    Abstract:

    Bovino spongiform encephalopathy(BSE)is mainly caused by meat and bone meal(MBM).In order to eliminate BSE,it is imperative to develop a method to examine the content of MBM mixed in feedings and fertilizers.The objective of this study was to investigate the feasibility of using near infrared reflectance spectroscopy(NIRS) to determine MBM content in compound fertilizers.By partial least squares(PLS) regression,5 NIRS models were developed from 5 calibration sets,which were of mixed samples of 4 various compound fertilizers with MBM and their collectivity.The determination coefficient(R~2) of 5 calibration sets was,respectively,0.9989,0.9957,0.9977,0.9969,0.9955,and the relative standard deviation(RSD) was,respectively,3.82%,4.07%,3.92%,3.99%,5.13%. The coefficient of determination(r~2) of independent validation sets was 0.9951,0.9981,0.9960,0.9943,0.9884 respectively,and the RSD was 6.74%,2.58%,3.55%,6.17%,7.44% respectively.It is concluded that NIRS can be used as a method to detect MBM content in compound fertilizer.
