Description
Alfalfa (Medicago sativa L.)was ensiled with or without previously fermented juice (PFJ) after wilting for 0, 3, 6 and 24 h. They were ensiled in 900ml glass bottles at 400g/800cm3 and preserved at 25°C for 45 d. The moisture content of the silages were 810, 730, 690 and 580g/kg, respectively. The PFJ was prepared by macerating 200g of freshly harvested alfalfa with 1,000ml of water, filtering through double cheese cloth, adding 20g/l sucrose and incubating anaerobically at 30°C for 2 d.
