摘要：

Near-infrared reflectance spectroscopy (NIRS) has been applied to the determination of starch, protein, and energy in feed grains with a Pacific Scientific research composition analyzer, Model 6250, a Pacific Scientific feed-quality analyzer, Model FQA 51A, and a DICKEY-john grain analysis computer, Model GAC III. The first or second derivative of the log (1/R) algorithm in normal or quotient version gave the best accuracy of analysis by RCA 6250 and FQA 51A. The GAC III uses the log (1/R) algorithm. Accuracies for protein and energy analyses were similar to those obtained by the RCA 6250 or the FQA 51A. © 1990, American Chemical Society. All rights reserved.
