AB  - The objective of this study was to use diffuse reflectance infrared Fourier 
      transform (DRIFT) molecular spectroscopy to investigate the relationship between 
      carbohydrate (CHO) molecular structure spectral profiles (in terms of CHO 
      molecular spectral peak area and height intensities) and CHO chemical profiles, 
      CHO subfractions, energy values, and rumen fermentable organic matter supply in 
      different grains and different types of dried distillers grains with solubles. 
      The various CHO molecular spectral bands included A_Cell (peak area region and 
      baseline  approximately 1485-1188 cm(-1)), mainly associated with hemicellulosic and cellulosic 
      compounds; A_1240 (peak area centered at  approximately 1240 cm(-1) with region and baseline 
       approximately 1292-1198 cm(-1)), mainly associated with cellulosic compounds; A_CHO (peak 
      region and baseline  approximately 1187-950 cm(-1)) associate with total CHO; A_928 (peak area 
      centered at  approximately 928 cm(-1) with region and baseline  approximately 952-910 cm(-1)); and A_860 
      (peak area centered at  approximately 860 cm(-1) with region and baseline  approximately 880-827 cm(-1)), 
      mainly associated with nonstructural CHO; H_1415 (peak height centered at  approximately 1415 
      cm(-1) with baseline  approximately 1485-1188 cm(-1)); and H_1370 (peak height at  approximately 1370 cm(-1) 
      with a baseline  approximately 1485-1188 cm(-1)), mainly associated with structural CHO. No 
      significant correlations were found among A_Cell, A_CHO, H_1415, and H_1370 with 
      CHO chemical and nutrient profiles in the bioethanol co-products. However, CHO 
      molecular spectral intensities of A_1240, A_928, and A_860 were strongly 
      correlated with rapidly degradable CHO fraction (CB1), lowly degradable CHO 
      fraction (CB2), and an unavailable CHO fraction (CC) and could be good 
      indicators. In conclusion, the changes in CHO molecular structures during the 
      processing for bioethanol production were highly associated with carbohydrate 
      degradable subfractions in ruminants.
