AB  - Corn starch played a critical role in maintaining energy supply for high milk 
      yield. The objectives of this research were to disclose the starch and 
      carbohydrate-related biopolymers degradation in three newly developed corn lines 
      (LM10, LM01 and LD999) during rumen incubation, and detect relationships between 
      molecular structures and starch degradation. Attenuated Total Reflectance 
      Fourier-transform Vibrational Molecular Spectroscopy (ATR-Ft/VMS) was applied to 
      reveal molecular structure conformations that were associated with major 
      nutrients macro-biopolymers. Line LM01 was greater (P < 0.01) in peak heights and 
      areas of carbohydrate (CHO) related spectral than LM10 and LD999 (P < 0.01). Line 
      LM01 had greater rumen degradable dry matter and starch than LM10 and LD999 
      (P < 0.05). During 48 h rumen incubation, absorbance intensities of CHO peak 1 
      and peak 3 decreased linearly (P < 0.01), but absorbance intensities of CHO peak 
      2 increased, non-structural CHO related spectral absorbance intensities decreased 
      linearly (P < 0.01). Correlation analysis showed that CHO associated spectral 
      were positively correlated to ruminal dry matter and starch degradability 
      (P < 0.10). The results inferred that the molecular spectral features of newly 
      developed corn lines played a more important role in determining starch 
      degradability.
