ResumoTo investigate the utilization of different carbohydrate sources and the possible substitution of carbohydrate for dietary protein for tilapia, Oreochromis niloticus×O. aureus, nine approximately isoenergetic purified diets were prepared. Three dietary protein levels (32, 28, 24%) were achieved by substitution with three levels (33, 37, 41%) and three sources (glucose, dextrin, starch) of dietary carbohydrate. Results indicated that fish fed starch or dextrin had significantly (P<0.05) higher weight gain and feed efficiency ratio (FER) than those fed glucose for all the protein levels with the exception of weight gain for the 24% protein level in which the difference was not significant. Fish fed starch and dextrin had similar weight gain in the 28% and 24% protein levels but were significantly (P 0.05) weight gain and FER, suggesting that starch or dextrin could spare some protein when the dietary protein level is low.
