摘要:生猪养殖过程中,腹泻是一种常见的消化道疾病,尤其在仔猪中最为常见。腹泻疾病会显著降低生猪对饲料营养物质的消化吸收利用,降低生猪生产性能,一些严重的腹泻疾病会导致生猪死亡,对生猪养殖的经济效益产生了严重的影响。生猪腹泻疾病的原因主要包括细菌感染、病毒性感染、寄生虫感染及饲养管理不当等。该文将对生猪腹泻疾病的流行特点、症状及防治措施进行介绍,旨在为生猪的健康养殖提供帮助。

Abstract:Diarrhea is a common digestive tract disease in pig breeding,especially in piglets. Diarrhea diseases can significantly reduce the digestion,absorption and utilization of feed nutrients and reduce the production performance of pigs. Some serious diarrhea diseases will lead to the death of pigs and have a serious negative impact on the economic benefits of pig breeding. The causes of diarrhea in pig breeding mainly include bacterial infection,viral infection,parasitic infection and improper pig feeding and management measures. The paper will introduce the epidemic characteristics,symptoms and prevention measures of diarrhea diseases in pig breeding,in order to provide help for healthy pig breeding.

Keywords:pig,diarrhoeal diseases,epidemic characteristics,clinical symptoms,prevention and control measures

0引言

隨着生猪养殖密度和数量地不断增加,生猪养殖中的病害问题也逐渐凸显。其中,腹泻是一种常见病,在生猪各日龄阶段,各养殖品种中均会出现,尤其在仔猪养殖中最常见。冬春季节,由于环境温度的急剧变化,容易引起猪应激,诱发腹泻。在实际养殖中,导致猪腹泻的因素还有很多方面,如细菌、病毒和寄生虫病,饲养管理不恰当及饲料原料品质低下等,均可引起消化道疾病,导致腹泻。饲养管理人员应早预防、早发现、早治疗,尽量在短时间内控制生猪腹泻,降低经济损失。本文将对生猪腹泻疾病的流行特点,病理变化及防治措施进行介绍,以期为生猪腹泻疾病的科学防治及我国生猪养殖产业的科学发展提供帮助。
