Growth promoting effect of black gram and ground nut seed powder on Bombyx mori

Problem Statement: The silkworm requires certain essential sugar, proteins, amino acids, fatty acid, vitamins and micronutrients for its growth and higher production of good quality of silk. The low productivity is mainly due to low mulberry yield and poor quality of leaf mentioned that enrichment of mulberry leaves with supplementary compounds enhances the silk productivity. To evaluate the effect of mulberry leaves supplemented with ground nut powder and black gram powder mixture feeding the silkworm. Approach: The groundnut seed powder and Black gram power in different doses. This groundnut powder and black gram power separately sprayed on the leaves of the mulberry plant before feeding. Feeding started with 3rd instars larvae. Every day supplementation was given two times and for the other 3 times of feeding, mulberry leaves were alone given. Result: The ground nut treatment of (2%) food consumption (531mg/wt/animal/day) food absorption in higher (243mg/wt/animal/day) was observed 2% concentration. Approximate digestibility in higher (45.76) was observed 2% concentration. Efficiency of conversion of ingested food in higher (26.18mg/wt/animal/day)was observed. The results of the present study recommend supplementation of black gram and ground nut with mulberry leaf for feeding Bombyx mori. L. Conclusion: The results of the present investigation indicated that the Ground nut powder, blackgram powder and their mixtures have effect on the economic parameters of the silkworm, B. mori.
