Abstract :
Abstract[1] Effect of dietary prebiotics mixture (A-max) and mannan oligosaccharide (MOS), on growth performance, survival and body composition in Grass carp juvenile (Ctenopharyngodon idella) were investigated for 56 days. Practical diets were supplemented with 0, 0.5, 1.5, 2.5 and 3.5 g/kg A-max and MOS in a totally randomized design trial in triplicate groups. The experiment carried out in 36 fiberglass tanks with filled with 1400 lit water. 50 Grass carp juveniles with initial average weight 12.54 ± 0.42g were stocked and fed up to satisfy. The results showed that usage of dietary A-max lead to significant differences in body weight increase, percentage of body weight increase, length increase, specific growth rate, feed conversion ratio, feed intake and protein efficiency ratio between treatments and control (p g/kg A-max. On the other hand the treatments which fed A-max had no significant differences in survival rate with the control (P>0.05), even if the treatment which fed 1.5 g/kg prebiotic A-max showed significantly better position in body composition in comparison with the control and had significantly the most protein and less lipid amount (p g/kg dietary prebiotic A-max has benefit effects on juvenile grass carps. * Corresponding authors; shgh_science@yahoo.com
