农村散养母猪产后瘫痪病因与防治

Causes and Control of Postpartum Paralysis in Rural Scattered Sows

母猪产后瘫痪是生产中易出现的一种代谢性疾病,临床上以生产后肢体麻痹,不能正常站立,或者突然卧地不起,后躯肢体丧失知觉,四肢瘫痪,血钙显著下降为主要特征,该病在高产母猪的群体中发病率最高,不同品种的发病率存在很大的差异性。外来引进的生猪品种出现产后瘫痪的几率要高于本地生猪品种。农村散养户在母猪养殖中由于没有做好科学的饲料搭配工作,母猪在妊娠期间营养物质供给不足,造成身体瘦弱,同时饲料中的钙类元素供给不足,微量元素添加不合理,养殖管理环境不科学,均可造成母猪产后瘫痪的发生。该文主要论述母猪产后瘫痪的发生原因及防治过程。

Post-natal paralysis of sows is a metabolic disease which is easy to occur in production.In clinical practice,it is characterized by paralysis of the post-natal limbs,inability to stand normally,or sudden lying down,loss of consciousness of the hindlimbs,quadriplegia,and significant decrease in blood calcium,the incidence of this disease is highest in the high-yielding sows,and there are great differences in the incidence among different breeds.Imported pig breeds are more likely to have postpartum paralysis than local breeds.Rural free-range farmers in sows breeding due to not doing a good job of scientific feed mix work,sows during pregnancy nutrient supply is insufficient,resulting in body emaciation,at the same time the supply of calcium in the feed is insufficient,the micronutrient is not reasonable,the raising management environment is not scientific,all may cause the sow post-natal paralysis the occurrence.This paper mainly discusses the cause and prevention process of postpartum paralysis in sows.
