The mallard duck (Anas platyrhynchos) is a host to internal and external parasites. A heavy parasite burden indicates poor immunological status and a pathogen-contaminated environment. The present study describes the macroscopic and microscopic examination of isolated intestines and gizzards of 130 mallard ducks from birds kept in the breeding farm. Scrapings of intestinal mucosa were examined by flotation and with the sedimentation method. The results of the flotation method indicate the presence of coccidia oocysts in the ileum scrapings from one of five male mallards aged six weeks, one out of five aged 10 weeks and three out of five aged 12 weeks. In female mallards, oocysts were found in two of five birds aged 12 weeks and in two of five aged 16 weeks. No macroscopic lesions were found in the intestinal mucosa. Adult forms of the nematode Amidostomum anseris were found in the gizzards of six mallards aged 20 weeks and in two aged 22 weeks. The relatively low prevalence of parasitic infections reflects the purity of the environment, good immunity status of the birds and good management of the farm.
绿头鸭（Anas platyrhynchos）是体内和体外寄生虫的宿主。寄生虫负担过重表明免疫状态不佳以及病原体污染的环境。本研究描述了对来自养殖场饲养的130只绿头鸭的离体肠道和砂囊进行的宏观和微观检查。通过浮选法和沉淀法对肠黏膜刮片进行检查。浮选法的结果表明，在5只6周龄雄性绿头鸭中的1只、5只10周龄中的1只以及5只12周龄中的3只的回肠刮片中存在球虫卵囊。在雌性绿头鸭中，在5只12周龄的鸭中有2只以及5只16周龄的鸭中有2只发现了卵囊。在肠黏膜中未发现宏观病变。在6只20周龄和2只22周龄的绿头鸭的砂囊中发现了线虫鹅裂口线虫的成虫。寄生虫感染的相对低患病率反映了环境的纯净、鸟类良好的免疫状态以及养殖场良好的管理。
