免疫增强剂在养猪业中的应用

Application of immunopotentiator in swine industry

随着养猪业快速发展,养殖集约化程度随之提高,各种疾病入侵的概率提高,传染病频繁暴发并出现几种类型的病原体混合感染,免疫抑制性疾病的风险增加。受各种应激因素的影响,猪的免疫系统紊乱,对疾病的抵抗力下降,疫苗免疫力下降,对病原体攻击的敏感性增加,发病率和病死率提高,对养猪业造成极大的损失。文章综述了目前国内外对猪健康和免疫性能提高效果较好或具有发展潜力的免疫增强剂的相关研究,旨在为养猪业的绿色健康发展提供参考。

With the rapid development of the swine industry,the degree of intensification of breeding has increased,the probability of various diseases invading has increased,the frequent outbreak of infectious diseases and the mixed infection of several types of pathogens have increased the risk of immunosuppressive diseases.Affected by various stress factors,the immune system of swine is disordered,the resistance to disease is decreased,the immunity of vaccines is decreased,the susceptibility to pathogen attack is increased,and the morbidity and mortality are increased,to take a huge toll on the swine industry.The article reviews the current domestic and foreign researches on immune enhancers with better effect or potential for improving swine health and immune performance,aiming to provide a reference for green and healthy development of the swine industry.
