The next time you use a particle separator to check the quality of feed delivered to the bunk, make sure you test feed from both ends of the bunk. That’s the advice Jennifer Garrett, nutritionist and technical services manager for Monsanto Dairy Business, gave producers attending the Colorado Dairy Nutrition Conference recently.

Testing the TMR at both ends of the bunk will tell you whether or not all cows receive a uniform ration. When conducting the test on-farm, Garrett often finds one end of the bunk has more fines, or more grain or hay, than the other. Once you discover a problem, use the results to explain the problem to the people who feed the cows.
