Urea, which is present in blood, urine and milk, is the major form of nitrogen excretion in mammals. Testing the urea concentration in dairy cows helps scientists and farmers understand how effectively the nitrogen in their feed is used in the cow’s body. Nitrogen contained in cattle excrement. Therefore, it is essential to accurately test the urea concentration in dairy cows.

Since the 1990s, mid-infrared testing of milk urea nitrogen (MUN) has been the most efficient and minimally invasive method of measuring nitrogen use. Dairy cow In large amounts. In a recent article in Journal of Daily ScienceResearchers at Cornell University report the development of a robust new set of MUN calibration reference samples to improve the accuracy of MUN measurements.

“If these sets of samples were run on a milk analyzer, the data could be used to detect specific defects in the quality of MUN predictions that could be corrected by the instrument user or the milk analyzer manufacturer. “I will,” explains senior author David. Dr. M. Barbano, Northeastern Dairy Food Research Center, Faculty of Food Science, Cornell University, Ithaca, NY, USA. Accurate and timely MUN concentration information is “very important for dairy cow breeding and breeding management,” Barbano added.

Given the ever-increasing global oversight of the environmental impacts of large-scale agriculture, Economic challenges The need for accurate understanding facing farmers nitrogen Used in Dairy products The industry is probably more urgent than ever. This improvement in milk composition testing represents further progress towards healthier and more sustainable agricultural and food production practices that benefit both producers and consumers.
