MANAGING POULTRY WATER SYSTEMS
Chlorine is available in several
forms: liquid, gas and chlorine dioxide. The chemical must be used
carefully, and gas and chlorine
dioxide require special handling.
Those using liquid chlorine should
know the chemical can damage rubber components of water systems
and that bacteria can grow resistant.
Liquid chlorine is effective, and kills
the most bacteria, when the water's
pH value is 7 or less. Foy recommended using an alternative product
for two flocks if the liquid chlorine
product stops working as well as it
did in the past.
Several different percentages of
hydrogen peroxide, ranging from 20
percent to 50 percent solutions, are
on the market. Different mixtures re-

quire different usage methods. Some
hydrogen peroxide products include
additives that increase the active stability of hydrogen peroxide.
Use daily water treatment under
certain circumstances: Foy recommended daily water treatments during the following times:
■ The first two weeks of a flock:
Warm, slow-moving water that's
continuously re-inoculated needs to
be treated. Foy said bacteria is present in the highest amounts during
this period, and it's one of the most
critical times for treatment.
■ After adding supplements:
KEEPING A CLEAN WATER supply
requires a two-step program
focused on regular cleansing and
Clean after adding supplements, including acids, in the
■ After using vaccines: Treat
daily for a week after injecting a
vaccine through the water line.
Additionally, daily treatment
should occur whenever probiotics
or vaccines are not being injected
into the water line.
Don't rely on filters, water softeners, reverse osmosis or ultraviolet
light: Foy cautioned against relying
on these devices to clean water.
Filters help, but they do not remove
all the bacteria in a water line. Water
softeners, she said, are not useful for
disinfecting water. Reverse osmosis
and UV light must be used as part
of a water treatment program. They
clean the incoming water, but there
is no residual effect as the water
goes into the barn. ■
