Abstract: The nutritive value of mulberry leaves has a direct influence on various economic parameters of the silkworm including the quality of cocoon and silk derived from it. The mulberry leaves enriched with additional nutritional supplements have often proved to be beneficial in the production of better cocoons and silk yield. The present investigation was undertaken to know the effect of mulberry leaves enrichment with combinations of various nutritional supplements viz., vitamin C, vitamin B-complex, soya flour, methionine and L-serine on economic characters in FC₁X FC₂ silkworm hybrid. The result of the study revealed that marked improvement in the economic parameters such as single cocoon weight, single shell weight, cocoon shell ratio, ERR by number, ERR by weight, filament length, filament weight and denier when the FC₁X FC₂ silkworm larvae reared on vitamin C 0.25% + soya flour 0.25% + vitamin B-complex 0.5% + methionine 0.5% over control batches.
