Biochemical and Immune Indexes of Dairy Cows with Persistent Diarrhea, columnId=null, journalTitle=China Dairy, columnName=null, runingTitle=null, highlight=null, articleAbstract=[Objective] To study the effects of dandelion extract on blood biochemical and immune indexes of dairy cows with persistent diarrhea.[Method] A total of 120 dairy cows with persistent diarrhea with similar weight,parity and average milk yield were selected as the study objects in a large-scale farm in Linshu County,and they were divided into 4 groups（n=30） by using random number table method,which were control group,experimental group 1,experimental group 2 and experimental group 3,respectively.Each experimental group was supplemented with 0.4%,0.6% and 0.8% dandelion extract under the basic diet,respectively.6 replicates were set in each group,with 5 dairy cows in each replicate.The pre-test period was 7 days,and the formal test period was 35 days.[Result] The BUN,TG and TC indexes of experimental groups were significantly lower than those of control group（P<0.05）,and the BUN,TG and TC indexes of test group 2 were the lowest（P<0.05）,but there was no significant difference between the other two groups（P>0.05）.The ALB index of experimental groups was significantly higher than that of control group（P<0.05）,and the ALB index of experimental group 2 was the highest（P<0.05）,but there was no significant difference between the other two groups（P>0.05）.The IgA and IL-2 indexes in experimental groups were significantly increased compared with control group（P<0.05）,and the IgA and IL-2 indexes in experimental group 2 were the highest（P<0.05）.The IL-4 index of experimental groups was higher than that of control group（P<0.05）,and there was no significant difference among the three experimental groups（P>0.05）.[Conclusion] Adding dandelion extract to the basic diet can improve the blood biochemical indexes and enhance the mune capacity of dairy cows with persistent diarrhea.Considering the experimental results，adding 0.6% dandelion extract to thebasic diet was the best., authors=HU Wenfang, authorsList=HU Wenfang, authorCompany=Zhengshan Animal Husbandry Medical

articleAbstract=[目的]研究在持续性腹泻奶牛日粮中添加蒲公英提取物对其血液生化及免疫指标的影响。[方法]在临沭县某规模化养殖场选择120 头体重、胎次和平均产奶量相近的持续性腹泻奶牛为研究对象,采用随机数字表法将其分4 组（n=30）：对照组、试验1组、试验2组、试验3组。对照组饲喂基础日粮,各试验组在基础日粮中分别添加0.4%、0.6%和0.8%的蒲公英提取物,每组设置6 个重复,每个重复5 头,预试验期7 d,正式试验期35 d,统计试验结束后各组持续性腹泻奶牛血液生化及免疫指标。[结果]各试验组的BUN、TG和TC指标显著低于对照组（P<0.05）,试验2组的BUN、TG和TC指标最低（P<0.05）,其他两组无显著差异（P>0.05）。各试验组的ALB指标较对照组明显提高（P<0.05）,试验2组的ALB指标为最高（P<0.05）,其他两组无显著差异（P>0.05）。各试验组的IgA和IL-2指标较对照组显著提升（P<0.05）,试验2组IgA和IL-2为最高（P<0.05）。各试验组IL-4指标高于对照组（P<0.05）,且3 个试验组间的IL-4指标无显著差异（P>0.05）。[结论]持续性腹泻奶牛基础日粮添加蒲公英提取物可改善血液生化指标,提高机体免疫能力。综合考虑试验结果,日粮添加0.6%蒲公英提取物为最佳。, authors=胡文芳, authorsList=胡文芳, authorCompany=山东省临沭县郑山畜牧兽医站,山东临沭 276700, correspAuthors=null,
