Present in blood, urine, and milk, the chemical compound urea is the first type of nitrogen excretion in mammals. Testing for urea ranges in dairy cows helps scientists and farmers perceive how successfully nitrogen from feed is utilized in cows’ our bodies, with vital financial implications for farmers when it comes to feed prices, physiological results for cows equivalent to reproductive efficiency, and environmental impacts from excretion of nitrogen in dairy cow waste. Thus, accuracy in testing dairy cow urea ranges is crucial.
Since the Nineteen Nineties, mid-infrared testing of milk urea nitrogen (MUN) has been probably the most environment friendly and least invasive strategy to measure nitrogen use by dairy cows in massive numbers. In a current article within the Journal of Dairy Science, researchers from Cornell University report the event of a sturdy new set of MUN calibration reference samples to enhance accuracy of MUN measurement.
“When a set of these samples has been run on a milk analyzer, the data can be used to detect specific deficiencies in the quality of the MUN prediction that might be corrected by the instrument user or the milk analyzer manufacturer,” defined senior creator David M. Barbano, Ph.D., Northeast Dairy Foods Research Center, Department of Food Science, Cornell University, Ithaca, NY, U.S.. Accurate and well timed MUN focus data “is of great importance for dairy herd feeding and reproduction management,” Barbano added.
Given growing worldwide scrutiny of the environmental results of large-scale agriculture and the economic challenges confronted by farmers, the necessity for correct understanding of nitrogen use within the dairy trade has maybe by no means been extra urgent. This enchancment in milk part testing marks additional progress towards more healthy and extra sustainable agricultural and meals manufacturing practices that may profit producers and shoppers alike.
