高原牛羊胃肠道线虫驱治模式研究

根据高原地区＂春乏＂期间,牛、羊因胃肠道线虫病引起死亡严重的突出情况,自列项目,在全州范围划为三大区域,以项目区为中心,在牛、羊发病率和死亡率相对高的乡（镇）、村设点,将93330头（只）牛、羊分为三个组,作为高原地区牛、羊胃肠道线虫病防治技术模块,结果3个试验组用药前胃肠道寄生虫感染率均为100%,早晨在放牧前投喂赛爱吉夏结、克虫特和丙硫苯咪唑等药物后,7 d粪检EPG,虫卵转阴率和虫卵减少数均为100%。间隔7 d重复驱虫1次,防治效果显著。有计划的用驱虫药丙硫咪唑,克虫特、伊维菌素。在每年春季2~3月,秋季8~9月份进行两次驱虫。可提高牛、羊有机体的免疫力,降低牛、羊胃肠道线虫病的发病率和死亡率,减轻对养殖业的危害。

Study on Expelling Pattern of Plateau Cattle and Sheep Gastrointestinal Nema

According to the urgent conditions of serious death of cattle and sheep caused by gastrointestinal nema in spring lack period on plateau areas,a self-study project was conducted.Three large areas were separated in Gannan,the project was as center,several points were set in the counties and villages where cattle and sheep were sick and dead highly.93330 cattle and sheep were divided into 3 groups which were as technical module of prevention and control.The results indicated that for 3 groups infecting rates of different parasites were 100% before drugs using.Drugs Saiaijixiajie,Kechongte,Albendazole were fed before grazing in the morning,feces examination of EPG after 7 days,negative rate and decreasing amount of worm eggs were 100%.Expelling worms was conducted with 7 days interval,the effect of prevention and control was evidence.Drugs Albendazole,Kechongte and Ivermectin were used in planned way.Two times of expelling worms can improve organism immunity of cattle and sheep,and decline diseases and mortality infected with gastrointestinal nema in Spring（February and March） and in Autumn（August and September）,as well as decrease harm to livestock breeding.
