摘要：腹泻疾病是生猪生长发育阶段易发生的一类传染性疾病，发病后患病猪排便频率显著增大，粪便不成形。临床上猪腹泻疾病的发病原因十分复杂，通常是由病毒细菌寄生虫感染引发。仔猪阶段尤其是哺乳仔猪和断奶仔猪是发病的第2个高峰期。疾病防控和疾病治疗中要明确具体的致病原因，然后制定针对性的防护方案，提高整体的防控效果，将疫病控制在萌芽阶段，降低发病率和死亡率，为养殖户带来更高的经济效益。该文主要论述猪腹泻病发病原因、临床症状和预防措施。

Abstract：Diarrhea disease is a kind of disease that is easy to occur during the growth and development of infectious disease pigs. The clinical causes of porcine diarrhea disease are very complex，usually caused by the infection of virus，bacteria and parasites. Piglets，especially suckling piglets and weanling piglets，are the second peak period of the disease. In Disease Prevention and Control and disease treatment，the specific causes of disease should be clearly identified，and then targeted prevention and control programs should be formulated to improve the overall prevention and control effect，control the disease in its embryonic stage，and reduce the morbidity and mortality，bring higher economic benefit to the farmer. This paper mainly discusses the causes，clinical

symptoms and preventive measures of porcine diarrhea.

Keywords：porcine diarrhea disease，etiology，prevention

0引言

腹瀉疾病是生猪养殖管理中的一种常发病和高发病，该类疾病传播速度较快，一旦在一窝仔猪中出现，个别患病病例会短时间内向整个群体快速传播蔓延。感染初期虽然造成的死亡率相对较低，但是对猪的生长发育构成威胁，普遍表现为生长发育周期延长，饲料利用率下降，身体逐渐消瘦。如果表现为多种病原混合感染，会使临床症状进一步加重，临床症状复杂，给疾病的诊断和防控工作带来巨大难题。需掌握猪腹泻疾病发生的实际原因，然后从预防措施入手，及时切断病原的传播途径，保证患病猪快速恢复健康，增强猪身体抵抗力，有效预防腹泻疾病的发生流行。

1.1内部因素

腹泻疾病是生猪养殖管理中发生流行率较高的一类传染性疾病的总称，其中对仔猪造成的威胁最为严重，成年猪发病率相对较低，即便出现腹泻，临床症状较为轻微，一般在短时间内恢复健康。……
