According to one source, non-protein nitrogen (NPN) can comprise 20-30% of the total nitrogen in field grass, highlighting its prevalence and importance beyond conventional protein. So, what are non-protein sources of nitrogen, and why do they play such a significant role in both biology and agriculture?

In mature ruminant diets, non-protein nitrogen can replace up to one-third of the total nitrogen, offering a cost-effective protein source. Understanding what is NPN non protein reveals how these animals convert nitrogenous compounds into usable microbial protein within their specialized digestive system.
