摘要
通过使用三种型号的近红外分析仪:Neotec 51A、Trebor-70和长春光机所研制的近红外分析仪测定了58个蛋鸡配合饲料样品的水分、粗蛋白、粗纤维、粗脂肪、赖氨酸、蛋氨酸和代谢能等七项指标,比较了三种近红外分析仪的测定精度、重复性和稳定性。结果认为:长春光机所研制的近红外分析仪对配合饲料营养成份的测定精度、重复性和稳定性等方面均达到了国外同类产品的技术水平,且成本造价低,可以在饲料工业上推广应用。
Three types of Near Infrared Reflectance Spectroscopy (NIRS) device, Neotec 51A. Trebor-70 and the NIRS analyzer were made by Changchun Institute of Optics and Fine Mechanics that were applied to measure moisture, protein fiber fat lysine, methionine, metabolism energy (ME) of 58 layer feed formulated in laboratory. By compari- ng the precision, reproduction, stability among these three devices the result indicated that the NIRS device made by Changchun Insti- tute is comparable with the other two import devices in all perfor- mance. This NIRS device can be widely used to provide accurate and prompt on-line production for mixed feed analysis and the great be- ncfit will be achived to the feed mills.
