奶牛生产中所用的尿素氮通常是指乳尿素氮(milk urea nitrogen,MUN)。MUN 主要来源于瘤胃降解蛋白。测定 MUN 对保持奶牛能氮平衡、发挥生产潜能及最大效率利用饲料蛋白质、降低成本等有着深远意义。 该试剂盒利用尿素在脲酶的作用下水解产生氨离子和二氧化碳,氨离子在碱性介质中与酚显色剂生成蓝色物质,该物质的生成量与尿素含量成正比。通过于625nm处检测该有色物质含量进而得出牛奶中尿素氮(MUN)含量。
In dairy cattle production, the urea nitrogen commonly referred to is milk urea nitrogen (MUN). MUN primarily originates from rumen-degradable protein. Measuring MUN holds significant importance for maintaining the energy-nitrogen balance in dairy cows, unleashing their production potential, maximizing the efficient utilization of dietary protein, and reducing costs. This kit utilizes the hydrolysis of urea by urease to produce ammonium ions and carbon dioxide. In an alkaline medium, the ammonium ions react with a phenol chromogenic agent to form a blue-colored substance, the amount of which is proportional to the urea content. By detecting the concentration of this colored substance at 625 nm, the milk urea nitrogen (MUN) content is determined.
