Extract

The spreading of slurry and other livestock wastes onto grassland is used as a means of recycling nutrients. Often these areas of grassland are subsequently used for silage production and there has been concern that the timing of slurry application may influence the outcome of the silage fermentation (O'Kiely et al. 1993). The application of slurry alters the microbial flora of the herbage and some of those added bacteria are associated with poor silage fermentations (Ostling and Lindgren, 1991).

The objective of the experiment was to examine the effect of the timing of a high level of slurry application to grassland on survival of enterobacteria, lactic acid bacteria and Clostridia on the herbage, and subsequent effects on it's fermentation during ensilage.
