精品文档---下载后可任意编辑东北地区笼养鹤类肠道寄生虫病调查及分析中期报告摘要笼养鹤是东北地区重要的保护动物，但在养殖过程中很容易感染肠道寄生虫，对饲养管理形成难题。本讨论通过对养殖场笼养鹤的样本进行病原学检测、形态鉴定和统计学分析等多个方面的调查，分析了笼养鹤类肠道寄生虫病的流行状况、发病原因和危害，并提出了预防和治疗措施。讨论结果表明，东北地区笼养鹤类肠道寄生虫主要分布在不同生长阶段，并且存在多种混合感染情况，其中最常见的寄生虫是柿叶线虫、回回线虫和毛细线虫。感染肠道寄生虫会引发鹤类的拉稀、食欲不振、消瘦、生产性能下降等严重症状，严重时还会引起鹤类死亡。因此，笼养鹤类肠道寄生虫病的预防和治疗是十分重要的，并且要制定科学的养殖管理法律规范，加强笼养鹤类肠道寄生虫病的防治工作。关键词：笼养鹤；肠道寄生虫；柿叶线虫；回回线虫；毛细线虫。AbstractCaptive cranes are important protected animals in northeastern China, but they are susceptible to intestinal parasitic infections during farming, posing a challenge to feeding management. In this study, we conducted a comprehensive investigation into the epidemiology, etiology, morphology, and statistical analysis of captive crane intestinal parasitic diseases by studying samples from a farm. We have analyzed the prevalence, causes, and hazards of intestinal parasitic diseases in captive cranes and proposed prevention and treatment measures. The results show that intestinal parasites in captive cranes in northeastern China are mainly distributed in different growth stages and are characterized by mixed infection. The most common parasites are Nematodirus helvetianus, Heterakis gallinarum, and Capillaria spp. Infection with intestinal parasites can cause serious symptoms such as diarrhea, loss of appetite, weight loss, and decreased productivity in cranes, and may even cause their death. Therefore, prevention and treatment of captive crane intestinal parasitic diseases are crucial. It is also necessary to develop scientific farming management standards and strengthen the prevention and control of parasitic infections in captive cranes.Keywords: captive crane; intestinal parasites; Nematodirus helvetianus; Heterakis gallinarum; Capillaria spp.
