摘　　要：试验选择30日龄的断奶仔兔80只,采用单因素试验设计,随机分为4处理组,每组20只。处理1为基础日粮(含30%羊草),其余3个处理分别为大蒜茎秆代替羊草5%、10%和15%,预试验期7 d,试验期为35 d,分别于试验开始第7、21和35天采集样品,分别分析日增重、料重比、免疫器官指数及血清中总蛋白、免疫球蛋白IgG和IgA含量的差异。结果表明,大蒜茎秆能够有效地提高肉兔的生产性能,添加大蒜茎秆组肉兔的日增重显著高于对照组,且料重比也显著低于对照组(P<0.05);随着大蒜茎秆添加量的增加,脾脏和胸腺指数及血清总蛋白、免疫球蛋白IgG和IgA的含量有增加的趋势,特别是21 d脾脏指数,35 d免疫球蛋白IgA含量较对照组有显著提高(P<0.05),可见大蒜茎秆有利于肉兔免疫功能的提高。A total of 80 1-month-old meat rabbits were randomly assigned to four groups and each group contained 20 rabbits. The dietary treatments were basal diet （contain 30% chinensis）, garlic straw instead of 5%, 10%, and 15% chinensis diet, respectively. The trial lasted for 7 days for adaptation and 35 days for sampling. At day 7, 21 and 35, the samples were collected, and daily gain, F/G, relative weight of immune organs, total protein and serum IgG and IgA was determined. The results showed that the performance was significantly affected by treatments. Average daily gain in 5%-15% garlic straw significant increased than that in the control, and FIG significant decreased than that in the control （P〈 0.05）. The treatment plus garlic straw had the tendency of increasing relative weight of immune organs, total protein and serum IgG and IgA. Especially, at day 21 the relative weight of spleen and at day 35 the serum IgA were significant higher than those in the control （P〈0.05）. Therefore, garlic straw also play a role in improving the immune function of growing rabbit.
