奶牛乳尿素氮的研究进展

Abstract

Abstract: Milk urea nitrogen (MUN) is the concentration of urea nitrogen in milk which is an major indicator meaning efficiency of utilization of dietary crude protein .Thus measuring and using MUN is a way to evaluate whether the diet formulation is suitable or not and whether the feeding program is reasonable or not. This paper reviewed the generation mechanism of MUN, the monitoring methods and its affected factors. It also analysed some current problems and predicted its future development. In a word, it is quite useful for the application of MUN to predict ruminant nutrient requirements and scientific diet formulation.

Key words: milk urea nitrogen; dairy; protein; efficiency
