Current 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 essential financial implications for farmers when it comes to feed prices, physiological results for cows comparable to reproductive efficiency, and environmental impacts from excretion of nitrogen in dairy cow waste. Thus, accuracy in testing dairy cow urea ranges is important.
For the reason that Nineteen Nineties, mid-infrared testing of milk urea nitrogen (MUN) has been essentially the most environment friendly and least invasive approach to measure nitrogen use by dairy cows in massive numbers. In a current article within the Journal of Dairy Science, researchers from Cornell College report the event of a strong new set of MUN calibration reference samples to enhance accuracy of MUN measurement.
“When a set of those samples has been run on a milk analyzer, the info can be utilized to detect particular deficiencies within the high quality of the MUN prediction that may be corrected by the instrument consumer or the milk analyzer producer,” defined senior creator David M. Barbano, Ph.D., Northeast Dairy Meals Analysis Middle, Division of Meals Science, Cornell College, Ithaca, NY, U.S.. Correct and well timed MUN focus info “is of nice significance for dairy herd feeding and replica administration,” Barbano added.
Given rising worldwide scrutiny of the environmental results of large-scale agriculture and the financial 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.
