Farinha de algaroba em dietas para tilápia do Nilo (Oreochromis niloticus)

Abstract

It was evaluated the performance of Nile tilápia fed with diets containing mesquite hulls meal (MHM) in corn replacement. The diets were formulated to present the same level of protein (30% CP) and energy (3100 kcal/DE/kg ration) in which the ingredient-test replace part of the energetic ingredient (corn) in inclusion levels of 0, 50, 75 and 100%. It was used 60 fries of Nile tilapia with initial weight of 3,50± 0,05g, distributed in 20 polyethylene aquaria, which one with a total capacity of 70L in a recirculating system with constant aeration and inside biofilter. The variables studied were weight gain (WG), feed conversion (FC) and fillet income (FI). This byproduct was evaluated in a completely randomized blocks experiment with four treatments and five replications in a experimental period of 90 days. It was seen that the MHM can replace the corn in 75%, without affecting the animal performance in diets for Nile tilapia.
