Extract

Homolactic bacteria have been used to inoculate silages and improve their fermentation. Inoculation with these microbes has increased the rate and extends of lactic acid production in silage and decreased proteolysis and production of volatile organic acid. Wilting of high moisture forages prior to ensiling usually enhances preservation and intake responses of cattle fed silage. Wilting creates an ensiling environment that is conducive to a restricted proteolysis and fermentation, and the resulting silage is typically higher in water soluble carbohydrate (WSC) and lower in fermentation acids. The microorganisms used in silage inoculants depend on a high level of moisture for growth. Pahlow and Weissbach (1996) reported that only 10% of the total population of epiphytic lactic acid bacteria (LAB) on grasses grew on modified, selective agar with an water activity (aw) of 0.952 (forage with a DM content of 50%), suggesting that epiphytic LAB were not very osmotolerant. However, Lucerne is often wilted to concentrations above 30% DM before ensiling to reduce the chances of clostridial fermentation and In these silages, it may be speculated that use of osmointolerant inoculants can include two Excellences of wilting and inoculants to make better silage. The aim of the present study was to assess the effects of wilting and inoculants on Lucerne silage quality.
