促反刍散治疗牛前胃弛缓的临床试验

The Clinical Trial of Bovine Forestomach Atony Treated by Rumination Stimulant

将364头患前胃弛缓的荷斯坦奶牛随机分为4组,分别用剂量为50、100、150 g/d·头的促反刍散和200 g/d．头的健胃散(对照)进行治疗,观测不同剂量促反刍散对牛前胃弛缓的治疗效果。结果表明,中剂量组(100 g/d·头)和高剂量组(150 g/d·头)之间治愈率差异不显著(P＞0．05),与低剂量组和对照组相比,治愈率分别提高了21．98％和20．88％(P＜0．01),表明促反刍散组方合理,疗效确实,可以在生产中应用。

Three hundred forty--six Holstein cows suffering from forestomach atony were randomly divided into 4 groups to observe the treatment effects of rumination stimulant on bovine forestomach atony, the daily treatment amount of rumination stimulant for three groups were 50 g/head, 100 g/head, and 150 g/head, respectively, the fourth group received digestion accelerant of 200 g/head as control group. The results showed that the similar recovery rates of high dosage （150 g/head） and medium dosage （100 g/head） were 21.98% and 20.88% greater than that of low dosage （50 g/head） and control group, respectively, which indicated that the properly prescribed rumination stimulant with proved curative effects could be extended in the dairy cattle production.
