  1. 1IL = interleukin, TNF = tumor necrosis factor.
  2. 2LCF is low-concentrate mixed forage diet with a concentrate to roughage ratio of 46 : 54; HCS is high-concentrate corn straw diet with a concentrate to roughage ratio of 65 : 35; LCS is low-concentrate corn straw diet with the same concentrate to roughage ratio (46 : 54) as LCF.
