摘　　要：试验旨在研究饲粮中添加加味枳术散对断奶仔兔生长性能、血常规、血清生化指标及肠道消化酶的影响。试验选取90只35日龄、体重相近、健康的新西兰白兔,随机分为5组,每组6个重复,每个重复3只兔。对照组仔兔饲喂基础饲粮,试验组分别在基础饲粮中添加2‰的恩诺沙星粉剂以及1‰、3‰和5‰的加味枳术散粉剂。预试期7 d,正式试验期14 d。结果显示,与对照组相比,加味枳术散组断奶仔兔的平均日增重显著升高(P<0.05),腹泻率明显降低且未出现仔兔死亡。与对照组相比,加味枳术散组断奶仔兔的免疫器官指数显著提高(P<0.05),且呈剂量依赖性。与对照组相比,加味枳术散组的白细胞、淋巴细胞和中性粒细胞数量均显著降低(P<0.05);5‰加味枳术散组的免疫球蛋白M含量显著升高(P<0.05)。加味枳术散可以增强小肠的脂肪酶、α-淀粉酶、纤维素酶和胰蛋白酶的分泌,并通过上调小肠中葡萄糖转运载体的基因表达水平,促进仔兔肠道对能量的吸收。研究表明,断奶仔兔饲粮中添加加味枳术散能够改善断奶仔兔的生长性能,增强机体免疫功能,降低机体的炎症水平,提高肠道的消化吸收能力,饲粮中加味枳术散的适宜添加水平为3‰~5‰。The purpose of this experiment was to study the effects of adding Modified Zhizhu Powder to diet on the growth performance,blood routine examination,serum biochemical indexes,and intestinal digestive enzymes of weaned rabbits.Ninety 35-day-old healthy New Zealand white rabbits with similar weight were randomly divided into five groups with six replicates in each group and three rabbits in each replicate.The rabbits in the control group were fed with basal diet,while the experimental group was fed with 2‰enrofloxacin powder and 1‰,3‰,and 5‰Modified Zhizhu Powder,respectively.The pre-test period was seven days,and the formal test period was 14 days.The results showed that compared with the control group,the average daily gain of weaned rabbits in the Modified Zhizhu Powder group increased significantly(P<0.05),the diarrhea rate decreased significantly,and there was no death of rabbits.Compared with the control group,the immune organ index of weaned rabbits in the Modified Zhizhu Powder group increased significantly(P<0.05),and it was dose-dependent.Compared with the control group,the number of white blood cells,lymphocytes,and neutrophils in the Modified Zhizhu Powder group decreased significantly(P<0.05).The content of immunoglobulin in 5‰Modified Zhizhu Powder group increased significantly(P<0.05).Modified Zhizhu Powder can enhance the secretion of lipase,α-amylase,cellulase,and trypsin in small intestine,and promote the absorption of energy in intestinal tract of young rabbits by up-regulating the gene expression level of glucose transporter in small intestine.The study indicates that the addition of Modified Zhizhu Powder in the diet of weaned rabbits can improve the growth performance,enhance the immune function,reduce the inflammatory level of the body,and improve the digestion and absorption capacity of intestinal tract.The suitable addition level of Modified Zhizhu Powder in diet is 3‰~5‰.
