圈养肉食动物多种寄生虫混合感染调查及驱虫效果

本试验调查福州动物园10种24头(只)肉食动物寄生虫感染情况,运用麦克马斯特法获得寄生虫的种类,感染率和感染强度;利用驱虫前后感染强度对比获得驱虫效果。数据结果显示:(1)10种肉食动物中感染寄生虫6种,寄生虫总感染率为60%(6/10)。(2)6种动物共感染寄生虫14种,每种动物均混合感染。(3)感染强度以猞猁曼氏迭宫绦虫EPG为45710个/g最高,其次猞猁吸虫EPG为26740个/g,猞猁犬弓蛔虫EPG为450个/g。选取驱虫药进行驱虫效果观察结果显示:甲苯咪唑和丙硫苯咪唑线虫驱虫效果明显。     

动物园笼养鸽肠道线虫感染情况调查与分析

针对昆明某动物园鸽子病死及感染肠道线虫病情况进行调查,并采取药物治疗分析效果。对送检2只病死鸽检获虫体进行形态学鉴定,并采集园内40份鸽粪样(用药前的14份和用药后的26份)进行寄生虫的检测和鉴定。结果表明：2只病死鸽肠道解剖检获蛔虫161条;驱虫前线虫感染率为57.14%(8/14);采用阿苯达唑驱虫后的肠道线虫感染率为7.7%(2/26)。本次调查发现该动物园观赏鸽死于严重的肠道线虫感染,同时也发现高海拔地区鸽肠道线虫,尤其是蛔虫感染率高低同其所在地域的海拔高度可能存在相关性;从驱虫前后的结果发现,阿苯达唑对治疗肠道线虫感染有极显著效果;对其防治应采取定期肠道寄生虫检测,制定科学防控措施和方案。     

养殖场如何驱虫

1驱虫的方法1.1全群预防性驱虫。不要在寄生虫造成危害后才进行治疗性驱虫,要按程序进行全群驱虫,避免寄生虫的重复感染。1.2联合用药,综合防治。寄生虫的种类很多,药物的性能具有单一性,因此要采取联合用药,综合防治方法。1.3搞好环境卫生,减少感染机会,合理控制群体大小和饲养密度,增强体质,提高防病抗病能力。2驱虫时机的把握和驱虫次数2.1秋冬季(9～10月份)驱虫有利于畜群安全越冬。3～4月份驱虫有利于复膘。2.2转群前驱虫,防止寄生虫交叉感染。2.3分娩前驱虫,减少分娩应激导致寄生虫感染机会。注意用药计量准确,要根据畜种的体质强弱而…     

中甸牦牛肠道寄生虫感染调查及防治措施

为了解中甸牦牛消化道寄生虫感染情况,为牦牛寄生虫病提供有效的防治措施,从昆明小哨和香格里拉市随机采集106份新鲜粪便样品,采用饱和盐水漂浮法和自然沉淀法共检测出49份样品有寄生虫感染,平均感染率为46.23%。其中,线虫感染率为40.57%,吸虫感染率为16.98%,线虫和吸虫混合感染率为11.32%。调查表明,该地区中甸牦牛肠道寄生虫感染情况较为严重,以线虫感染为主。中甸牦牛对驱虫药比较敏感,驱虫效果明显,感染率显著低于自由放牧牛群。因此,生产中应加强采取防治措施,提高对寄生虫病的认识和防范,以确保牦牛养殖的健康可持续发展,提质增效。
