Sample preparation of feeds and forage for NIR analysis

The feed quality has a decisive influence on the productivity of livestock farming. However,  high-quality forage considerably adds to the costs of stock breeding. Consequently, economic considerations focus on the quality and quantity of the components used in the production process. This includes reliable analyses of feedstuff and ingredients from receipt of goods to final inspection as the best way to ensure a balanced feeding of the animals while keeping cost and profit orientation in focus.
Near Infrared Spectroscopy (NIR) is the most important analytical method for the determination of protein content, moisture, fat and ash in feeds and forage. The advantage over classical methods such as Kjeldahl is the simultaneous determination
of several parameters. Moreover, NIR spectroscopy is a quick method, which requires neither consumables nor reagents.
