4.1. Chemical composition
The DM and WSC contents of MO and MO-FJLB silages
were higher than those of FJLB and CO silages, indicating that
molasses increased silage DM and WSC. WSC residues did not
differ between CO and FJLB silages; however, lactic acid
content was lower in the CO silage than in the FJLB silage,
suggesting that microorganisms in CO silages may compete
with LAB for WSC to produce another end product. Saccharolytic
clostridia ferment sugar and lactic acid to produce
butyric acid, which may have caused the high butyric acid
content in the CO silage. Weinberg et al. (1993) suggested
that the higher residual WSC content of silage indicates
smaller DM losses during fermentation, producing better
silage quality. However, low WSC content is an important
factor for aerobic stability in silage; yeast and mold metabolize
residual WSC, which results in rapid deterioration
