The present study aimed to determine the microwave irradiation (MIR)-induced changes in protein molecular structures in barley (Hordeum vulgare) grains in relation to the truly absorbable protein nutrient supply to ruminant livestock systems. Samples from hulled and hulless cultivars of barley, harvested in consecutive years from four replicate plots, were evaluated. The samples were either kept raw or were irradiated with microwaves for 3 min (MIR3) or 5 min (MIR5). The truly absorbable protein nutrient supply to ruminant livestock systems was evaluated using the DVE/OEB system (DVE, truly absorbed protein in the small intestine; OEB, degraded protein balance). Molecular structure changes as a result of processing were revealed by vibrational molecular spectroscopy in the mid-infrared electromagnetic radiation region.
