摘　　要：选用40日龄永安麻鸡,设基础日粮组(对照组)、基础日粮+1000 mg·kg^(-1)芪欢散提取物组和基础日粮+2000 mg·kg^(-1)芪欢散提取物组,了解芪欢散提取物对永安麻鸡生产性能和血液生化指标的影响。结果表明,各试验组间麻鸡平均日采食量(ADFI)、平均日增重(ADG)以及饲料转化率(F/G)差异不显著,但添加芪欢散提取物可提高麻鸡ADG和ADFI,降低麻鸡F/G,2000 mg·kg^(-1)芪欢散提取物组生产性能好于1000mg·kg^(-1)芪欢散提取物组。1000 mg·kg^(-1)芪欢散提取物组腹脂率显著低于对照组(P<0.05),但各试验间屠宰率、半净膛率和全净膛率差异不显著(P>0.05)。芪欢散提取物可提高谷草转氨酶、谷丙转氨酶、碱性磷酸酶活性和总蛋白含量,降低尿素氮含量,并显著提高白蛋白含量。The experiment was conducted to investigate the effects of Qihuan herbal extraction （QHE） on the growth, meat yield and biochemical indices in Yongan chicken. For the study, 40-day-old Yongan chickens were randomly divided into 3 groups. The chickens were fed with （a） a basic diet as control, （h） the basic diet＋1000 mg·kg^-1 QHE or （c） the basic diet＋2000 mg·kg^-1 QHE. After 35 days, the chickens were slaughtered and data collected for analysis. The results indicated that the QHE produced no significant difference on average daily gain （ADG）, average daily feed index （ADFI） and feed/weight gain （F/G） on the chickens. On the other hand, the QHE additions increased ADG and ADFI, but lowered F/G, particularly when 2000 mg·kg^-1 QHE were incorporated in the feed. Comparing to the control group, the chickens fed with 1000 mg·kg^-1 QHE had significantly reduced percentage of abdominal fat （P〈0.05）. There was no significant difference among three groups on meat yield or percentages of semi-eviscerated and eviscerated weight. The activities of serum glutamic propylic transaminase, glutamic oxalacetic transaminase and alkaline phosphatase were increased by the additions of QHE. The plant extract improved total protein, decreased urea nitrogen, and significantly increased albumin content. It is, thus, con cluded that QHE might have a potential as a feed additive for the poultry industry.
