Pasteurized Waste Milk Analysis

This analysis is available to producers with on-farm pasteurization units to determine proper unit function. Many dairy producers pasteurize waste milk and feed it to their calves. If on- farm pasteurization unit malfunctions, calves may become sick and die before the producer realizes what happened. AgSource provides this test to minimize or prevent these losses. This analysis was developed in conjunction with the UW Ag Research Station in Marshfield, Wis.
