摘要： 【目的】研究日粮中添加不同水平油橄榄叶对育肥期獭兔生长、血液生化指标及抗氧化能力的影响，为獭兔生产中合理添加油橄榄叶提供理论依据。【方法】将2月龄体重相似的128只生长獭兔随机分成4组，每组8个重复，在基础日粮中添加不同水平的油橄榄鲜叶（A0=0%、A1=5%、A2=10%和A3=15%），预试期7 d，正试期38 d。【结果】①饲喂不同比例的油橄榄叶对獭兔的采食无显著影响；②添加10%和15%油橄榄叶獭兔平均日增重显著高于对照组和5%水平组（P＜0.05），平均日增重提高7.60%；③添加油橄榄叶对葡萄糖、总蛋白、白蛋白、球蛋白和血红蛋白含量及红细胞数、中性粒细胞数等无显著影响，而对尿素氮、肌酐、白细胞数和淋巴细胞数影响显著（P＜0.05），但在正常生理值范围内；④添加10%—15%油橄榄叶对血液的抗氧化酶活性的影响显著（P<0.05）。【结论】在饲粮中适宜添加油橄榄叶不影响育肥獭兔的生产性能，不会对血液生化指标产生负面影响，添加10%—15%的油橄榄叶能增强獭兔血液的抗氧化力。

Abstract: 【Objective】 The purpose of this study was to investigate the effect of different dietary olive leaf levels on the growth performance, plasma biochemistry parameters and oxidation resistance of Rex rabbits during fattening period. 【Method】 One hundred and twenty-eight 2-month-old Rex rabbits with not significantly different initial live weights were randomly assigned into 4 groups with 8 replicates per group and fed basal diet supplemented with A0 (control group), A1, A2 and A3, respectively. The trial lasted for 7 d for adaptation, and 38 d for test. 【Result】The results showed that different dietary olive leaf levels affected the growth performance of Rex rabbit, especially adding olive leaf at 15% could significantly affect (P＜0.05) the average daily gain of Rex rabbits with 7.60% raising. Dietary olive leaf levels didn’t affect the daily feed intake, and some plasma biochemistry parameters such as glucose, TP, ALB, globulins, hemoglobin content, RBC and NC, but significantly affected BUN, crea, WBC and LC (P＜0.05). Different dietary olive leaf levels affected the antioxidant enzymes activity plasma of Rex rabbits, especially the adding amount was from 10% to15% (P＜0.05).【Conclusion】Considering the result of the growth performance, plasma biochemistry parameters and antioxidant defenses, olive leaf levels at 10%-15% could enhance the antioxidant force and didn’t affect the performance of the rabbit fattening and normal blood biochemical physiological parameters.
