The silkworm, Bombyx mori L. has been regarded as one of the most striking examples of monophagy as its food selection is very narrow and almost limited to mulberry leaves alone. B.mori obtain nutrients from the mulberry leaves for its sustained growth and development including cocoon production. However, in recent year, more efforts are made by researchers to enhance cocoon quality parameters by supplementing exogenous protein through diet. Such, an attempt has been made to record the influence of soyabean flour supplemented to mulberry leaf with different concentration viz., 2, 4 and 6% on the economic traits and aminotransferase activity in bivoltine CSR2 and CSR4 breeds. Moreover, the data revealed, significant increase in cocoon weight, shell weight, pupal weight and shell ratio at 4% concentration in CSR2 and 6 % concentration in CSR4. The aminotransferase enzyme activity level was higher at 4 and 6 % concentrations in CSR2 and CSR4, respectively.
