摘要/Abstract

摘要：

近年来，许多研究表明适当降低日粮粗蛋白质（CP）水平是维持断奶仔猪肠道健康及完整性的有效途径，同时对保护仔猪断奶后的肠道具有十分重要的作用。作者简述了日粮CP水平对断奶仔猪肠道屏障功能、肠道黏膜通透性、微生态及致病性大肠杆菌感染的影响，以期为进一步研究日粮CP水平在断奶仔猪上的合理应用提供理论参考。

Abstract:

In recent years,many studies have indicated that appropriate reduction of dietary crude protein (CP) level is an effective way to maintain intestinal health and integrity of weaned piglets,and it is very important to protect the intestinal tract of piglets after weaning.In this paper,the effect of dietary CP level on the intestinal barrier,the permeability of intestinal mucosa,micro ecological and enteropathogenic Escherichia coli infection of weaned piglets were summarized to provide theoretical references for further study of the reasonable application of the dietary CP level on weaned piglets.
