抗球虫中药制剂对肉鸡肠道微生物的影响研究

Effect of Chinese Hebal Medicine against Coccidiosis on the Intestinal Microflora of Broilers

采用180只1日龄肉仔鸡随机分为5组,分别为对照组(第1组)、0.2%中宝杀球散组(第2组)、0.4%中宝杀球散组(第3组)、0.2%中草药+1mg/kg地克珠利组(第4组)、0.4%中草药+1mg/kg地克珠利组(第5组)研究抗球虫中药对肉鸡肠道微生物的影响。试验期为6周。结果表明,第3、4、5组肉鸡盲肠中大肠杆菌数量显著低于对照组(P<0.05),盲肠的乳酸杆菌和双歧杆菌及回肠、空肠的大肠杆菌、乳酸杆菌、双歧杆菌均差异不显著(P>0.05)。综合结果推荐添加0.4%中宝杀球散。

The experiment was conducted to study the effect of Chinese herbal medicine against coccidian on the intestinal micro flora of AA broilers. One hundred and eighty healthy AA broiler chickens of 1 day age were randomly divided into 5 treatments. Group 2 to 5 （the trail groups）were fed with 2% Chinese herbal medicine,0.4% Chinese herbal medicine,0.2% Chinese herbal medicine＋l mg/kg diclazuril,and 0.4% Chinese herbal medicine＋l mg/kg diclazuril, while the group 1 （the control group）was fed with the basal diet. The duration of the trial was 6 weeks. The results showed that the Escherichia coli of Group 3,Group 4 amd Group 5 was significantly lower than those of the control group （P〈0.05）. The lactobacillus and the bifidobacterium in the cecum,Escherichia coli,lactobacillus and bifidobacterium in the ileum and jejunum were not significant difference （P〉0.05） between the control group and the trial groups. So it was recommended that 0.4% Chinese herbal medicine was added into the diet.
