Dietary niacin requirement of fingerling Indian major carp Catla catla Hamilton
A feeding trial was conducted to determine the dietary niacin requirement of fingerling Catla catla. Eight casein–gelatin based isonitrogenous (350 g/kg CP) and iso‐caloric (16.72 kJ/g GE) test diets with graded levels of niacin (0, 10, 20, 30, 40, 50, 60 and 70 mg/kg diet) were formulated and fed t...

RNA/DNA ratio also increased significantly (p < .05) as dietary niacin levels increased from 0 to 30 mg/kg, and thereafter remained unaffected with further inclusion of niacin. Blood indices including haematocrit (Hct), haemoglobin (Hb) and RBCs counts were significantly (p < .05) affected by varying levels of dietary niacin and also found to be highest in fish fed 30 mg/kg niacin.
