摘要: 随着我国养猪业的规模化程度越来越高,各种应激性致病因素的风险不断加大。 应激不仅导致猪的采食量、日增重、肉品质及繁殖率等生产性能下降,还能引起机体粘膜屏障 损伤、炎症反应和免疫抑制,使传染性疫病的暴发风险增高,严重影响了养殖效益和防疫效 果。本文就规模猪场常见的断奶应激、热应激、免疫应激、运输应激和宰前应激等风险因素,从 发生原因、危害、致病机制及防控对策进行综述,为应激性致病风险的控制和应激损伤的缓解 提供依据。

Abstract: With the increasing of pig industry scale in China,the risk of various stress pathogenic factors is serious to host health. Stress not only leads to the decline of production performance,such as feed intake,daily weight gain,meat quality,and reproduction rate of pigs,but also causes the damage of intestinal mucosal barrier, inflammatory response,and immunosuppression of the host. Consequently,the risk of outbreak of infectious diseases is increased that seriously affects the breeding efficiency and epidemic prevention effect. This paper reviewed the common risk factors in scale pig farm,such as weaning stress,heat stress,immune stress,transportation stress,and pre ? slaughter stress. We focused on the causes,hazards,pathogenesis and prevention and control techniques of various stress,so as to provide basis for the control of stress?induced disease.
