In the present investigation, experiment trial was conducted on food rationing to check the impact on quantitative and qualitative parameters. The effect of feeding was evaluated by rearing the silkworms with four different treatments viz. One feeding (24 hrs - gap), Two feeding (12 hrs - gap), Three feeding (8 hrs - gap) and Four feeding (5 hrs - gap). The experiment concluded that, there is significant differences were observed among all the treatments with respect to pre and post cocoon parameters towards silkworm growth and development. The total larval duration was recorded more in T1 i.e. 28 days and less in T4 i.e. 25 days. The larval weight was observed significantly more in T4 i.e. 49.33 g and less in T1 i.e. 34 g, whereas ERR/10000 larvae was differed with 4200 & 8466.33 by number and 4.73 Kg & 16 Kg by weight was observed in T1 and T4 respectively with significant differences among all the treatments. The average filament length of T1 is 505.67 mtr and T4 is 941.67 mtr with raw silk percentage 25.74 and 32.48 per cent respectively. The defective cocoon percentage was more in T1 i.e. 9.42 and less in T4 i.e. 4.47 per cent. The above observation shows importance of food rationing to the silkworm at different intervals for their growth &development and cocoon productivity.
