| Abstract |
This study was designed to determine the effect of partially replaced fish meal protein at levels 0, 25, and 50% by using non-conventional protein sources
(poultry by-product meal) in the first experiment. In the second experiment. Potato by-product and macaroni by-product were used at levels of 0, 25 and 50% to replace yellow corn in Nile tilapia diets, In each feeding trial a total number of 1200 Nile tilapia fish (30 gm body weight), randomly distributed in four groups per treatment (3 replicates in each), there were fed diets at 3% of total biomass of body weight (4 times) 6 days per week, The diets contained 30% CP and 4300 kcal/kg. the feeding. trials were extended for 140.
The results indicated that using 50% of poultry by-product meal to replace fish meal protein in the first experiment and 50% of potato by-product to replace yellow corn energy in the second experiment had the best values obtained for body weight gain feed conversion ratio, utilization of nutritients and digestibility of nutrients. The lowest cost of one kg body weight of fish was also obtained. The experimental diets were not affected on fish flesh palatability or total counts of bacteria.
Key words: Nile tilapia, poultry by-product, potato by-prodcut, digestibility coefficients.
