| Abstract | ||||
| A feeding experiment was conducted to evaluate the effect of olive pulp at different levels on growth performance, feed and nutrients utilization. body composition, plasma glucose, total plasma lipids (TPL) and total plasma proteins (TPP), liver enzymes and cost-benefit analysis ofNiletilapia fingerlings. Ten glass aquaria with the dimensions of 70x30x40 cm were used to stock 10 fish/aquarium averaging 9 g/fish. five experimental diets were formulated to contain 0. 5, 10.15 and 20% of Olive pulp instead of wheat milling by product. All the diets were isonitrogenous and isoenergitics. Fish fed 3-5% of body weight daily. The feed amount was given three times daily. six days a week for 77 days. Fish were weighed. biweekly and feed amounts were adjusted on the basis of the new fish weight. Results indicated that no significant differences (P>0.05) were observed in growth performance among all fish groups fed varied levels of olive pulp. Yet. there was a tendency of Nile tilapia fed 5% olive pulp to increase their body weight, gain and SGR. Lower amounts of feed intake were obtained when fish fed diets had 15 r 20% olive pulp. No significant differences (P>0.05) were observed in FCR, PER.
