The forage was allorved to wilt in the srvath to approximately 300 or 500 g/kg dqy nmfter (DM) content and the,n it was e,nsiled wi&out firthsr Eeahent The number of lactic bacteria“ mol4 and yeast as well as pH and concenhation of lactic acid were indikative of adequate prcsernation Thc majority of the initial content of coumeshol disappeared during 50 days ofensiling, but some was still dctected after 150 days.
