A VALORIZATION OF BY-PRODUCTS THROUGH FEED FORMULATION FOR TILAPIA SP: ZOOTECHNICAL PERFORMANCE STUDY
In recent years valorization of biowaste attracts lot of attention worldwide owing to its high nutritional value and low price. In this work biowaste of animal (sardines) and plant (tomato) biowaste was used to formulate a new feed for red tilapia, that showed to be competitive in its price and zootechnical performance in comparison to commercially available tilapia feeds. Mathematical modelling was used to formulate optimal feed composition with favorable chemical composition and the lowest price. Formulated feed had high protein content (40.76%) and energy value of 279.6 Kcal/100 g. Optimised feed was manufactured and compared to commercially available reference feed in respect to feed intake, feed efficiency, specific growth rate of fingerlings of Tilapia sp and, most important, zootechnical parameters. With fish survival rate of 100% calculated feed conversion index for the formulated feed was 2.7.
