  Four isonitrogenous and isocaloric diets (30.22 ± 0.02% CP and 19.007 ± 0.015 MJ kg-1 diet) were formulated to represent four dietary treatments. The first treatment (control) without poultry by-product (PM0), while the second, third and fourth diets formulated with substitution of fish meal by poultry by-product meal as 50, 75 and 100%, respectively. Each diet was fed to 100 juvenile tilapia (1.5 ± 0.05 g), in triplicate cement ponds of 2 m3. Fish were fed diets at a rate of 3% of its biomass daily divided into two equal portions. The highest (P<0.05) growth performance parameters (finial weight, weight gain, daily gain and specific growth rate) and best nutrient utilization (feed conversion ratio, protein efficiency ratio and net protein utilization) were recorded with PBM0 and PBM100% groups. The applied treatments showed in.. View More»
