Near infrared reflectance spectroscopy (NIRS) is a newer technology being adopted for use in the on-site determination of nutrient composition of feedstuffs and finished feeds since it requires minimal sample preparation, allows for high sample throughput, and has a low cost per sample.
It includes visible near-infrared (Vis-NIR) and Fourier transformed near-infrared (FT-NIR) spectroscopies. The most significant advantages of this technique over previous GMO research processes are its low cost, little to no sample preparation, and less time-consuming procedures . Another advantage is that there are no chemicals used in …
