摘　　要：本研究建立了一种依据红外光谱原理快速测定尿素氮仪器的校准方法,并对校准后的仪器在牧场应用的大量测定数据进行了分析。分析表明,一是奶牛尿素氮值受季节因素的影响,夏季会偏低一些;二是尿素氮测定值受原料乳中脂肪含量的影响,当乳脂率在5%~14%区间时,二者会呈现正相关性。This study established a kind of milk urea nitrogen(MUN) calibration procedure using infrared spectrometry instrument.By analyzing the data of MUN with applying infrared spectrometry instrument on dairy farm, the results showed that the season had effect on MUN, MUN in summer was lower. The fat content had effect on the testing of MUN with using infrared spectrometry instrument,when the fat content was between 5% to 14%,presenting positive correlation.
