摘　　要：为了研究甘草霜对肉仔鸡生长性能、脏器指数及抗氧化能力的影响，选取90只1日龄的AA＋健康肉仔鸡，肉鸡前7d为预试期，肉鸡自由饮水、采食，从第8d开始，随机分为3组，每组3个重复，每个重复10只鸡，3组分别饮用浓度为0、50mg／1和100mg／l甘草霜的水溶液，饲养32d。研究结果表明：添加甘草霜对8～39日龄肉仔鸡的生长性能无显著影响（P〉0．05）；添加50mg／l甘草霜组的肉鸡肝脏指数显著高于0、100mgO组fP〈0．05）；试验组的肺脏和肾脏指数都高于对照组，但差异不明显（P〉0．05），试验组与对照组的脾脏指数差异不明显；适量添加甘草霜可明显提高肉仔鸡血清中抗氧化能力，50m鲫组的抗氧化能力显著高于0mg／1和100mg／l组（P〈0．05）。This study was designed to investigate the effects of licorice spray on growth performance and antioxidant capacity in Arbor Acres Plus （AA＋） broilers. The experiment selected 90 1-day-old AA＋ broilers. 7 days after the pre-breeding, the AA＋ broilers were randomly divided into three groups, with 3 replications per group and 10 broilers per replication. And they were given the same basic di- et, free access to water. The drinking water was added 0, 50, 100 mg/1 of licorice spray. Whole experiment lasted for 32 d. The results showed that the growth performance of 8-39-day-old broilers has no significant effect between groups（P〉0.05） when licorice spray was added. The broiler liver index in 50 mg/l group was significantly higher than 0 mg/l and 100 mg/l group（P〈0.05）; lung and kidney in- dex in the experimental group were higher than that of the control group, but had no significant difference （P〉0.05）. Serum antioxidant capacity in broiler of 50 mg/l group was significantly higher than 0 mg/l and 100 mg/l group（P〈0.05）. It was concluded that adding licorice spray in the drinking water may have a significant role in promoting some organs, and the addition can increase serum antioxidant enzyme activity, but had no significant effect on the growth performance of broiler chickens.
