Winter Feed - Act Now
There will be two major issues this winter in terms of animal feed – quantity and quality - according to Teagasc advisers in Ireland.At
the moment securing enough winter feed is
the key issue. It is important to act now. It will
cost a lot more to fill the deficit if you are
facing the back wall of the silage pit next
January.
The first step is to establish how short you are
in terms of feed. Estimate how much silage you
need over the winter, i.e., the number of
animals to be fed and the length of the winter.
Secondly, calculate the quantity of forage
presently on the farm including pit silage
(grass, maize and whole crop), bales, straw,
hay and forage crops.
Once you have at least 40 per cent of your silage
requirements for the cows and 30 per cent of your
silage requirements for the young stock, there
are options. There is no single action that will
sort the deficit; it requires a number of
initiatives to deal with the problem.
The demand for silage is reliant on the number
of stock to be housed and on the length of the
winter. Actions can be taken on both sides of
this equation. Setting the farm up to allow for
extended grazing this autumn and early
turnout next spring will be key to reducing the
demand for winter feed. The weather will
dictate a lot but it’s important to plan for a
good autumn and spring so that you can
maximise on the benefits. Is there surplus stock
on the farm that could be sold? This will lower
demand.
On the supply side, consider taking out surplus
bales in August should grass growth increase.
But remember you will also need to start
increasing farm cover from mid August.
Forage rape may be an option for some
farmers on dry ground but it’s too late for kale.
Buying silage is an option but only where it’s
good value and the quality of it is known.
Relative to current feed prices, good quality
silage (72 DMD) is worth up to €31/bale, while
moderate quality silage (65 DMD) is worth up
to €28/bale, delivered prices. Pitted silage is
worth €3-4/tonne more than bales. First-cut
silage baled in July, which is six to seven weeks
later than normal, will be very low in
digestibility and similar to straw in feeding
value.
Alternative forages and wet feeds may be an
option for some. Good quality maize silage is
worth €54/tonne, while good quality whole
crop cereal silage and fodder beet are worth up
to €74/t and €41/t, delivered. It is important to
note that some of these feeds will be of
moderate to poor quality this autumn and you
must know the quality before purchasing.
While wet feeds such as brewers’ grains may be
an option, availability of some of these will be
an issue. Grain storage on farm will be an
option for some. Treatment costs are
approximately €35/t, including the additive,
processing, storage and losses. Remember that
these feeds will need to be balanced for protein
and minerals, and storage facilities will be
needed.
In many cases buying bad quality silage will be
a more expensive option than buying meals
and feeding it with a restricted quantity of
silage. In 2009, Moorepark Research Centre fed
the dry cows 6kg DM of silage plus 3kg DM of
straw and 3.5kg of ration and dry cow
minerals. Supplementation rates can be
increased/decreased, depending on silage
supply.
