Residue of the process red propolis extract in commercial ration on performance of Nile tilapia fingerlings (Oreochromis niloticus) | Resíduo do processamento do extrato de própolis vermelha em ração comercial para alevinos de Tilápia do Nilo (Oreochromis niloticus)

English. The aim was to evaluate the addition of different levels the residue of the alcoholic extract of redpropolis as an additive in diets for Nile tilapia fingerlings. We used 80 fingerlings of tilapia (Oreochromisniloticus) masculinized with initial weight of 0.11 ± 0.03 g, distributed in 20 aquariums of 15L of water ina completely randomized design with four treatments and five replications in a recirculation systemwater with constant aeration. The diets were prepared with commercial ration mashed with theaddition 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) ofthe use of red propolis residue on the productive performance of animals.

Portuguese. Objetivou-se avaliar a adição de diferentes níveis do resíduo de própolis vermelha numa raçãocomercial sobre o desempenho de alevinos de tilápia do Nilo. Foram utilizados 80 alevinos de tilápiado Nilo (Oreochromis niloticus), masculinizados, com peso médio inicial de 0,11 ±0,03g, distribuídosem 20 aquários com 15L de água, num delineamento inteiramente casualizado, com quatrotratamentos e cinco repetições, em um sistema de recirculação de água com aeração constante.As dietas foram elaboradas com rações comerciais fareladas com a adição de (0; 0,50; 1,0 e 1,5%)de resíduo de própolis vermelha. Os alevinos foram alimentados quatro vezes ao dia, às 08:00; 11:30;13:30; 15:30h. As variáveis estudadas foram: Peso final (PF), Ganho de peso (GP), Comprimento total(CTOTAL), Comprimento padrão (CPADRÃO), Comprimento de cabeça (CCAB), Índice de perfil(IPERFIL), Índice de cabeça (ICAB), fator de condição (FC), largura e altura. Não houve efeitopositivo (P<0,05) do uso resíduo da própolis vermelha sobre o desempenho produtivo dos animais. Residue of the process red propolis extract in commercial ration on performance ofNile tilapia fingerlings (Oreochromis niloticus)AbstractThe aim was to evaluate the addition of different levels the residue of the alcoholic extract of redpropolis as an additive in diets for Nile tilapia fingerlings.
