milliliter. The limits for total
coliforms and fecal coliform
levels are 50 CFU/ml and 0 CFU/
ml, respectively. It is important
to measure the total bacteria
at the water source, and at the
entrance and exit of the poultry
house. CFU values should be
very similar in these three
points. If any contamination is
detected in the system, it should
be investigated. Penz suggested
the use of endoscopes to check
pipe cleanliness.
If the pipes are filled with dirt,
they must be cleaned. Samples
must always be taken before filtration, to know what gets to the

house and what kind of treatment
is needed. At least two chemical
and microbiological analyses
should be done per year.

Water temperature
After 20 C (68 F), for every 1 C
(1.8 F) of temperature increase,
water consumption increases
6% and feed consumption
decreases 1.2%, favoring wet
litter. For chicks, water must enter
the house colder than 25 C (77
F). It is important to emphasize
that chicks can't drink cold water,
however. If they feel the water
is a bit cold, they will wait until

water, it must be
known that hypochlorous acid (HClO) is
more efficient as a
bactericide than hypochlorite (OCI-).
Pool chlorine meters
should not be used
because it gives total
chlorine (hypochlorous
plus hypochlorite).
Devices that measure
redox are recommended since they
determine free
residual chlorine in
the water. Strips or
orthotolidine do not
distinguish between
OCI- and HClO.

reaches the ideal temperature of
consumption.
If the water is warm at the
source, work to find a way to cool
the water before it gets to the house.
Water tanks must be protected,
especially from the sun. With a
simple roof, cold water can stay
cold until consumption. Pipes must
also be protected. Do not place
them just under the roof. It's the
hottest place in the house; just a few
meters worth of exposure can raise
the temperature to a point where
chickens reduce consumption. ■
