油橄榄叶提取物对土鸡生产性能及血清生化指标的影响

摘要

To investigate effects of olive leaf extract (OLE) on production performance and serum bio‐chemical indexes in local chicken ,one hundred and sixty chicken were divided into control group (groupⅠ) ,0 .1 g/kg OLE group (groupⅡ) ,0 .3 g/kg OLE group (groupⅢ) and 0 .5 g/kg OLE group (groupⅣ) ,20 chicken per group .Experimental stage was five weeks .The average daily feed intake ,feed gain ratio and daily gain were analyzed .The contents of serum total protein (TP) ,albumin (ALB) ,globulin (GLB) and blood urea nitrogen (BUN) were measured .Meanwhile ,the activities of serum glutamic oxa‐loacetic transaminase (GOT) ,alanine transaminase (ALT) ,superoxide dismutase (SOD) and catalase (CAT) content were detected .Results :Compared with groupⅠ ,the daily gain ,levels of serum GLB and SOD were significantly increased ;average daily feed intake and feed gain ratio ,contents of serum BUN and MDA were significantly decreased with the increment of OLE .These results indicated that OLE sup‐plementation could improve production performance ,antioxidant capacity and immune function in local chicken .%为探讨油橄榄叶提取物（OLE）对陇南土鸡生产性能及血清生化指标的影响．将160只鸡随机分成对照组（Ⅰ组）、0．1g／kgOLE组（Ⅱ组）、0．3g／kgOLE组（Ⅲ组）和0．5g／kgOLE组（Ⅳ组），每组40只，实验期5周．统计鸡的平均日采食量、料重比和日增重情况，并检测血清总蛋白（TP）、白蛋白（ALB）、球蛋白（GLB）、尿素氮（BUN）含量及血清谷草转氨酶（GOT）、谷丙转氨酶（ALT）、超氧化物歧化酶（SOD）活性和丙二醛（MDA）的含量．结果显示，随着OLE添加水平的增加，与Ⅰ组相比，各实验组（Ⅱ、Ⅲ、Ⅳ）的日增重有不同程度的增加，平均日采食量、料重比均有不同程度的下降，血清GLB含量、SOD活性呈增高趋势，血清BUN和MDA含量呈下降趋势．提示日粮中添加OLE可以提高鸡的生产性能、抗氧化能力和免疫功能．
