Even when the average temper
ature in a livestock production
house is “on target,” regions with
in the building may be far above or
below desired temperature.

Research at Penn State investi
gates why temperature and other
air quality factors ate not uniform
within laying hen production
houses.
Depending on the building
design and the environmental con
trol system, air flow, airborne par
ticles, and temperature that one
group of birds experiences can be
greatly different than that exper
ienced by birds in a different reg
ion of the house.
Environmental conditions
affect production, feed intake,
behavior, and health. Nonunifor
mity of environmental conditions
prevents the entire flock from pro
ducing to its genetic potential and
therefore reduces the farm’s jirofii
potential.
In an effort to understand more
about temperature uniformity it
laying hen production buildings.:
case study was conducted. Th
production buildings on the sam
farm complex with similar bir
densities, bird ages, and environ
mental control management wei
monitored hourly from May 199
until February 1994. Each hous
contained 48 temperature sensor
The Turbo Positive™ hous
(Figure 1) is a positive pressui
system with slotted ceiling ini*,
and fens in the attic space, and is 21
meters x 206 meters (70 feet x 675
Jet). The Turbo Negative™ house
(Figure 2) is a negative pressure
system with slotted ceiling inlets
and fens in the pit, and is also 21
meters x 206 meters (70 feet x 675
foet). The perimeter baffle house
(Figure 3) is a negative pressure

Ventilation rates are basically
dependent upon target inside
temperature, bird density, and out
side air temperature. In the case
study, 11 outside temperature
ranges were investigated from less
than -10 C. (14 F.) to greater than
35 C. (95 F.). Temperature ranges
were in increments of 5 C. between
-10 C. and 35 C. (-10 to -5, -5 to

deviation of temperature withij
the building for each outside temp
erature range was calculated.
During cold weather, the great
est stratification of temperatur
occurs in buildings because les
ventilation is needed. This is evi
dent in Figure 4 which shows th
standard deviation of tcmperatui
in each building for each outsid
temperature range.
