Farm Table says:

Where high levels of supplements are fed, the protein content of the diet needs to be assessed.  It should be noted that milk urea levels are of limited use in a pasture-based systems.

This webpage was produced by DairyNZ in 2013 and contains information on milk urea as an approximate indicator of the amount of crude protein in a cow’s diet.

The webpage includes a table on the recommended crude protein requirements and subsequent approximated milk urea values at different stages of lactation, as well as links to discussions such as Busting Milk Urea Myths and The Facts of Milk Urea.

It also includes a link to a fact sheet with more detailed information, with the following key sections:

  • What is milk urea?
  • Interpreting MU;
  • Protein requirements and associated milk urea values;
  • Environment (urinary nitrogen concentration and environmental considerations).

In conclusion, this webpage and the associated content provides information on milk urea, how it is measured and assessed, and when the levels can be used to assess protein content in the diet.
