Abstract
A 14-week feeding experiment was conducted in enclosure nets (each of 100 X 100 X 100 cm in diameter) in Merghem region from 1"t August to 15th November. Five isonitrogenous diets (22.75 % protein) with different levels of Kochie indica dried leafs and soft branches (KDLS) being 0, 15, 30, 45 and 60 % instead of the dietary protein were prepared and their effects on growth performance, feed utilization and carcass composition were evaluated for blue tilapia Oreocllromis aureus (11.5 g). Each of the experimental diets was fed to duplicate groups of fish at a feeding rate of 2.5 % of body weight. The results revealed that fish groups fed on the diet contained 15 % KDLS had significantly higher growth perfonnance and feed utilization compared to the fish fed on other KDLS substitution levels. Carcass composition affected with different KDLS substitution levels. Economically, with increasing the KDLS substitution level the cost of one Kg fish gain decreased. The study demonstrated that KDLS could replace 15 % of blue tilapia diet to improve growth perfonnance and feed utilization.
