Comparative experiments were carried out on the effectiveness of some antiparasitic agents for the treatment and prophylaxis of estrosis in sheep. An evaluation is made of all methods applied in the modern technologies of sheep raising. It was found that the method of fumigation of airtight premises using negouvon at the rate of 0.6 g/m3 and a 60-min exposure was adequate and effective for group treatment. Negouvon proved to be well tolerated by sheep and had no essential effect on the level of cholinesterase. The use of the preparation ranid is economically justified only with animals having a mixed infection of Fasciola hepatica and O. ovis larvae.
对一些抗寄生虫药物治疗和预防绵羊狂蝇蛆病的效果进行了对比试验。对现代养羊技术中应用的所有方法进行了评估。结果发现，使用剂量为0.6克/立方米的蝇毒磷对密闭场所进行熏蒸60分钟的方法，对于群体治疗是充分且有效的。结果表明，绵羊对蝇毒磷耐受性良好，且对胆碱酯酶水平没有实质性影响。仅在动物感染肝片吸虫和绵羊狂蝇幼虫混合感染时，使用ranid制剂在经济上才是合理的。
