The evaluation of nutritive value in alfalfa silage through Near Infrared Reflectance Spectroscopy

Using Alfalfa silage as research materials, the research discusses the prediction of Near Infrared Spectrocropy (NIRS) on chemical compounds 121 samples of alfalfa silage. The results are as follows: the NIRS models of DM, CP, WSC have been set up. The RPD value for cross validation and validation are all above 2.5. The results show that the NIRS can accurately evaluate nutritive value of alfalfa silage.
