This study was carried out to examine the effect of pre-wilting time at different stage of harvest on change in the moisture content of whole crop barley(WCB) and its silage quality. Results showed that moisture content of whole crop barley could reach to 65%, which is an optimal content for making silage, by pre-wilting whole crop barley for 4 hours after harvest at either 20 days or 30 days after heading. As the feed value of silage, its protein content, TDN and RFV was high but ADF was low at an optimal level of moisture content, 60~65%. The pH and organic acid content, criteria for evaluating silage fermentation, were quite varied by the changes in moisture content. The highest content of lactic acid and low content of acetic acid and butyric acid were measured at the level of an optimal moisture content, indicating an efficient silage fermentation. In conclusion, 4 hours of pre-wilting after harvesting WCB could be an efficient way to increase the stability of silage under aerobic condition result in improving the quality and feed value of silage.
