Advance in Determination of Feed Nutritional Quality and Molecular Structure by Infrared Spectroscopy

Infrared spectroscopy(IRS) analysis is a technology that combines techniques such as spectrometry, computer and chemometrics. In the field of feed nutritional value evaluation, IRS analysis technology has the advantages of fast detection,less sample consumption and simultaneous detection of multi-components, and has gradually become a daily testing means in the field of feed production. This paper summaries the research progress on detection of feed nutritional value, molecular structure of nutrient elements and its correlation with the nutrient characteristics of diet and feed ingredient by using IRS analysis technology. In the meantime, the factors affecting the accuracy of determination and the application prospects of IRS analysis technology in feed industry are also elaborated. So as to provide reference for enriching the theory and technology of feed nutrition value assessment.
