摘要：羊口疮病是目前羊养殖领域发生流行较为严重的一类病毒性传染性疾病，任何年龄品种的羊都可以受到病毒侵染，具有极强传染性。羊传染性口疮病虽然造成的死亡率相对较低，但是病毒在养殖场中的传播速度极快，极易造成大面积的羊群患病，对羊群健康生长发育构成不良影响。为有效防范羊口疮病在养殖场中传播流行，需要加强对该种传染性疾病流行特点的有效掌控，结合实际的发病症状，作出妥善有效的诊断，构建完善的防控措施，确保在短时间内控制病情，避免病原传播流行造成严重危害。

Abstract：Sheep aphthous disease is a serious viral infectious disease that has occurred in the field of sheep breeding. Sheep of any age can be infected by the virus and are extremely contagious. Although the death rate caused by infectious aphthous diseases in sheep is relatively low，the virus spreads extremely fast in the farms，which can easily cause diseases in a large area of sheep，and adversely affect the healthy growth and development of the sheep. In order to effectively prevent the spread of sheep aphthous disease in farms，it is necessary to strengthen the effective control of the epidemic characteristics of this infectious disease，combine the actual symptoms，make a proper and effective diagnosis，and construct comprehensive prevention and control measures to ensure that the epidemic control the disease internally to avoid serious harm caused by the spread of pathogens.

0引言

隨着羊规模化养殖的不断推进，各类传染性疾病尤其是外来传染性疾病的引入风险极大增加，养殖户常会面临较为严重的经济损失。羊口疮病一旦在1个养殖场中存在个别患病羊，病原能迅速向着整个群体快速传播蔓延。因此要求养殖管理人员对羊口疮病的发病机理和流行特点有一个大致了解，构建有效的防治措施，降低羊口疮病的发生率，保证羊养殖安全。

1流行特点

羊口疮病是由痘病毒科、副痘病毒属的羊口疮病毒感染引发的一种病毒性传染性疾病，该种病毒在自然环境下具有较强的适应能力和抵抗能力。在养殖群体中，一旦出现上述病毒感染，会造成羊群反复流行，疾病感染时间能持续1年以上。如果环境温度相对较低并且环境干燥，病毒可以存活15年以上[1]。……
