禁抗后仔猪细菌性腹泻的临床诊断与防治

Clinical diagnosis and control of bacterial diarrhea in piglets after ban on antibiotics

为了促进食品安全和养猪业的健康发展,禁止在饲料中使用促生长抗生素势在必行。随着我国的饲料禁抗相关法规的推行,饲料企业被严格禁止在饲料生产过程中加入抗生素,这也导致了猪场疾病尤其是肠道疾病的高发,而仔猪肠道发育未完全,免疫系统未发育成熟,更容易发生严重的腹泻甚至死亡。文章对几种常见的仔猪细菌性腹泻疾病进行了回顾,病原包括大肠杆菌、沙门氏菌、魏氏梭菌,讨论了它们的临床症状与防控措施,为猪场在防控这些细菌性腹泻提供参考。

To promote food safety and the healthy development of the pig industry,it is imperative to stop the use of growth-promoting antibiotics in feed.With the implementation of the law and regulations of ban on antibiotics in China,feed companies are strictly prohibited from adding antibiotics in the feed production process,which has also led to a high incidence of on-site diseases in pig farms,especially intestinal diseases.Piglets have incomplete intestinal development and immune system is immature so they are more prone to severe diarrhea and high mortality.This article reviews several common infected bacterial diarrhea diseases in piglets and the pathogens include Escherichia coli,Salmonella,Clostridium welchii,discussing their clinical symptoms and control measures,to help pig farms in preventing and controlling of those bacterial diarrhea.
