Fermentation
Process
Harvesting forages as silage is a
compromise between reducing
labor requirements and field
losses and reducing losses in
the fermentation process that
eventually will preserve the crop.
Ideal fermentation is dependent
upon decisions and management
practices implemented before
and during the ensiling process.
The primary management factors
that are under the control of the
producer are:
• Stage of maturity of the forage
at harvest
• Type of fermentation that occurs
in the silo or bunker
• Type of storage structure used
and methods of harvesting and
feeding
During the ensiling process,
some bacteria are able to break
down cellulose and hemicellulose
to various simple sugars. Other
bacteria break down simple sugars
to smaller end products (acetic,
lactic and butyric acids). The most
desirable end products are acetic
and lactic acid. As the bacteria
degrade starches and sugars to
acidic and lactic acids, dry matter
is lost.
Attention to details such as speed
of harvesting, moisture content,
length of chop, silage distribution
and compaction can influence
the fermentation process and
storage losses greatly. Efficient
fermentation ensures a more
palatable and digestible feed,
which encourages optimal dry matter
intake that translates into
improved animal performance.
Making consistent, high-quality
silage requires sound management
decisions and attention to details.
Making sure that bacteria
responsible for the production
of acetic and lactic acid grow
and multiply immediately after
storing the forage is important
for maximum quality haylage.
Proper packing of the hay and
voiding of air (oxygen) provides
the environment needed by
bacteria to break down fiber
components and sugars. Oxygen
must be removed from the haylage
to maximize reproduction of acetic
and lactic acid-producing bacteria.
Microbes (bacteria) responsible
for fermentation need anaerobic
(absence of air) conditions
