| This study was conducted to evaluate performance and body composition of tilapia (Oreochromis niloticus) fed diets containing byproducts aerial parts of cassava meal (Manihot esculenta), mesquite pod meal (Prosopis juliflora), cocoa meal (Theobroma cacao) and palm kernel cake (Elaeis guineensis) and to analyze the economic viability of the feed. A total of 1,350 juvenile males (100 g) were distributed in 15 cages (1 m³) in completely randomized design with five treatments (basal diet and four test diets) and three replicates. The following aspects were evaluated: final weight, total feed intake, total weight gain, feed conversion, specific growth rate, protein efficiency ratio and survival rate, dry matter, crude protein, fat and ash body, the average cost... |

| The objective of the present study was to evaluate the apparent digestibility coefficients of dry matter (DM), crude protein (CP) and gross energy (GE) of the following agro-industrial byproducts: cassava leaf (Manihot esculenta), mesquite bean (Prosopis juliflora), cotton (Gossypium species), cocoa (Theobroma cacao), soursop (Annona squamata) and African oil palm cake (Elaeis guineensis) for Nile tilapia (Oreochromis niloticus). Fish from two weight classes (200±11 and 300±32 g) were stocked in tanks and fed a reference diet plus 30% of one tested byproduct with the addition of 0.1% chromic oxide. The fish were routinely moved to digestibility aquariums for feces collection, in a completely randomized design (n=3). The apparent digestibility coefficient... |
