AbstractThe aim was to evaluate the addition of different levels the residue of the alcoholic extract of red
propolis as an additive in diets for Nile tilapia fingerlings. We used 80 fingerlings of tilapia (Oreochromis
niloticus) masculinized with initial weight of 0.11 ± 0.03 g, distributed in 20 aquariums of 15L of water in
a completely randomized design with four treatments and five replications in a recirculation system
water with constant aeration. The diets were prepared with commercial ration mashed with the
addition of (0, 0.50, 1.00 and 1.50%) of residue. The variables studied were: ultimate weight (UW),
Weight gain (WG), Whole-length (WL), Standard length (SL), Length of head (LH), Index profile (IP),
Index head (IH), Condition factor (CF), Width and Height. There was no positive effect (P<0.05) of
the use of red propolis residue on the productive performance of animals.
