The present investigation was carried out to assess the rearing performance of silkworm Bombyx mori L. on antibiotic supplemented feed at various concentrations. The study was conducted on the silkworm breed APS-45. The worms were reared upto 3rd moult by feeding on mulberry leaves without any treatment. After 3rd moult, three replications were maintained and each treatment received different concentration of antibiotics. For each antibiotic three concentrations (0.05%, 0.10% and 0.15%) were prepared and sprayed on the mulberry leaves, a separate batch was also maintained where only distilled water was sprayed and that served as a control. Among the three antibiotics evaluated ceftiofur sodium showed best results followed by oxytetracycline and enroflaxcin. It was found that improved results were obtained with an increase in concentration of an antibiotic, ceftiofur sodium (0.15%) showed significantly improved results in economic parameters like cocoon characters, cocoon yield, average filament length, raw silk percentage and filament denier. So, present investigation reflected that antibiotics have the potential to be used for enhancing the cocoon and raw silk production.
