摘要
为筛选有效的抗鸽球虫药物,选用地克珠利(1 mg/kg)、磺胺喹恶啉钠(300 mg/kg)、磺胺氯吡嗪钠(300 mg/kg)、托曲珠利(25 mg/kg)、白头翁散(500 mg/kg)等5种抗鸡球虫药物进行了本试验,试验重复3次,每次分为用药感染组和不用药感染组,人工感染主要含有拉氏艾美耳球虫和鸽艾美耳球虫的混合孢子化卵囊,剂量为15×104个,以相对卵囊减少率作为抗球虫效果的指标。结果显示磺胺喹恶啉钠、磺胺氯吡嗪钠效果最好,相对卵囊减少率分别为99.9%和99.5%;其次是托曲珠利、白头翁散,相对卵囊减少率分别为96.7%和92.0%;地克珠利效果最差,相对卵囊减少率仅为75.6%。
To determine whether coccidiostats available for use in poultry were effective at controlling coccidiosis in pigeons,we tested 5 chemotherapeutic compounds including diclazuril （1 mg/kg）,sulfaquinoxaline sodium （300 mg/kg）, sulfachloropyrazine sodium （300 mg/kg）,tohrazuril （25 mg/kg） and pulsatilla chinensis powder （500 mg/kg）.The unmedicated controls and medicated birds were challenged with 15x104 oocysts of mixed-species field isolates containing primarily of Eimeria labbeana and E.columbae. The relative oocysts reduction rate （RORR） was measured to evaluate the efficacy of coccidiostats. The results showed that sulfaquinoxaline sodium and sulfaquinoxaline sodium have excellent efficacy against Eimeria infections in pigeons, which of the RORR was 99.9% and 99.5%, respectively. The toltrazuril and pulsatilla chinensis powder had intermediate efficacy, which of the RORR was 96.7% and 92.0%, respectively. And the diclazuril had partial efficacy, which of the RORR was 75.6%.
