摘要

Experiment was conducted to ascertain the effect of L-carnitine on growth and body composition of Cirrhinus mrigala fry (0.342 +/- 0.03 g) using five different concentrations (0.25, 0.50, 0.75, 1, and 0%) of L-carnitine-incorporated diets for 120 d. At the end of trial, weight gain, feed conversion efficiency, and protein efficiency of fishes fed with 0.25% L-carnitine diet were observed to be significantly higher. Poor growth was recorded in the fry fed diet with no carnitine, while intermediate growth was observed when fed with 0.50, 0.75, and 1% L-carnitine-incorporated diets. The analysis of body composition of C. mrigala fry indicated that there is no significant difference (P > 0.05) in moisture, protein, and ash contents, but significant difference (P < 0.05) was found in body lipid content of fry, fed with different concentrations of L-carnitine. Decrease in viscerosomatic and hepatosomatic indices were observed in fishes fed with L-carnitine-incorporated diets. Results of this study indicated that diet containing 0.25% L-carnitine can promote higher growth in C. mrigala fry.
