【摘要】：为了探讨小尾寒羊消化道线虫发病规律和药物防治效果,筛选驱虫效果最佳药物,试验随机选取小尾寒羊600只,分为芬苯达唑粉组、伊维菌素注射液组、阿苯达唑伊维菌素预混剂组、多拉菌素注射液组和生理盐水对照组,每组各120只。每组在试验前7天进行粪便虫卵检查,用药开始后,在每次用药的第7天分别进行粪便虫卵检查1次,在整个试验期间共检查4次。粪便虫卵检查采用饱和盐水漂浮法,计算粪便虫卵数、每克被检粪样中虫卵数量(EPG),比较每个试验组每个检查阶段的虫卵转阴率。结果表明:各组试验羊在用药7 d后虫卵转阴率由高到低依次为阿苯达唑伊维菌素预混剂组、伊维菌素注射液组、芬苯达唑粉组、多拉菌素注射液组,分别为92.5%、90.8%、90.0%和89.1%,阿苯达唑伊维菌素预混剂防治效果确实可靠,药效持续时间长,优于其他试验组。说明临床用药在防治小尾寒羊消化道线虫方面,阿苯达唑伊维菌素预混剂防治该病效果优于其他试验药物,值得推广应用。
[Abstract]:In order to investigate the incidence rule and control effect of nematode in digestive tract of small tail Han sheep and to screen the best drug for insect repellent, 600 small tail Han sheep were randomly selected and divided into two groups: fenbendazole powder group and ivermectin injection group. Albendazole ivermectin premixed group, Dora injection group and saline control group, 120 rats in each group. The fecal eggs of each group were examined 7 days before the trial. After the drug was used, the fecal eggs were examined once on the 7th day of each drug, and 4 times during the whole test period. Fecal eggs were examined by saturated saline floating method. The number of fecal eggs per gram of fecal samples was measured and EPGN was used to compare the negative rate of eggs in each stage of each test group. 92.5% 90.8% and 89.1%, respectively. The control effect of albendazole ivermectin premixed agent was reliable and lasting longer than that of other experimental groups. The results showed that albendazole ivermectin premixed agent was superior to other experimental drugs in the prevention and treatment of small tail Han sheep digestive tract nematodes, which was worth popularizing.
