| Abstract: | 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 comparing the precision, reproduction, stability among these three devices the result indicated that the NIRS device made by Changchun Institute is comparable with the other two import devices in all performance. This NIRS device can be widely used to provide accurate and prompt on-line production for mixed feed analysis and the great bencfit will be achived to the feed mills. |
