摘要

The present study investigated dietary Enteromorpha prolifera polysaccharide (EPP) on the growth performance, body composition and non-specific immunity of crucian carp Carassius auratus. Crucian carps with body weight of 51.24 +/- 4.08 g were randomly divided into five groups: one group was fed with basic diet, while the other four groups were fed with diets containing 20, 40, 60 and 80 g/kg EPP. After 60 days of feeding, dietary administration of 40 g/kg EPP increased the body weight gain rate, feed conversion ratio, specific growth rate, body crude protein content, intestine digestive enzyme activities, serum lysozyme activity, acid phosphatase activity, alkaline phosphatase activity, complement 3 level, superoxide dismutase activity and catalase activity and decreased body fat content and serum total cholesterol, triacylglycerol, alanine aminotransferase activity and glutamic oxaloacetic transaminase activity compared with those of the control group. All levels of EPP improved the resistance to Aeromonas hydrophilia compared with the control group. The results indicated that EPP could promote the growth of crucian carp and improve their disease resistance and may be used as a dietary supplement for crucian carp.
