Attention to detail and preparedness make a big difference in how growers can protect their turkeys
from heat stress. Austin Alonzo

Protecting adult flocks
Tunnel ventilation: The best way to control heat
stress on older turkeys is using tunnel ventilation,
Puffenbarger said. However, there are plenty of
conventional turkey houses that will continue to be
used, so growers need to manage what they have and
use tools like fans and foggers to minimize heat stress.
That said, using a tunnel ventilated house is not
a surefire way to avoid heat stress. The fans must be
run and operated in accordance with the ambient
environmental conditions.
Water: In conventional and tunnel houses, access
to water is essential for the birds under heat stress. The
drinker lines must be operational and set to the correct
height. Moreover, they need to be supplied with the
appropriate amount of drinkers for the population of
the house. If birds need to work hard to get water, there
can be higher mortality and worse performance. Water
needs to be cool, fresh and sanitized.
Water lines should be flushed regularly to prevent

biofilm build up and keep water cool for the flock. If
there is a drip pipe extending from a water system, it
should not touch the ground as that is a route for pathogens into the house. Farmers can also add electrolytes
to the water supply during the hottest part of the day to
help increase hydration levels.
Controlled flock distribution: Growers generally
do not like migration fences because of the inconveniences they create. However, Puffenbarger said, they
are designed to maximize turkey comfort and performance by keeping birds evenly distributed through
the house so they have equal access to feed and water.
This can lead to greater performance.
Stocking density: Reducing stocking density
by 10% in the hottest months can help reduce heat
stress. Puffenbarger said growers may be opposed
to this but it will pay off in terms of growth rate and
lower mortality.
Hanging fans: Fans help move air around and
distribute heat in the house. They must be the right
