The effect of vitamin C (L-ascorbic acid) on the some cocoom parameters and egg production of the silkworm (Bombyx mori L) were determined. Enriched mulberry leaves with vitamin C solution (0.2 g/liter) and water were fed to the forth and fifth instars larvae. Experimental groups were one, two or three times of the three feeding times per day and were substituted with treated leaves (with vitamin C solution of water). The male and female cocoom weight, cocoon shell weight and pupa weight were significantly increased (p<0.05) in all the experimental groups when compared with the control group. Egg productivity was significantly increased (p<0.05) in all the experimental groups except in three times feeding with vitamin C enriched mulberry leaves when compared with the control group. But, the male and female cocoon shell ratio is significantly increased (p<0.05) only in one time feeding with vitamin C enriched mulberry leaves group. Vitamin C content in mulberry leaves is enough growht and development of silkworm but donʹt completely available. Vitamin C availability was increased with supplementation of water.
