SAFETY TIPS:
• The greatest danger period is three
to four weeks after filling the silo —
stay out if possible.
• If you must enter the silo where gas
may be present, use a self-contained
breathing apparatus and follow
confined space entry procedures.
• Post warning signs to inform others
of danger.

WHAT'S NEW
DACO LABS TEST
HOME FEED MIXING
Livestock producers who make their
own feeds on the farm can be assured of
accurate and consistent rations, says Art
Putz of Daco Laboratories.
The keys are: having feedstuffs
analyzed, getting rations formulated,
calibrating meter mills regularly, ensur-
ing accurate weights and mixing time
with batch mixers, and having finished
feeds assayed.
Daco, which offers customers cali-
bration and feed testing services, re-
cently started its Feed Certification
Program to ensure the consistency of a
batch of feed.
The service was a response to the
concern about residue in pork from feed
medications.
Nine samples are taken during the
time it takes to unload a batch. Or,
where meter mills are used, the nine
samples are taken over 15 to 30 minutes.
Then the co -efficient of variation (CV),
set at +10 per cent or less, is calculated.
To date, Daco reports, 75 feed -
manufacturing systems have been
checked, 33 of them meter mills and 42
of them mixers of various types.
Daco adds that 30 of the meter mills
were under 7 per cent CV. One mill was
more than 10 per cent CV because of a
malfunctioning proportioner, and the
other 2 mills ran out of an ingredient
during testing.
After testing the 42 mixers, 4 were
found to be over the 10 per cent CV
limit. Daco offered to re -test, but before
the second test changes were suggested
for the loading sequence of feed ingredi-
ents and/or longer mixing times.
The length of the mixing time seems
to be the most important factor to
achieve a uniform ration, says Art Putz.
And horizontal ribbon or paddle mixers
should not be overloaded. For example,
material should only be loaded to the
height of the shaft or a little bit above.
Three of the four mixers, Putz says,
were re -tested, with results under 10 per
cent CV. The producer with the fourth
mixer said he was not prepared to make
half a batch with his ribbon mixer, and
that his pigs were doing well. He ac-
commodated the mixer by starting to
feed at different pens each time.0
