摘要
[目的]为探究复方中草药对奶牛产后瘫痪症的临床疗效。[方法]本试验选用40头体况胎次相近的产后瘫痪患病奶牛,随机分为4组,复方中草药低剂量组、复方中草药中剂量组和复方中草药高剂量组,分别在基础日粮中添加200 g/头、400 g/头和800 g/头的复方中草药;西药治疗组奶牛注射硝酸士的宁注射液10 mL/头;另外选择10头健康奶牛作为对照组。[结果]复方中草药低、中、高剂量组对于奶牛产后瘫痪症的有效率分别为40%、60%和90%,治愈率分别为30%、50%和70%,而西药治疗组有效率为50%,治愈率为30%,说明复方中草药低剂量组治疗奶牛产后瘫痪症的效果与西药治疗组效果相当,而复方中草药中和高剂量的治疗效果更佳。与对照组相比,复方中草药低剂量组和西药治疗组奶牛的产奶量和4%标准乳产量显著降低(P<0.05),复方中草药中剂量组和复方中草药高剂量组不存在显著差异(P>0.05);西药治疗组牛乳中乳脂率和乳蛋白率显著降低(P<0.05),复方中草药低剂量组和西药治疗组牛乳的乳糖率显著降低(P<0.05),体细胞个数显著升高(P<0.05),复方中草药中、高剂量组与对照组无显著差异(P>0.05)。与对照组相比,复方中草药低剂量组和西药治疗组奶牛血清中的白蛋白、总蛋白和尿素氮显著降低(P<0.05),复方中草药中剂量组和复方中草药高剂量组与对照组无显著差异(P>0.05)。[结论]复方中草药对奶牛产后瘫痪症具有良好的治疗效果,疗效与给药剂量呈正相关,且复方中草药对奶牛产后瘫痪症的疗效优于传统西药治疗方法。
[Objective]The healthy growth of weaned calves is the premise to ensure the healthy lactation ability of dairy cows.The compound microecological agents have good application value in animal breeding,so it is of great significance to explore the effects of compound microecological agents on growth performance,diarrhea and serum related biochemical indexes of weaned calves for the healthy development of dairy farming.[Method]32 weaned Holstein calves with the same body weight at about 50 days of age were randomly divided into trial group A(control group),trial group B,C and D with 8 weaned calves in each group.The control group was fed with basic diet,while the trial group B,C and D were fed with 1 g,3 g and 6 g compound microecological agents respectively on the premise of basic diet,with a pre-feeding period of 7 days and a normal formal feeding period of 21 days.[Result]Compared with the control group,the body weight of weaned calves fed with compound microecological agents was effectively improved,and the digestibility of dry matter,crude protein and crude fat was increased significantly(P<0.05).The diarrhea rate of weaned calves fed with compound microecological agents was effectively reduced.In biochemical serum indexes,T-AOC,GSH-Px and SOD indexes were increased,while MDA content was decreased in weaned calves fed with compound microecological agents.The expression of IgA,IgM and IgG related to immune ability was detected,and it was found that the expression was increased in weand calves fed compound microecological agents,and there was a significant difference compared with the control group(P<0.05).[Conclusion]The compound microecological agents could effectively improve the growth performance of weaned calves,reduce the diarrhea rate,and improve the antioxidant capacity and immune capacity of the body.
