Thanks to a grant, Maryland dairy producers will soon have a new tool to help them determine how much of the protein fed cows is utilized by the cows and how much is excreted in manure in urine as excess nitrogen.
The University of Maryland received a $788,845 grant from the USDA Natural Resources Conservation Service to use milk urea nitrogen (MUN) testing to help reduce nitrogen pollution of the Chesapeake Bay. The testing program will be carried out in partnership with the Maryland Department of Agriculture and VirginiaTechUniversity. Routine MUN testing will start at milk processing plants in Maryland and Virginia. The program may be expanded to Pennsylvania as well.
