Nipple drinker flow rates should be tested on a weekly basis during the growing cycle to ensure that water
supply is high enough to meet maximum demands for daily water intake. Nipple drinker flow rates can be
measured by pressing a measuring cylinder onto a nipple at the end of a nipple line to activate the flow of
water through the nipple for 1 minute. The amount of water in the measuring cylinder indicates the flow rate
through each nipple in the nipple line per minute. A higher than expected flow rate for age may increase
leakage and related wet litter problems. A lower than expected flow rate may not allow enough water for
all birds to drink and lead to problems with dehydration. Measuring the static flow rate of a nipple can help
to identify problems within drinking systems. Manufacturers recommendations should be followed for the
specific type of drinker being used.
