Near-infrared spectroscopy (NIR) is a technology that measures the absorption of chemical bonds in raw materials. It is which chemical bonds are in the raw material and in which wave field. This information can be used and compared with in vivo actual measurements and thus get a prediction for various aspects of raw materials. These include the chemical content of the raw material, the digestibility of nutrients, the composition of nutrients such as amino acids and fatty acids to name a few. The NIR device actually gives the fingerprint of the raw material.

This report discusses the use of NIR and highlights the state of knowledge. The process of making the NIR forecast model will be discussed, what to watch out for and keep in mind. Experiments are cited where NIR forecast models have been developed for various raw materials and animal species and the accuracy of such models has been assessed.

Near-infrared spectroscopy (NIR) is a technology that measures the absorption of chemical bonds in materials. This information can be used and compared with in vivo actual measurements to get a prediction for various aspects of materials. This includes the chemical content of organic raw materials, the digestibility of nutrients through animals, the composition of amino acids and fatty acids to name a few. 

This report discusses the use of NIR and highlights the state of knowledge. Covers the process of making a NIR model and the pros and cons of different methods. The report discusses existing research where NIR models have been developed for various raw materials and animal species and evaluates the accuracy of those models.
