[目的]为探究中药复方对奶牛胎衣不下治疗效果与受胎率的影响。[方法]本试验探究了天津市某奶牛场产后奶牛的胎衣不下患病情况,并采用不同处理方法进行治疗。[结果]通过观察临床症状和阴道检查等诊断方法,该场的245 头产后奶牛中,共有40 头被确诊为胎衣不下,其中初胎奶牛发病率为20.00%,二胎奶牛发病率为14.71%,三胎奶牛发病率为13.92%,四胎奶牛发病率为18.42%,总发病率为16.33%;通过不同的处理方法,对照组治愈率为33.33%,中药治疗组治愈率为85.71%,抗生素治疗组最高,为92.86%;对照组发情率最低,为33.33%,中药治疗组发情率最高,为92.86%,抗生素治疗组次之,为85.71%;对照组受胎率为25.00%,中药治疗组受胎率为85.71%,抗生素治疗组受胎率为71.43%。[结论]中药复方能够有效治疗奶牛产后胎衣不下,治疗效果与抗生素治疗相近,且能够有效提高胎衣不下患病奶牛的发情率和受胎率。

[Objective] In order to investigate the influence of Chinese medicine compound formula on the treatment effect and fertility rate of cows with retained placenta. [Method] This experiment investigated the prevalence of retained placenta in postpartum cows in a dairy farm in Tianjin,and used different treatments for the treatment. [Result] By observing clinical symptoms and vaginal examination,a total of 40 postpartum cows were diagnosed with retained placenta among 245 postpartum cows in the farm,of which the incidence rate of primiparous cows was 20.00%,that of second-parous cows was 14.71%,that of third-parous cows was 13.92%,that of fourth-parous cows was 18.42%,and the total incidence rate of cows was 16.33%;by means of different treatment methods,the cure rate was 33.33% in the control group,85.71% in the Chinese medicine compound treatment group,and 92.86% in the antibiotic treatment group; the oestrus rate was the lowest in the control group,33.33%,the highest in the Chinese medicine compound treatment group,92.86%,and the second highest in the antibiotic treatment group,85.71%; the fertility rate was 25.00% in the control group,85.71% in the Chinese medicine compound treatment group,and 71.43% in the antibiotic treatment group. [Conclusion] Chinese medicine compound can effectively treat postpartum retained placenta in dairy cows,and the therapeutic effect is similar to that of antibiotic treatment,and it can effectively improve the estrus rate and fertility rate of cows with retained placenta.
