猪疥螨感染情况的诊断与治疗试验

Diagnosising and Treating Test About the Infection Situation of Swine Sarcoptic

采用涂片法、皮屑检查法和漂浮法,对新乡某猪场的保育猪、育肥猪和母猪疥螨感染情况进行了调查,结果其感染率分别为52.5%,70.2%和38.0%,平均感染率为53.57%.分别用伊维菌素、阿维菌素、敌百虫、双甲脒乳油、氰戊菊脂及螨净进行对比治疗。用药20天后,通过病灶变化记分、活螨计数、增重情况和安全性观察等指标综合判定,结果表明:螨净喷雾效果最差,治愈率仅为42.67%;其次为敌百虫涂擦,治愈率为68.25%;双甲脒喷雾治愈率70.45%;氰戊菊脂喷雾治愈率为83.36%;伊维菌素和阿维菌素这两种药物的不同用法对猪疥螨病均具有良好疗效,是最好的杀螨药物。经统计学分析,伊维菌素和阿维菌素组之间差异不显著(P>0.05),而它们的药效明显优于敌百虫、双甲脒乳油、氰戊菊脂、螨净,其差异极显著(P<0.01)。

Directly using the Smearing method,scraping experimental method and flotation method,this paper investigated the Conservation pig,Finishing Pigs and Sows with inflection of swine Sarcoptic mange in a swine farm in Xinxiang. The survey result showed that the inflection rate of 52.5% ,70.2% , 38.0% ,and the average inflection rate is 53.57%. Then these pigs were treated respectively by the method of Ivermectin, Abameetin, Dipterex, Amitraz EC, Fenvalerate and Mite Net. 20 days later, by the methods of lesions points,living sarcoptics counts, increasing weight situation and safety observation,the following were shown ： Mite Net spray effect was the worst,the cure rate was only 42.67% ;Secondly, Dipterex ex- posure cure rate was 68.25% ; Amitraz spray＇ cure rate was 70.45% ; Fenvalerate spray cure rate was 83.36% ; Both different usages of Ivermectin and Abamectin have the good efficacy to swine sareoptic mange. They were the best acaricidic drugs. Through statistical analysis,different groups of Ivermectin and Ahamectin were not significant （P〉0.05 ） , but their efficiencv were superior to trichlorfon ,Amitraz EC, Fenvalerate, Mite Net. Their difference were significant （P 〈 0.01 ）.
