| 【目的】 研究饲粮中添加达乌里胡枝子提取物（Extractive of Lespedeza davurica，LDE）对肉仔鸡生产性能及抗氧化能力的影响。【方法】 将350 只健康1 日龄商品代Avian肉仔鸡随机分为7 组，每组5个重复，对照组（CK）饲喂基础日粮，1～3 组饲喂基础日粮添加达乌里胡枝子乙酸乙酯萃取物 20，30，40 mg/kg；4～6 组饲喂基础日粮添加达乌里胡枝子正丁醇萃取物40，50，60 mg/kg。试验期42 d，42日龄时每组取5只鸡采血并取组织器官，测定血清及组织器官的超氧化物歧化酶（T-SOD）、谷胱甘肽还原酶(GR)活性及丙二醛（MDA）含量，并测定日增质量及料肉比。【结果】 达乌里胡枝子提取物对肉仔鸡的生长性能有改善作用，可以提高肉仔鸡的日增质量，降低料肉比；可增强肉仔鸡血清与心脏中T-SOD 活性，显著增强肝脏和肾脏的T-SOD活性(P＜0.05)；可增强肉仔鸡血清及肝脏、肾脏中GR活性，除试验1组外，均能显著增强心脏中GR活性(P＜0.05)；可显著降低肉仔鸡血清、心脏、肝脏和肾脏的MDA含量(P＜0.05)。【结论】 达乌里胡枝子提取物对肉仔鸡生产性能有促进作用，可提高肉仔鸡的抗氧化能力。 |

| Abstract: |
| 【Objective】 The effects of Lespedeza davurica extractive (LDE) on growth performance and antioxidant indices of broiler chickens were discussed.【Method】 A total of 350 1-day healthy Avian broilers of commercial strains were randomly assigned to seven treatments with five replicates.The experimental stage was forty-two days.The control group (CK) was fed basal diet,group 1 to 3 fed basal diet supplemented with 20,30,40 mg/kg of ethyl acetate extractive of LDE,group 4 to 6 fed basal diet supplemented with 40,50,60 mg/kg of n-butanol extractive of LDE.42-day-old broilers were slaughtered for blood,heart,liver and kidney.The antioxidant enzymes and Malondialdehyde (MDA) were measured in serum,heart,liver and kidney.The enzymes included superoxide dismutase(T-SOD),glutathione peroxidase (GR).Daily weight gain and feed conversion ratio were measured,too.【Result】 (1) Supplementing different levels of LDE can improve performance of broilers,elevate daily weight gain and improve feed conversion ratio;(2)Supplementing different levels of LDE can enhance T-SOD activity in serum and heart,significantly enhance T-SOD activity in liver and kidney(P＜0.05);(3)Supplementing different levels of LDE enhances GR activity in serum,liver and kidney,and significantly enhance GR activity in heart(P＜0.05) except for treatment 1；(4)Supplementing different levels of LDE significantly degrades MDA content in serum,heart,liver and kidney （P＜0.05). 【Conclusion】 The LDE has auxoaction in broilers’ performance,and it can elevate antioxidant function of broiler chickens. |
