Feed and Forage ServicesNear Infrared Reflectance spectroscopy (NIR) is a sophisticated analytical technique for rapidly determining nutrient composition. Utilizing spectral properties of the feed, multiple nutrients are determined simultaneously. First utilized for feed analysis in the late 1970's, it's popularity has blossomed over the last 20 years to make it our most popular service. NIR is recognized by the Association of Official Analytical Chemists (AOAC) as an official method of analysis.
NIR is calibration dependent. Traditionally, calibrations were developed for common feed types by analyzing several hundred to several thousand samples. The chemical information contained in these samples is correlated to spectral properties and a calibration is born. For example, a corn silage calibration is based on samples grown and harvested under varying climatic and geographic conditions. Calibrations built upon many years of information provide the power of being able to accurately analyze samples grown under a wide variety of conditions.
The Feed and Forage Lab at WTAMU uses NIR to analyze the feed types listed in the accompanying (NIR Applicability Chart). When considering NIR services, please check the applicability chart to be sure that your samples are eligible.
