Abstract :
A study was conducted to determine the effects of dietary vitamin C on growth performance, feed utilization
and carcass biochemical composition of Barbus sharpeyi fingerling. Five diets containing (0, 500, 1000, 1500
and 2000 mg kg-1) of ascorbic acid were fed to benni fingerlings (6.96±0.3 g) in triplicate tanks and twice
daily for a period of 56 days. The weight gain significantly increased (3.85 g) with enhanced feeding
supplementation levels up to 1000 mg kg-1 diet, but no further increase was observed in the experimental
treatments with feed supplementation levels, higher than 1000 mg kg-1. Feed conversion ratio was
significantly higher (P < 0.05) in fish fed with control diet. A general increase in protein efficiency ratio was
observed with increase in dietary vitamin C levels. Survival rate (%) did not display any significant
difference among the experimental treatments. The body protein content increased significantly with the
increase in dietary ascorbic acids levels. Fish fed diets containing 1000 mgkg-1 vitamin C exhibited
comparatively higher lipid content (P < 0.05). Although, hepatosomatic index (HSI) did not display any
significant difference among treatments, VSI of experimental fingerlings was significantly affected by
various ascorbic acids levels in the fed diet. Supplementation of vitamin C at 1000 mg kg-1diet enhanced the
growth performance and feed utilization of experimental fingerling of B. sharpeyi.
