Abstract


Sericulture plays a major role in rural employment, poverty alleviation and earning foreign exchange. A lot of entrepreneurial opportunities are available in various areas of sericulture. The quality of mulberry leaves fed to the silk worms is considered to be the prime factor for good cocoon and crop production. To find out the food efficacy of silkworm larvae fed with silver nanoparticles of Rosa rubiginosa treated with mulberry leaves. The silver nanoparticles were synthesized by chemical reduction method .The fifth instar larvae were selected for our study. Fiftth instar of silkworm larvae, Bombyx mori L. were fed on mulberry leaves fortified with Rosa rubiginosa silver nanoparticle extract at certain concentrations. The impact of the food efficacy factors such as, Food Consumption, Food Assimilation, Approximate Food Digestibility, Food Consumption Index and Coefficient of Food Utilization were examined. Different results were obtained depending upon on the various concentrations used. Almost in all the experimental concentrations of Rosa rubiginosa silver nanoparticle increased feed efficacy than control without any supplementation. And there is a little elevation observed in 1% concentration. Thus, supplementation of mulberry leaves with Rosa rubiginosa silver nanoparticle enhance feed efficacy, subsequently, enhancing the commercial qualities of cocoon. Thus it may be beneficial to the farmers and entrepreneurs in silk production.
