【摘要】：为观察奶牛产前服用产复康中药散剂对产后预防子宫内膜炎的效果,试验分为预试验和扩大试验。预试验将66头临产奶牛随机分成试验1组、试验2组和对照组,各22头。从产前1d开始喂服产复康,添加量为试验1组每天200g/头、试验2组每天300g/头、对照组不添加。结果显示,试验1组和试验2组奶牛各项指标基本相似,且2个试验组较对照组胎衣不下和子宫内膜炎发病率明显降低。说明每天200g/头的剂量可以达到促进子宫复旧和预防子宫内膜炎的效果;在预试验的基础上,对不同地区的6个奶牛场352头奶牛进行了扩大试验,试验方法、观测指标和预试验类似,产复康的添加剂量为每天200g/头。结果显示,试验组与对照组相比胎衣不下和子宫内膜炎发病率分别下降9.92%和18.23%,产后85d妊娠率提高10.85%,产后第1次发情时间和第1次配种时间平均提前约10d。扩大试验的结果进一步证明服用产复康可降低子宫疾病发病率,促进奶牛子宫机能恢复,使奶牛提早发情配种,提高受胎率,对奶牛产后子宫内膜炎具有良好的预防作用。
[Abstract]:In order to observe the effect of traditional Chinese medicine powder on preventing postpartum endometritis, the experiment was divided into pre-test and expanded test. 66 parturient cows were randomly divided into trial group 1, group 2 and control group, 22 cows in each group. At the beginning of the first day before delivery, the dosage of 200g/ was added to group 1, 300g/ head per day in test group 2, and control group was not added. The results showed that the indexes of group 1 and group 2 were basically similar, and the incidence of endometritis in two groups was significantly lower than that in control group. The results showed that the dose of 200g/ head per day could promote the recovery of uterus and prevent endometritis. The observed index is similar to that of the pre-test, and the amount of additive used in the production of Fukang is 200g/ head per day. The results showed that compared with the control group, the incidence of placenta and endometritis decreased by 9.92% and 18.23 respectively, the pregnancy rate increased 10.85 days after delivery, the first estrus time and the first mating time were advanced by 10 days on average. The results of the extended experiment further proved that taking Yan-Fukang can reduce the incidence of uterine diseases, promote the recovery of uterine function, make the cows breed early, improve the conception rate, and have a good preventive effect on postpartum endometritis in dairy cows.
