为研究银杏叶复方对肉兔小肠黏膜形态及上皮内淋巴细胞和杯状细胞数量的影响,试验选择40只30日龄统一断奶的雌性健康新西兰兔,随机分为4组,每组5个重复,每个重复2只。基础日粮为玉米-豆粕-草粉型,其中对照组Ⅰ组饲喂基础日粮,试验Ⅱ、Ⅲ、IV组饲喂分别在基础日粮中添加0.50%、1.00%和1.50%的银杏叶复方,试验期30 d。结果表明,1.00%和1.50%银杏叶复方组的空肠绒毛高度和绒毛高度/隐窝深度(V/C)显著高于对照组(P<0.05),0.50%和1.00%组回肠V/C比值也显著高于对照组(P<0.05);1.00%和1.50%银杏叶复方组的空肠淋巴细胞数量显著高于对照组(P<0.05),0.50%银杏叶复方组的十二指肠杯状细胞数量显著高于对照组(P<0.05)。基于试验结果推断:饲粮中添加1.00%的银杏叶复方制剂,可维持和养护断奶肉兔的小肠黏膜组织。
In order to study the effects of Ginkgo biloba extract on intestinal mucosal morphology and the number of intraepithelial lymphocytes and goblet cells in rabbits, 40 healthy, newly weaned New Zealand white rabbits aged 30 days were randomly divided into 4 groups with 5 replicates , Each repeated two. The basal diet was corn-soybean meal-grass meal, in which the control group was fed the basal diet, and the groups Ⅱ, Ⅲ and IV were fed with 0.50%, 1.00% and 1.50% Ginkgo biloba respectively Compound, the test period 30 d. The results showed that villus height and villus height / crypt depth (V / C) of 1.00% and 1.50% Ginkgo biloba compound group were significantly higher than that of the control group (P <0.05). The ileal V / C ratio of 0.50% and 1.00% (P <0.05). The number of jejunal lymphocytes in 1.00% and 1.50% Ginkgo biloba extract group was significantly higher than that in control group (P <0.05), while in 0.50% Ginkgo biloba extract group, duodenal goblet cells The number of cells was significantly higher than that of the control group (P <0.05). Based on the results of the experiment, it is concluded that the gingko leaf compound prescription is added in the diet to maintain and maintain the intestinal mucosa of weanling rabbits.
