Technologies for restricting mould growth on baled silage
End of Project ReportSilage is made on approximately 86% of Irish farms, and 85% of these make some baled silage.
Baled silage is particularly important as the primary silage making, storage and feeding system on
many beef and smaller sized farms, but is also employed as a secondary system (often associated
with facilitating grazing management during mid-summer) on many dairy and larger sized farms
(O’Kiely et al., 2002).
Previous surveys on farms indicated that the extent of visible fungal growth on baled silage was
sometimes quite large, and could be a cause for concern. Whereas some improvements could come
from applying existing knowledge and technologies, the circumstances surrounding the making
and storage of baled silage suggested that environmental conditions within the bale differed from
those in conventional silos, and that further knowledge was required in order to arrive at a secure
set of recommendations for baled silage systems.
This report deals with the final in a series (O’Kiely et al., 1999; O’Kiely et al., 2002) of three
consecutive research projects investigating numerous aspect of the science and technology of
baled silage. The success of each depended on extensive, integrated collaboration between the
Teagasc research centres at Grange and Oak Park, and with University College Dublin. As the
series progressed the multidisciplinary team needed to underpin the programme expanded, and this
greatly improved the amount and detail of the research undertaken.
The major objective of the project recorded in this report was to develop technologies to improve
the “hygienic value” of baled silage. Specifically, the stated aims were to:
1. Characterise the mycobiota on baled silage in Ireland
2. Enhance our understanding of the fermentation kinetics (and the unique combination of
factors regulating them) peculiar to baled silage
3. Develop the capability to elucidate the mechanisms of gas entry to and exit from wrapped
bales
4. Develop improved plastic and sealing methodologies
5. Identify strategies to successfully produce baled silage with a reduced content of mould and other undesirable micro-organisms
