Abstract :The feed efficiency and biochemical effects of vitamin A and E in diets for juvenile rainbow trout treated with to two different flow rates insert ignore into journalissuearticles values(0.9 and 2.1 l min-1, respectively); was investigated of some tissues. Four formulated diets insert ignore into journalissuearticles values(A18E0, A18E60, A0E30, A36E30); with different combination of vitamin A and E were tested, fish fed with these experimental diets during 12 weeks. Fish subject to 0.9 l min-1 flow rate was determined greater mortality, poorer FCR insert ignore into journalissuearticles values(feed conversion ratio); and poorer PER insert ignore into journalissuearticles values(Protein Efficiency Ratio); than fish subject to 2.1 l min-1 flow rate. There was no significant difference mortality of all diet groups subjects to 2.1 l min-1 flow rate insert ignore into journalissuearticles values(P > 0.05);. At 2.1 l min-1flow rate trials, muscle and kidney vitamin A concentration was highest in fish fed the diet with 18 mgvitA kg-1 and 36 mgvitA kg-1, and lowest in fish fed the diet with vitamin A-free insert ignore into journalissuearticles values(diet containing 0 mgvitA kg-1);. But at 0.9 l min-1flow rate trial, there was no significant difference in muscle and liver vitamin A concentration of all diet groups insert ignore into journalissuearticles values(P > 0.05);. Tissues malondialdehyde insert ignore into journalissuearticles values(MDA); level was highest in fish fed the Efree insert ignore into journalissuearticles values(diet containing 0 mgvitE kg-1); diet insert ignore into journalissuearticles values(p < 0.05);.
