Abstract :Nile tilapia, Oreochromis niloticus L., infected with Vibrio anguillarum or not infected were fed balanced diets containing vegetal insert ignore into journalissuearticles values(solvent extracted soy bean meal insert ignore into journalissuearticles values(SBM);); or animal insert ignore into journalissuearticles values(meat and bone meal insert ignore into journalissuearticles values(MBM);); protein sources in order to demonstrate the apparent nutrient and energy digestibility. Regardless of protein sources in the diets, feed intake was lower in the infected group. Apparent nutrient insert ignore into journalissuearticles values(ADDM and ADCP); and energy digestibility insert ignore into journalissuearticles values(ADkJ); values of Nile tilapia fed the SBM diet were significantly better insert ignore into journalissuearticles values(P < 0.05); than those fed the CONT and MBM diets and changed little between the measurement days in both groups insert ignore into journalissuearticles values(non-infected and infected);. Although no visible symptoms associated with vibriosis were evident on either the skin or internal organs, the significantly lower insert ignore into journalissuearticles values(P < 0.05); ADDM, ADCP, and ADkJ values obtained between day 1 and 10 insert ignore into journalissuearticles values(specifically on days 3 and 10); in the infected group fed the CONT and MBM diets might have implicated the pathogenicity of the bacteria. Further research concentrating on higher amounts of solvent extracted soy bean and meat and bone meal, different environmental conditions and doses of infection with V. anguillarum and immune response parameters including physiological and cellular stress responses is needed in order to identify the overall apparent nutrient digestibility of plant and animal protein sources in Nile tilapia infected with V. anguillarum.
