Abstract

There are two purposes of this research: 1) to evaluate the repeatability, precision and accuracy of milk urea nitrogen levels (MUN) using an infrared test, the Fossomatic 4000 MilkoScan analyzer (Foss 4000) at the Prince Edward Island Milk Quality Laboratory (PEIMQL), compared with an enzymatic reference method conducted at the laboratory of the Ontario Dairy Herd Improvement Corporation (ODHIC); and 2) to determine the representativeness of bulk-tank MUN (BTMUN) as a herd representation of the MUN levels.
