摘要:

为更好了解小蓟的药理作用，开发中兽药，采用单因素随机化设计方法，选择健康、体重相近、性别相同的13周龄公银黑狐80只，随机分为5个处理组，每组16只。其中A组为对照组，饲喂基础日粮；B、C、D、E为试验组，在基础日粮中分别添加0.2%、0.4%、0.8%、1.6%的小蓟。结果表明：小蓟的添加提高了平均日采食量、平均日增重增加，降低了料重比；鲜皮重、鲜皮长度有所增加，其中D组（0.8%）效果最好，与对照组相比差异显著（P<0.05）；增强了机体的免疫功能，使得肝脏和脾脏等器官发育良好；通过调节脂质代谢水平，血清中甘油三酯和总胆固醇的含量降低，白蛋白和球蛋白的比值呈上升趋势，D组（0.8%）效果最好，与对照组相比差异显著（P<0.05）。小蓟在银黑狐日粮中的添加比例为0.8%效果最好。

Abstract:

In order to better understand the pharmacological action of herba cirsii for development of veterinary drugs，single factor random design was adopted, health, 13 weeks of age, 80 male silver foxes with similar weight and same sex,were chosen and were randomly divided into for five treatment groups (n=16)，in this experiment,. Which group A as the control group, fed the basal diet; group B, C, D and E as the experimental group, the basal diet was supplemented with 0.2%, 0.4%, 0.8% and 1.6% of thistle. The results of the experiment showed that the thistle was added in the diets of silver fox, average daily feed intake and average daily gain increased, feed gain ratio decreased; fresh weight and fresh skin length increased, and the D group (0.8%) had the best effect, compared with the control group had significant difference (P<0.05); the body′s immune function enhanced, so that the liver and spleen and other organs development good; by regulating lipid metabolism, triglyceride and total cholesterol in serum content reduced,the ratio of albumin and globulin showed an upward trend, in which the D group (0.8%) had the best effect, and the difference was significant (P<0.05), compared with the control group. Conclusion:thistle was helpful for improving animal performance as feed additive of Chinese herbal medicine,, the most suitable proportion was 0.8% in the silver fox diet.
