Remodel swine
UNIVERSITY PARK - The
decade of the 1960’s will see many
of the swine buildings built in the
1970’5, especially farrowing and
nursery units, remodeled to reduce
environmental stress, which is an
important key to profitable pig
performance, says Daniel J.
Meyer.
Meyer, a Penn State Extension
Agricultural Engineer, says
ventilation problems in farrowing
and nursery units include short
circuiting, poor air distribution,
drafts due to excessive air speeds
(1/4 fps) and improper air inlet
adjustments, excessive air flows in
winter (high fuel costs), lack of
adequate summer air flows, and
high NH3 levels in winter in
buildings with over 10 days
manure storage.
Corrections for ventilation
problems include usins smaller
rooms for better air distribution,
using preheated air from service
alleys to reduce drafts, elminating
high speed air recirculation
systems (advertise no
stratification of air temperatures),
and using heat exchangers to
reduce fuel costs (single or
multiple room types). _

Meyer also cites pen or under
floor slotted PVC pipes connected
to fans where shallow or deep pits
are used, increasing fan capacity
in summer and/or more snout
cooling and using front creeps
where possible.
Manure system problems in
farrowing and nursery units are
getting manure away from the pigs
and out of the buildings more
frequently (10 days is maximum
before gases develop). Corrections
being utilized Meyer says include
going to more open-type flooring
materials, such as woven wire, and
using narrower gutter widths so
gutters fill faster and can be
drained by gravity sooner.
Naturally ventilated growing
and finishing buildings’ air quality
can best be improved in winter,
spring and fall by using adjustable
ridge openings of 6-24”, depending
on building roof type and pit
location, insulating the buildings
and using automatic door controls
on the ridge openings to hold
temperature more constant,
Meyer adds. In summer, less heat
stress can be achieved by using
sprinkler systems, large 60”
horizontal-type circulating fans (1
tor a
per 1000 sq. ft.), opening up the
sidewalls (1 ft. per 10 ft. of
building) and opening up the ridge.
