Effects of Macleaya cordata Extracts on Growth Performance and Immune Function of Squabs
摘要
Abstract
In order to investigate the effects of Macleaya cordata extract on growth performance,organ index,serum biochemical index and immune function of squabs,the trial had adopted one-factor completely random design.A total of 280 healthy ten-day-old squabs with similar weight were randomly divided into 7 groups with 10 replicates per group and 4 squabs per replicate.The control group (group A) was fed a basal diet,and the experimental groups (groups B to G) were fed diets added 30,40 and 50 mg/kg of Macleaya powder,40 mg/kg Macleaya cordata extract PE50,40 mg/kg Macleaya cordata extract BE60 and 150 mg/kg chlortetracycline,respectively.The experiment lasted for 15 days after pre trial period of 5 days.The results showed as follows:1) no significant differences were found in average daily weight gain and feed to gain among all groups (P＞0.05).2) No significant differences were found in thymus index and bursa index among all groups (P＞0.05).The spleen index of group E was significantly higher than that of control group (P＜0.01),and the spleen index of group D was significantly higher than that of control group (P＜0.05).The pancreas index of group D was significantly higher than that of control group,group B and group F (P＜0.05).3) Serum total protein content of group E was significantly higher than that of group G (P＜0.01).Serum low density lipoprotein content of group B was significantly higher than that of control group (P＜0.05).4) Serum immunoglobulin G content of group D was significantly higher than that of control group and group B (P＜0.01),and was higher than that of other groups (P＜0.05).Serum intedeukin 6 content of group E was significantly lower than that of control group (P＜0.05).The results indicate that Macleaya cordata extract can increase the immune organ index and the content of total protein,low density lipoprotein and immunoglobulin G in serum,thereby enhancing immunity of squabs.关键词
