Development of Rumen Protection Technique and Application of Protein
Rumen bypass protein was the portion of protein in the diet that wasn't degraded by rumen of ruminants during digestion and entered the small intestine directly.The content of rumen bypass protein in the diet was related to the type of protein raw materials.The degradation rate of different protein raw materials in the rumen was very different,and the content of rumen peritoneal protein available was also different.Therefore,proper processing of protein raw materials by rumen protection technology can reduce or even avoid the degradation of microorganisms,so that more proteins can be digested and absorbed through the rumen in the small intestine.In this paper,several common rumen protection technologies and their application effects and existing problems were reviewed.
