摘要
球虫病是山羊常见的一种肠道寄生原虫病,可导致羊只下痢、消瘦、贫血、发育不良,甚至死亡.在宁夏中卫山羊选育场调查山羊球虫病的感染情况,测定不同季节和饲养模式下山羊粪便中的球虫卵囊数目,并对球虫种类进行形态学初步鉴定.结果表明:中卫山羊夏季感染球虫的程度最高,冬季和春季较低;春季和冬季球虫感染程度差异显著,春季和夏季、春季和冬季的感染程度差异均不显著,舍饲群和放牧群的感染程度差异不显著.形态学初步鉴定结果显示,中卫山羊感染的球虫种类主要有 8 种,分别为阿普艾美耳球虫(Eimeria apsheronica)、阿氏艾美耳球虫(E.arloingi)、艾丽艾美耳球虫(E.alijevi)、山羊艾美耳球虫(E.caprina)、羊艾美耳球虫(E.caprovina)、克氏艾美耳球虫(E.christenseni)、雅氏艾美耳球虫(E.ninakohlyakimovae)、家山羊艾美耳球虫(E.hirci).
Abstract
Coccidiosis is a common intestinal parasitic protozoan disease in goats,causing dysentery,wasting,anemia,stunted growth,and even death.To investigate the infection of coccidiosis in Zhongwei goats in Ningxia,the number of coccidiosis oocysts and the morphology of coccidiosis species in goat feces across different seasons were measured.The results showed that the intensity of coccidia infection in Zhongwei goats was highest in summer and lower in winter and spring.There was a significant difference in the infection intensity of coccidia between spring and winter,but no significant difference between spring and summer,or between spring and autumn.There was no significant difference in infection intensity between captive and grazing populations.The preliminary morphological identification results showed that there were eight species of Eimeria:E.apsheronica,E.arloingi,E.alijevi,E.caprina,E.caprovina,E.christenseni,E.ninakohlyakimovae,and E.hirci.In summary,this article investigates the infection status of Eimeria in Zhongwei goat breeding grounds in Ningxia across different seasons,and the results can lay a foundation for the prevention and control of Eimeria in Zhongwei goats.
