Abstract: The experiment was aimed to investigate the effects of chlorogenic acid on growth performance, non-specific immunity and antioxidant functions of Cyprinus carpio var. Jian. 360 Cyprinus carpio var. Jian with an average weight of(62.93±5.82) g were selected, and were randomly divided into 5 groups(group A~E). 0, 100, 200, 400 and 800 mg/kg of chlorogenic acid were added into the diets of 5 groups, respectively. On the 10^th, 20^th, 30^th, 40^th day of the experiment, each group were sampled to measure weight gain rate, head kidney index, spleen index, phagocytic index of leukocyte, vitality of lysozyme, the SOD, CAT, T-AOC and MDA in blood. Results showed that: The 40^th day, the weight gain rate of C group was significantly higher than that of A group(P<0.05);the head kidney index of C group was significantly higher than that of A group(P<0.05) at each time;the 10^th, 20^th and 30^th day, the spleen index of D group was significantly higher than that of A group(P<0.05);the 10^th, 20^th and 30^th day, the phagocytic rate of leukocyte of C group and D group was significantly higher than that of A group(P<0.05);each time the activity of plasma lysozyme of D group was significantly higher than that of A group(P<0.05);In addition, the SOD difference of group E and A was not apparent(P<0.05) on the 40^th day, while the SOD of other groups in each period were significantly higher than that of A group(P<0.05). The 30^th and 40^th day, the CAT of group D was significantly higher than that of A group(P<0.05);the 20^th, 30^th and 40^th day, the T-AOC of group D was significantly higher than that of A group(P<0.05);the 20^th, 30^th and 40^th day, the MDA of C group and D group was significantly lower than that of A group(P<0.05). Comprehensive changes of the indicators showed that: ① Adding 200 mg/kg chlorogenic acid can significantly promote the growth of Cyprinus carpio var. Jian;② Adding 200~400 mg/kg chlorogenic acid can significantly enhance the nonspecific immune and antioxidant of Cyprinus carpio var. Jian;③ It has a certain degree of inhibition to the growth of Cyprinus carpio var. Jian and non-specific immunity and antioxidant function to add a high dose of chlorogenic acid for a long period of time.
