Effects of supplementation of hairy vetch on the quality of whole crop barley silage

This study was conducted to investigate the effects of hairy vetch supplementation on quality of winter crop silage. There were 4 treatments (addition levels of hairy vetch ; 0, 5, 15, and 30%) with 3 replicates. Experimental silages stored for 40 days at room temperature (20 - 25℃). THe silage crude protein level was improved (P 0.05) in crude fat, NDF and ADF of the silage while hairy vetch supplementation increased. The silage pH was increased (P
