Productive performance of tilapia (Oreochromis niloticus) fingerlings fed on diets containing fish meal stored under different storage methods and supplemented with BHT antioxidant [electronic resource].

Includes references.

Fish meal was stored for 26 weeks under three different storage methods (in store. under shade and in sun) with or without supplemented antioxidant (Butylated Hydroxy Toluene BHT). Two levels of BHT were used (125 and 250 ppm). Nine formulated diets were fed for 12 weeks to 460 tilapia fingerlings (0. neloticus. L) of about2.8g/ fish. All treated diets contained about 37% crude protein and 4800 kcal GE/Kg diet. The results of storing experiment showed that the best storage method is in store, and no need to add BHT,because the origin added ethoxyquin protected fish meal against oxidation and any changes in its chemical composition. In the feeding experiment, stored fish meal in store and without adding BHT offered the best results of growth parameters, feed efficiency and chemical composition of whole fish body.
