Abstract :In this study, the effect of a dietary supplementation of Apium graveolens on growth performance, digestive enzyme activities and immune response of juvenile common carp insert ignore into journalissuearticles values( Cyprinus carpio ); were evaluated. C. carpio , with an average weight at the beginning of the experiment of 6.5 ± 0.07 g, were supplemented with a celery insert ignore into journalissuearticles values( Apium graveolens ); aqueous methanolic extract at a dose of 0% insert ignore into journalissuearticles values(control);, 0.1%, 0.5% or 1% over 45 days. Every 15 days, respiratory burst, lysozyme and myeloperoxidase activity were measured, and at the end of the study, haematological responses, growth performance and digestive enzyme activity were investigated. Respiratory burst and myeloperoxidase activity was significantly improved in all treated groups compared with the control group insert ignore into journalissuearticles values( P ˂ 0.05);. Lysozyme activity was highest in the 0.1% and 1% extract groups. At the end of the study, the final weight insert ignore into journalissuearticles values(FW);, weight gain insert ignore into journalissuearticles values(WG); and specific growth rate insert ignore into journalissuearticles values(SGR); were significantly increased in the 0.1% group compared with the other groups. The feed concentration ratio was decreased in the 0.1% and 1% groups compared with the control insert ignore into journalissuearticles values( P < 0.05 );. Haematological parameters were affected by A. graveolens extract intake insert ignore into journalissuearticles values(P ˂ 0.05);. The total white and red blood counts, haemoglobin content and haematocrit value were highest in the 0.1% extract group insert ignore into journalissuearticles values( P ˂ 0.05);. However, the mean cell volume and mean cell haemoglobin concentration were decreased in the 0.5% group insert ignore into journalissuearticles values( P ˂ 0.05);. Digestive enzyme activity insert ignore into journalissuearticles values(trypsin, amylase and lipase); in all experimental groups was significantly elevated compared with the control insert ignore into journalissuearticles values( P ˂ 0.05);. These results indicated an immunostimulatory and growth-promoting effect and increasing digestive enzyme activity of C. carpio supplemented with an A. graveolens aqueous methanolic extract.
