BIOFILM IN POULTRY DRINKING WATER

Dosing guidelines for acidifiers
To determine the proper application rate of
a water acidifier, water titration is used to
measure buffer capacity and establish a target
pH. Titration analysis should be performed on
the specific water supplied to the birds and can
be performed by a laboratory or done on-farm
using specially designed tools.

plant- and animal-derived proteins, organic acids can help
assure less undigested protein reaches the hindgut, potentially reducing the threat of dysbacteriosis.
The goal of using water acidifiers is to achieve a
pH of approximately 3.8 to 4.0. Water can be classified according to its alkalinity, or buffer capacity - a
measurement of water's capability to neutralize acids.
Knowing the water's buffer capacity helps determine
the best blend (level of buffering) and the recommended
application rate.
In water with high buffer capacity (high alkalinity),
a higher inclusion rate of acidifiers is required to reach
this target pH. Less-buffered acidifiers can help reach the
target pH at lower doses. A blend of organic acids may be
worth considering when the objective is to combat biofilm
and improve animal digestion, gastrointestinal microbial
balance or animal performance.
Dosage is especially important. Higher amounts of
a water acidifier will make more of the acid molecules
available to the animal to support desired effects. A
poultry nutritionist can advise on optimal dosing.

Flushing to dislodge
biofilm and buildup

Clean drinking water begins with flushing.
The system should be flushed with clean water
between bird cycles and after any treatment, such as
vaccines, antibiotics or vitamins delivered through water.
As disease risk is highest during a bird's first week, it is
advisable to flush systems at least twice during the first

For example, Trouw Nutrition's farm experts
use a tool that includes a photometer and
application rate calculator to help recommend
a specific inclusion rate for drinking water acidifier based on the water's alkalinity. This test
translates into the water acidifier dosage that
can be used to reach the desired pH.

week of production.
Flushing with clean water loosens substances that can
contribute to biofilm and washes away buildups that can
clog equipment. High pressure of 2 to 3 bars/units should
be applied during the flushing process.

Hydrogen peroxide
to disinfect between cycles

A simple and effective disinfectant between
cycles, hydrogen peroxide works very well in
killing many bacteria and removing biofilm buildup. It
also helps prevent biofilm from accumulating.
Applying the proper concentration of hydrogen
peroxide and allowing adequate treatment time is important to achieve desired disinfection results.
