摘要：在羊群饲养过程中，经常看到一些羊非常喜欢采食非食用物质，这种现象就叫异食癖。山羊和绵羊均可见到，尤其是天气干旱或过渡放牧区域，发病率较高。羊发生异食癖后，往往表现为喜欢吞食木片、骨头、瓦块、土块、墙土、煤渣、粪便、抹布、塑料薄膜等异物，这样会影响羊的肠胃健康，诱发各种疾病，严重时还会引起中毒，导致羊死亡。需要了解羊异食癖的原因，根据具体临床表现采取相应的防治措施，保障羊健康。

Abstract：In the process of raising sheep，it is often seen that some sheep are very fond of eating non-food substances. This phenomenon is called pica. It can occur in both goats and sheep，especially in dry weather or over-grazing areas. Sheep tend to like to swallow wood chips，bones，tiles，soil，wall soil，cinders，feces，rags，plastic films and other foreign bodies after the occurrence of pica. This not only affects the health of the sheep's stomach and intestines，but also induces various diseases. In severe cases，it can cause poisoning，leading to death of sheep.Therefore，it is necessary to understand the causes of pica in sheep，and take corresponding prevention and treatment measures based on specific clinical manifestations to ensure that the sheep are in a healthy condition.

0引言

在青黄不接、牧草缺乏的干旱季节，羊就会营养不良，体内容易缺乏维生素和微量元素，消化功能易发生异常，促使羊味觉产生异常，就会采食一些粪便、尿液、土块等非食物东西。有时羊感染疾病后，消化功能也会发生异常，促使羊出现异食癖。随着农业科技发展，农民大量使用塑料薄膜，增加了新型异物采食，导致羊发生食塑料薄膜症。目前对羊造成危害较大的还有啃骨症。羊发生异食癖后，明显影响生长发育和身体健康，必须认真分析发病原因，并采取相应的防治措施，来帮助羊恢复健康。

1发病原因

1.1营养方面

牧草青黄不接的季节，羊无法满足身体生长发育的需要，极易营养不良，尤其在干旱年份，加重牧草缺乏，羊无法采食充足食物，或只能采食干硬不容易消化的饲草，机体不仅缺乏各种营养成分，还引起胃肠功能紊乱和味觉异常，造成羊异食癖[1]。……
