title: Nutrient content and nutrient availability of sorghum wet distiller's grain in comparison with the parental grain for ruminants.
abstract: BACKGROUND
  The present study aimed to compare wet sorghum distiller's grain (WSDG) with sorghum grain (SG) in terms of: (i) chemical composition; (ii) in situ rumen degradation kinetics of organic matter (OM) and neutral detergent fiber (NDF); (iii) crude protein (CP) sub-fractions; (iv) in situ disappearance at 12 and 48 h; and (v) energy values. The WSDG intestinal digestibility (ID) of undegradable crude protein (UCP) was compared to soybean meal (SBM).
  
  
  RESULTS
  Compared to SG, WSDG exhibited: (i) lower (P < 0.01) dry matter and non-fiber carbohydrate content, whereas the other chemical components were higher (P < 0.01); (ii) higher (P < 0.01) degradation rates of OM and NDF and lower (P < 0.01) degradable fraction of OM and NDF; (iii) lower (P < 0.05) contents of CP sub-fractions A, B1 and B2, and higher (P < 0.05) contents of B3 and C; (iv) lower (P < 0.05) protein disappearance at 12 and 48 h and higher UCP; and (v) lower (P < 0.05) energy content. The ID of UCP for WSDG was lower (P < 0.05) compared to SBM.
  
  
  CONCLUSIONS
  The WSDG as a supplement provides a good source of energy. To enable its use as a protein supplement, further studies should be performed. © 2016 Society of Chemical Industry.
