Resumo: |
The objective of this work was to evaluate the inclusion of mango wastes bran on apparent digestibility, productive performance, heterogeneous growth, body yield (with and without head), hepatosomatic index, somatic and visceral indexes, fat and organs weight in Nile tilapia. In the digestibility experiment were used 48 animals with average weight of 53.9 ± 1.04 g and for the performance experiment 300 juveniles were used with the average weight of 44.3 ± 2.7 g. The experimental design for both was randomized with four treatments and the performance experiment with five replicates, and digestibility with three replications. The treatments consisted of four isoproteic- and isoenergetic diets with different levels of inclusion of mango waste bran (0, 5, 10 and 15%). The digestibility coefficients were: dry matter (79,62; 76,94; 76,46 and 78,02%), crude protein (88,80; 87,40; 87,18 and 87,80% ), crude energy (77,78; 75,96; 76,42 and 77,48%), digestible energy (3304; 3320; 3395 and 3484 kcal/kg) and digestible protein (29,28; 30,35; 29,82 and 29,79%). There are no visible treatment effects on the variables analyzed (p> 0.05). We recommend the inclusion of about to 15% of mango wastes on Nile tilapia feeding without compromising the variables evaluated in this study |
