عنوان انگلیسی The effects of different levels of biogen probiotic additives on growth indices and body composition of juvenile common carp (Cyprinus carpio L.)
چکیده انگلیسی مقاله An experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, Cyprinus carpio. Four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % Biogen probiotic were used to feed fish. Seventy-two juvenile common carp (65 ? 3.5g) were randomly distributed between 12 fiberglass tanks of 500 L capacity. During 60 days of feeding trial, the fish receiving probiotic feeds showed significantly higher growth performance in terms of weight gain (WG), specific growth rate (SGR), protein efficiency ratio (PER), food conversion ratio (FCR) and survival rate (SR) in comparison with those fed the control diet (P0.05) in fish fed diets containing 0.1 and 0.2 percent of probiotic. Fish carcass composition in the diets receiving probiotic improved from initial values i.e. higher levels of protein and lipid with lower levels of moisture and ash content and showed significant difference (P< 0.05) only with the basal control diet. There were no significant differences (P > 0.05) in body composition between the treatments which received probiotic. Feeding juvenile carp with diets containing Biogen probiotic improves growth performances and feeding efficiency in them; the optimum addition of probiotic is 0.3 g/100gof diet.
