摘　　要：仔猪早期断奶是现代集约化养殖系统中提高母猪生产效率的重要策略。早期断奶策略缩短猪的屠宰周期,提高母猪的繁殖性能,已普遍应用于猪生产。由于生理、环境和社会挑战等多重压力因素,仔猪断奶后综合征常发生在断奶早期。其特征通常是短暂性厌食、肠道菌群失调、严重肠道损伤、感染和腹泻,损害仔猪的抗病能力。断奶后腹泻(PWD)对仔猪健康构成严重威胁,导致高死亡率,影响经济收益。制定合适的策略来防治PWD对畜牧业和粮食安全至关重要。该文综述PWD的发病诱因、管理方法、免疫方案以及防治对策。Early weaning of piglets is an important strategy for improving the production efficiency of sows in modern intensive farming systems.The early-weaning strategy,which shortens the slaughter cycle of pigs and improves reproductive performance in sows,has been generally applied in pig production.However,due to multiple stressors such as physiological,environmental and social challenges,postweaning syndrome in piglets often occurs during early weaning period.It is characterized by transient anorexia,intestinal dysbacteriosis,severe intestinal injury,infection and diarrhea,which impair the disease resistance of piglets.Post-weaning diarrhea(PWD)is a serious threat to the health of piglets,leading to high mortality and affecting economic returns.Therefore,the development of appropriate strategies to prevent PWD is critical to livestock and food security.This article reviewed the causes,management methods,immunization programs and prevention and treatment strategies of PWD.
