TO CONTROL COCCIDIA
water from the drinker. If it is set
too low, the bird will come at it
sideways or duck down to get it, and
about a handful of water will fall
into the litter each time. However,
the lines need to be set low enough
so the smallest members of the flock
can still reach the water.
The second part of proper
management is maintaining clean
water lines. Clean nipples are
less likely to leak into the litter.
Hess recommended cleaning the
water lines between each flock by
shocking it with a disinfectant, and
then thoroughly rinsing it out. When
birds are in the house, it's possible
to keep the lines clean by running
citric acid, vinegar or another
poultry water treatment.

Ventilation management
Managing ventilation to keep litter
dry is trickier. Hess said it's easy to
say growers need to keep their fans
or heaters running constantly to
keep litter dry, but it's hard for the
grower to spend the money to do it.
Really, it's a balancing act for each
grower depending on the environmental conditions.
Hess also said it's important
to remember that just because the
temperature inside the house is right,
it doesn't mean the moisture level or
humidity is right, too. He recalled

are denied a wet, warm
environment. Keeping litter

one instance while visiting a farm in
a cool climate where the temperature
inside the house was great, and the
grower was saving money by not
running the fans. However, the lack
of air circulation and excess of moisture created a situation where water
was condensing on the ceiling and
dripping down onto the litter.

Tilling to remove litter
moisture between flocks
In the U.S., most farmers are growing
on built-up litter that they keep for one
or two years. Moisture, along with
coccidia oocysts, builds up in that
litter and steps must be taken to dry
it out during the downtime between
flocks. Hess said drier litter can be
used longer more effectively.
Windrowing and composting
litter between flocks is being used
to reduce the pathogen load in the
built-up litter, but it may not be
removing the moisture effectively.
One method Hess said he's
hearing more about as farms transition to antibiotic-free growing is

tilling the litter. After windrowing
and composting the litter, growers
are spreading the litter back out in
the house and tilling it up to allow
moisture to escape. After doing this,
the heaters are turned on to get the
house hot; then fans are turned on
to blow that released moisture out of
the house entirely.
After two or three of these
cycles, the level of moisture is
significantly reduced. There is
expense associated with this
method, as it requires a tilling
machine and extra resources for
heat and ventilation, but it works to
drive down both the moisture and
the ammonia level in the litter.
One thing Hess cautioned
against is tilling without de-caking
the litter. Growers are using
de-caking devices to pull the caked
(or wet and clumped-up) litter, from
the built-up litter. While those who
are tilling without de-caking may
think they are saving time and
costs, they are actually chopping up
the caked litter into small chunks
without removing any moisture. ■
