ABSTRACT
The objective of this research was to characterize new bioenergy feedstocks, in comparison with conventional feedstock, by infrared radiation with advanced molecular spectroscopy in terms of association of molecular structure with nutrient delivery in ruminant livestock systems. This study focused on the effect of molecular structure changes on nutrient delivery to ruminant systems. The updated methods of various lab, animal, and modeling techniques for nutrient delivery study in ruminant livestock systems were reviewed. The molecular spectral analyses used in this study included both univariate and multivariate molecular spectral analyses. The relationship between molecular structural features and truly absorbed nutrient supply was quantified. The research provides information on how inherent structure features in the new types of bioenergy feedstock on a molecular basis affected nutrient delivery in ruminant livestock systems.
