlog.
