Conteúdo:  Near infrared reflectance spectroscopy (NIRS) is a nonconsumptive, instrumental method for fast, accurate, and precise evaluation of the chemical composition and associated feeding value attributes of forages and other feedstuffs provided the proper procedures are followed. Each of the major organic feed components has absorption characteristics (due to vibrations arising from the stretching and bending of H bonds associated with C, O, and N) in the near infrared region that are specific to the component. These absorption characteristics primarily determine diffuse reflectance, which gives us the means for assessing composition. This handbook is intended to provide an overview of the history of NIRS use for forage quality analysis, a summary of available equipment and computer software, recommended conventional and NIRS procedures for analysis of forage quality, an explanation of how and why NIRS functions, recommended NIRS instrument calibration (including equation development, validation, monitoring and transfer), progress in NIRS technology transfer, and consideration of future applications and certification procedures for NIRS technology. Readers may find that specific chapters meet their informational needs, or they may wish to read all chapters, appendixes, and supplements sequentially for a complete interpretation of the subject.
