Interpretive Summary:

Technical Abstract: The beginnings of the use of modern vibrational spectroscopy in agriculture were with Near Infrared Spectroscopy [NIRS] and the early definitive studies were conducted on forages. These beginnings can be traced by the work accomplished by Agricultural Research Service's National Near Infrared Research Project which began in 1978 and culminated in 1988 with the issue of the first AOAC, International Official Method for protein and Acid Detergent Fiber by NIR. Analyses for which NIRS models were developed include crude protein, moisture/dry matter, permanganate lignin, acid detergent fiber, neutral detergent fiber, acid detergent lignin, in vitro and in vivo digestibility. In this paper we will discuss the requirements of an analytical method as it applies to chemometric methods and NIRS in particular through the answering of three questions and those requirements which differ for the establishment of "Official Methods". We also will look kbriefly at the other vibrational spectroscopies as applied to forage analysis.
