摘　　要：饲喂高精料饲粮是提高反刍动物饲粮能量水平的常用策略,但这通常会导致急性或亚急性瘤胃酸中毒及后肠道酸中毒,从而危害其胃肠道健康。高精料饲粮饲喂反刍动物可影响粗饲料的消化利用,削弱胃肠道微生物菌群的功能,并降低胃肠道上皮的吸收和屏障能力。本文主要综述了高精料饲粮对反刍动物胃肠道内微生物区系和上皮的影响及相应调控措施,以期为提高胃肠道健康水平提供参考。Feeding high concentrate diet is a common strategy to increase the energy level in ruminant diets,but this usually leads to acute or subacute rumen acidosis and posterior intestinal acidosis,thereby endangering its gastrointestinal health.High concentration diets fed to ruminants can affect the digestion and utilization of roughage,weaken the function of gastrointestinal microflora,and reduce the absorption and barrier capacity of gastrointestinal epithelium.In this paper,the effects of high concentration diet on the microbial flora and epithelium in the gastrointestinal tract of ruminants and the corresponding regulation measures were reviewed in order to provide references for improving the health level of the gastrointestinal tract of ruminants.
