AB  - The main objectives of this study were (1) to assess the magnitude of differences 
      among new barley silage varieties (BS) selected for varying rates of in vitro 
      neutral detergent fiber (NDF) digestibility (ivNDFD; Cowboy BS with higher 
      ivNDFD, Copeland BS with intermediate ivNDFD, and Xena BS with lower ivNDFD) with 
      regard to their carbohydrate (CHO) molecular makeup, CHO chemical fractions, and 
      rumen degradability in dairy cows in comparison with a new corn silage hybrid 
      (Pioneer 7213R) and (2) to quantify the strength and pattern of association 
      between the molecular structures and digestibility of carbohydrates. The 
      carbohydrate-related molecular structure spectral data was measured using 
      advanced vibrational molecular spectroscopy (FT/IR). In comparison to BS, corn 
      silage showed a significantly (P < 0.05) higher level of starch and energy 
      content and higher degradation of dry matter (DM). Cowboy BS had lower feeding 
      value (higher indigestible fiber content and lower starch content) and lower DM 
      degradation in the rumen compared to other BS varieties (P < 0.05). The spectral 
      intensities of carbohydrates were significantly (P < 0.05) correlated with 
      digestible carbohydrate content of the silages. In conclusion, the univariate 
      approach with only one-factor consideration (ivNDFD) might not be a satisfactory 
      method for evaluating and ranking BS quality. FT/IR molecular spectroscopy can be 
      used to evaluate silage quality rapidly, particularly the digestible fiber 
      content.
