Using Milk Urea Nitrogen to Evaluate Diet Formulation and Environmental Impact on Dairy Farms

Potential use of milk urea nitrogen to abate atmospheric nitrogen emissions from wisconsin dairy farms.

Urinary urea N (UUN) is the principal nitrogen (N) source controlling emissions of ammonia (NH) and nitrous oxide (NO) from dairy manure. The objectives of this study were (i) to study the integrative nature of dietary crude protein (CP) management, secretion of milk urea N (MUN), excretion of UUN, and N emissions from dairy production systems; (ii) to evaluate how associative changes in dietar...

Effect of Milk Urea Nitrogen of Dairy Cows in Relation to Breed

Milk urea nitrogen (MUN) of dairy cows was determined in relation to breed. A total of forty (40) Pabna and red Chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. Live weight of Pabna Cattle (187±14 kg) was higher than that of red Chittagong cattle (174±4 kg). In Pabna cattle milk yield (4.94 kg), minerals (0.15%) a...

Short communication: Evaluation of milk urea nitrogen as a management tool to reduce ammonia emissions from dairy farms.

The purpose of this study was to compile and evaluate relationships between feed nitrogen (N) intake, milk urea N (MUN), urinary urea N (UUN), and ammonia (NH(3)) emissions from dairy farms to aid policy development. Regression relationships between MUN, UUN, and NH(3) emissions were compiled from studies conducted in Wisconsin, California, and the Netherlands. Relative reductions in NH(3) emis...

Feeding Management to Reduce the Environmental Impact of Dairy Farms

Probably no region of the U.S. has experienced greater attention to impact of agriculture on our environment than Florida. Dr. Jack Van Horn, retired from the University of Florida, was an early advocate of research to demonstrate how dairy production could be good stewards of the environment through improved cropping practices and nutritional management. In recent years the Chesapeake Bay has ...
