FOOD INGESTION, DIGESTION AND CONVERSION PATTERN OF NEW BIVOLTINE HYBRID SILKWORM, BOMBYX MORI L.

Nutritional and feed conversion efficiency parameters of newly evolved race (CSR 16 x CSR 17) were studied. Nutritional indices parameters like ingesta digesta. approximate digestibility. reference ratio and consumption index were recorded significantly less in CSR 16 X CSR 17 when compared with control (CSR2 CSR4). Nutritional efficiency parameters like efficiency of ingested and digested food into larvae, cocoon and shell were recorded significantly higher in CSR 16 X CSR17. Ingesta and digesta required to produce one gram of larvae, cocoon and shell were recorded significantly higher in CSR2 x CSR4 when compared with CSR 16 × CSR 17.
