Coccidiosis remains one of the major problems in poultry all over the world. Very limited data on anticoccidial drugs in wild pigeons is available. The current study was aimed to understand the comparative efficacy of sulfadimidine, amprolium and triquen in wild pigeons of Dir district, Pakistan suffering from coccidiosis. The faecal matter of wild pigeons were purchased from the local market for coccidian infection. Results revealed that 88.8% (16/18) were found infected with Eimeria spp. Three positive groups were treated with sulfadimidine (0.2mg/L), amprolium (25mg/L) and triquen. Sulfadimidine was most effective (45%) followed by amprolium (44.6%) while triquen (24.0%) showed less effectiveness against coccidiosis in pigeons. Number of oocysts were 79, 81 and 80 before treatment and 60, 44 and 44 after treatment with sulfadimidine, amprolium and triquen respectively. This study showed that sulphadimidine, amprolium and triquen could not significantly reduce the coccidiosis in pigeons. Further studies are required to clear the mechanism of anti-coccidial drugs in wild pigeons.
球虫病仍然是全世界家禽面临的主要问题之一。关于野生鸽子抗球虫药物的数据非常有限。本研究旨在了解磺胺二甲嘧啶、安普罗姆和三嗪在巴基斯坦迪尔地区患有球虫病的野生鸽子中的比较疗效。从当地市场购买了受球虫感染的野生鸽子的粪便。结果显示，88.8%（16/18）的鸽子被发现感染了艾美尔球虫属。三个阳性组用磺胺二甲嘧啶（0.2mg/L）、安普罗姆（25mg/L）和三嗪进行治疗。磺胺二甲嘧啶效果最显著（45%），其次是安普罗姆（44.6%），而三嗪（24.0%）对鸽子的球虫病效果较差。磺胺二甲嘧啶、安普罗姆和三嗪治疗前的卵囊数分别为 79、81 和 80，治疗后的卵囊数分别为 60、44 和 44。本研究表明，磺胺二甲嘧啶、安普罗姆和三嗪不能显著减少鸽子的球虫病。需要进一步研究以阐明野生鸽子抗球虫药物的作用机制。
