  Effects of Partial Replacement of Fishmeal by Locally Available Ingredients on Growth Performance and Feed Utilization Efficiency of Nile Tilapia, Oreochromis niloticus
  Author(s): Teshome Belay Eshete, Kassaye Balkew Workagegn* and Natarajan Pavanasam
  
  The present study was aimed at evaluating the effects of partial replacement of fishmeal with locally available feed ingredients on growth performance, feed utilization efficiency body composition and apparent digestibility coefficient of protein (ADCp) of Nile tilapia. For this purpose, seven experimental diets were prepared using 0%, 10% and 20% Jatropha, Alfalfa and Brewery waste as partial replacement of fishmeal. Healthy mixed-sex Nile tilapia with an average body weight of 6.5 ± 0.56 g were collected from Ziway Fish and Other Aquatic Life Research Center and stocked in fiberglass plastic tanks in triplicates at a stocking density of 20 fish per tank. The fish were fed three times a day with a control diet for one week and then with experimental diets for a period of four months at a rate of 3-6% body weight of fish. For ADCp studies, fish were reared for 20 da.. View more»
