Table 2 Effects of different additive treatments and ensiling durations on the pH value, NDF and ADF contents (g kg−1 DM) of whole crop maize silage

From: Effects of Piromyces sp. CN6 CGMCC 14449 on fermentation quality, nutrient composition and the in vitro degradation rate of whole crop maize silage

  1. CK: control; FU: fungus addition; EN: compound enzyme addition. NDF: neutral detergent fibre; ADF: acid detergent fibre; T: effect of treatment; D: effect of ensiling duration; SEM: standard error of the means
  2. Mean values with different superscript letters in the same column differ significantly (P < 0.05). The interaction between treatment and ensiling duration is significant (P < 0.05), so main effect means are not present. Because of no significant interactions on NDF and ADF contents (P > 0.05), the main effect means are presented, and the differences among the means were examined
