仔猪高死亡率腹泻病因探讨

Discussion on the pathogenesis of high mortality piglet diarrhea

2010年4月以来,全国各地先后出现高死亡率吮乳仔猪腹泻,以冬春寒冷季节多发、持续时间长、高死亡率为特征,日龄越小死亡率越高,用药物及生物制剂均无法有效控制,给养殖业带来巨大的经济损失。按照流行性腹泻病毒感染、霉菌毒素及中毒等采取相应的防治措施,效果均不明显。按中兽医整体观念、辨证论治,将两方面病因有机结合起来,分析该疾病的病理机制,采用中药复方进行临床验证,取得较好的防治效果,为该病的预防和治疗提供了新的思路与方法。

Considering the whole concept and differentiation of traditional Chinese veterinary medicine, we combined with the cause in two aspects（PEDV, Mycotoxin Poisoning） to investigate the action mechanism of high mortality piglet diarrhea and developed traditional Chinese medicine. The results dedicated effective of prevention and treatment on the disease after clinical verification. It provides new ideas and methods of prevention and treatment for the high mortality piglet diarrhea.
