mold is present, they should test a
sample for vomitoxin and zeralenone
(those who have sows) and only
vomitoxin (those who have grower -
finisher pigs). Similarly, producers
who want to purchase sprouted wheat
should also test the wheat for
mycotoxins. For further information
on testing for mycotoxins contact
your local feed supplier.

Silo gas
alert issued
The Farm Safety Association
recommends that farmers take
extreme care this fall when filling
silos. Variable growing conditions in
some areas of Ontario may have
created a situation where silo gas may
be more of a problem this year than
others. Climatic conditions play a
large role in the formation of deadly
silo gas, and weather conditions this
summer have caused some farm
safety experts to issue warnings
concerning the gas.
Silo gas or nitrogen dioxide is
produced as a by-product of the
fermentation process that takes place
once plant material is put into a silo.
A variety of climatic stresses on the
plant material during the growing
season can dramatically increase the
possibility of toxic gases forming.
To avoid silo gas, farmers are
advised not to harvest crops imme-
diately after a rainfall. Conversely,
crops damaged by hail or frost should
be harvested as quickly as possible to
avoid build-up of excess nitrate in the
plant material. If weather or other
factors have increased the possibility
of nitrate build-up, plant material
should be cut higher than normal, as
excess nitrates are stored in the lower
portion of corn stalks.
Silo gas may be visible within a
few hours after silo filling and may
be recognized by a bleach -like odour
and may be visible as a yellowish -
brown haze. Dead flies or birds at
the base of the silo may also be an
indicator of the gas.
Once a silo is filled, it should be
sealed and declared off-limits for at
least a three-week period. During
this period of time the silo should not
