Description A 60-day feeding experiment was conducted
to evaluate the effects of dietary chromium (Cr) on
carbohydrate utilization and growth performance of
Labeo rohita fingerlings. Fishes were fed with four high
carbohydrate (53%), isonitrogenous (crude protein
35%), and isocaloric (415 Kcal, 100 gm−1
) experimental
diets containing different levels of dietary chromium
picolinate (Cr-Pic) viz.0, 400, 800, and 1200 μg kg−1
diet. Weight gain (WG%), specific growth rate (SGR),
feed efficiency ratio (FER), and protein efficiency
ratio (PER) were significantly increased at 800 μg
kg−1 diet chromium supplementation (P < 0.05). CrPic supplementation (800 μg kg−1
) also significantly
(P < 0.05) enhanced the protein: DNA ratio in muscle,
while DNA: RNA and DNA: tissue ratios were significantly (P < 0.05) decreased indicating higher
growth. Significantly higher amylase, protease, and
lipase activities were recorded in 800 μg Cr-Pic kg−1
diet fed fishes (P < 0.05), while any of the
experimental groups showing no significant (P >
0.05) change in hexokinase activity, indicating normal glycolysis in all. Furthermore, significant (P
