Effect of dietary protein level and vitamin c supplementation on performance of nile tilapia(oreochromis niloticus) [electronic resource].

Includes references.

Effects of varying dietary protein and vitamin C levels on several nutritional parameters were calculated for young Oreochromis niloticus. Live body weight of Nile tilapia (0. niloticus) increased significantly (P<0.001) with increasing dietary protein level or vitamin C; supplementation in fish diet. Average daily gain weight increased with 37.31% in fish fed the high protein diet (31.1% crude protein) than those fed the normal protein diet (25.4%). Also, average daily weight gain increased with 5.41 and 14.86%, respectively, in fish fed diets supplemented with 50 and 100 mg vitamin C/kg diet than those fed diets without supplementation.
