Abstract

Previously a new method for measurement of urea, based on the generation of volatile CO 2 pressure from the enzymatic hydrolysis of urea, was identified and used succesfully. The technique is robust, accurate, inexpensive, and fast enough to be used on-line in the milking parlor. In this paper an on-line sensor using this technology to measure urea in milk is described and evaluated. The precision of the sensor in milk (±0.7 mg/dl urea N) is within the objectives of the research (±1.0 mg/dl urea N). Different sources of variation in milk urea are quantified in order to understand better how the sensor may be applied on the dairy farm and how observed milk urea values might be interpreted.
