Abstract:
The present study evaluates the effect of dietary ginger (Zingiber officinale) on growth performance, haematological parameters, antioxidant status of common carp (Cyprinus carpio). Fish with initial weight of ۱۴±۱.۹۵ g were allocated into twelve tanks at density of ۱۸ fish per tank. Fish were fed four experimental diets containing ۰ (as control diet), ۰.۵, ۲ and ۵% ginger powder for ۵۶ days. After ۵۶ days of culture, fish fed with ۲ and ۵% ginger diets showed significant increase in final weight, weight gain, specific growth rate (SGR) and feed conversion ratio (FCR) (p<۰.۰۵) compared to the control diet. Significant higher number of leucocytes (WBC), erythrocytes (RBC), haematocrit, lymphocyte, monocyte and neutroplil neutrophil were found in the fish fed with ۲ and ۵% ginger diets compared to the control diet. Superoxide dismutase (SOD), catalase (CAT) and Glutathione peroxidase (GPX) enzyme activities and Malondialdehyde (MDA) levels were significantly higher in the groups fed ۲ and ۵% ginger diets (p<۰.۰۵). SOD, CAT and GPX mRNA expression levels of fish fed with ۲ and ۵% ginger diets were significantly down-regulated compared to the control diet (p<۰.۰۵). The results suggested that dietary ginger can improve the growth performance, health status and antioxidant capacity of common carp.
