Abstract
This study examined the effect of moisture level at ensiling on fermentation characteristics of barley and rye silage. The moisture levels, 60 (low; LM), 70(medium; MM) and 80% (high; HM), were controled by adding water or pre-wilting. Barley silage had higher pH and latate:acetate ratio in LM than the other treatments, but those of rye in MM were higher. The concentrations of lactate, total FA and acetate in HM were higher than the other treatments, but propionate concentration in LM was higher than HM. Total N concentrations of barley and rye were highest in MM and LM, respectively. The $NH_3-N$ concentration and total N:$NH_3-N$ ratio of barley were higher in HM than those in LM and MM. With increasing moisture content, buffering capacity of barley and rye silages increased, whereas decreased by increase of pH. There was a negative correlation between moisture content vs. pH of barley and rye silages. However, moisture content vs. the concentrations of total VFA and $NH_3-N$ and the ratio of total N:$NH_3-N$ had a positive correlation. Tn conclusion, the ideal moisture content of barley and rye for silage was 70-80%, but silage quality could be rapidly decreased by pre-wilting to 60% moisture content.
