The rate of urea content in tank milk is a standard figure of the milk analysis done for the majority of Walloon farmers. The crude protein ingested is most often the main dietary factor influencing milk urea concentration. To a lesser extent milk urea is also influenced by energy and lactation stage. A normal milk urea rate lies between 200 mg/dL and 350 mg/dL. A content higher than 350 mg/dL indicates a potential waste of nitrogen. On the other hand, a very low urea rate, lower than 200 mg/dL indicates a too low protein content in the ration.
