Abstract
A second cut from a mixed sward of red clover, timothy
and meadow fescue was prewilted and harvested with a
precision chopper. The grass had a dry matter (DM)
concentration of 357 g kg-1, while water soluble
carbohydrates were 66, crude protein 122, and D-value 596
g kg-1 DM. The grass was ensiled without an additive
(control), with Lactobacillus buchneri, with
Lactobacillus plantarum or with AIVr2Plus. Addition of
AIVr2Plus restricted silage fermentation as judged by
high residual sugar and low lactic acid concentrations.
Plantarum silages had a homolactic fermentation profile
with low pH, high lactic and low acetic acid
concentrations. Buchneri silages had a heterolactic
fermentation profile with high acetic and propionic, and
low lactic acid concentrations. There were no
statistically significant differences between treatments
in biochemical methane potential of the silages. DM
losses during ensiling were 27, 35, 10, and 14 g kg-1 DM
for Control, Buchneri, Plantarum and AIVr2Plus silages,
respectively. The losses after silo opening during 259 h
aerobic phase were 42, 3, 143 and 9 g kg-1 DM,
respectively. The high DM loss during the aerobic phase
in the Plantarum silages was related to high counts of
enterobacteria and fungi.
