abstract
The quality and quantity of food can play an important role in the growth and development of silkworm, particularly during larval stage which in turn influences the expression of cocoon productivity traits. In the present investigation, an attempt has been made to quantify the superiority of different feeding frequency (i.e. one time, two times, three times and four times per day) on the growth and development of bivoltine silkworm hybrid CSR26 × CSR27 for economic character expression. Observations were made for economically important traits of each stage viz., larval, cocoon and post cocoon filament length and denier) which indicated that feeding frequency of four times had significantly lesser larval duration (IV- 4:05, V-6:05) higher cocoon yield/10,000 larvae (by weight) (14.14), single cocoon weight (1.58), single shell weight (0.35), shell ratio percentage (21.99) and total filament length (788.67) closely followed by three times feeding frequency for larval duration (IV- 4:08, V-6:09), cocoon yield/10,000 larvae (by weight) (13.35), single cocoon weight (1.49), single shell weight (0.31), shell ratio percentage (21.24) and total filament length (724.33). Thus, based on per se performance values and significant difference values for important commercial traits these feeding frequencies can be easily utilized for commercial rearing without affecting the qualitative and quantitative economic characters.
