Microprocessor control and numerical model for broiler house summer ventilation utilizing a rockbed heat sinkChen, Chaur-Fong 13 June 1988 (has links)
Summer brooding often requires some form of air modification in
addition to maximizing ventilation rate to prevent animal heat stress
and possible death due to hyperthermia. A rockbed thermal storage
module was designed and constructed to provide sensibly cooled air
for a broiler space under summer brooding conditions. A mathematical
model of rockbed thermal storage module was developed to predict
performance of the prototype module. Experiments to evaluate the
rockbed module under different weather conditions and operating
schedules were conducted. The results were presented and compared
with the mathematical simulation.
A microprocessor control system was designed and assembled to
control the ventilation air that would enter a broiler house during
warm weather periods. The system was capable of taking temperature
samples from thermocouples and then operate a damper arrangement
which determined the mixture of outdoor and sensibly cooled air from
rockbed thermal storage module. The cost and feasibility of
utilizing a rockbed thermal storage module and a microprocessor
control ventilation system were discussed. / Graduation date: 1989

Comparison on the effectiveness of different chemical treatments of built-up broiler litter on broiler house environment and broiler performanceUddin, Zaheer 14 March 1991 (has links)
The objectives in these four experiments were to observe
the effectiveness of sodium bisulfate and clinoptilolite and
different methods of application of sodium bisulfate, ferrous
sulfate heptahydrate and Micro Aide® on atmospheric ammonia
level in the broiler house and on broiler performance.
The first experiment was conducted to determine the
optimum effective level of the litter application of sodium
bisulfate. Atmospheric ammonia at 4 weeks and litter moisture
at 3 weeks
treated-pens
were significantly lower in sodium bisulfate
(488 g/m²) than in the untreated control pens.
However, broiler performance was not significantly affected
with any treatment. Litter application of sodium bisulfate at
244 g/m² and 488 g/m² were comparable and better than the 122
g/m² and untreated control.
In Experiments 2 and 3 comparisons of litter chemical
treatments of liquid Micro Aid® (8.75 ml/L H₂O) applied at 0,
2, 4,and 6 weeks; granular Micro Aid® (0.5 mg/g of feed) fed
continuously throughout the experiment, and litter application
of ferrous sulfate (732 g/m²); clinoptilolite (2443 g/m²),
sodium bisulfate (244 g/m²) and ferrous sulfate (732 g/m²) were
made for 7 week periods. Ferrous sulfate-treated pens (732
g/m²) had significantly lower litter pH at 2, 4 and 6 weeks
than untreated control and significantly lower atmospheric
ammonia levels at 3 and 6 weeks than the clinoptilolite (2443
g/m²), sodium bisulfate (244 g/m²) and untreated control in the
other experiment.
In the fourth experiment, sodium bisulfate was applied
twice (244 g/m²/application) at 0 and 4 weeks, sodium
bisulfate applied once (488 g/m²) and ferrous sulfate applied
once (732 g/m²) prior to the experiment. At 4 weeks mean body
weights and feed conversion were significantly better with one
sodium bisulfate application than the untreated control. At
7 weeks feed conversion (P<0.08) and male body weights (P<0.1)
were slightly better in one sodium bisulfate application than
in the untreated control while mortality was significantly
lower in the untreated control pens. Most mortality occurred
after 4 weeks and were due primarily to Sudden Death Syndrome.
Atmospheric ammonia levels at 0, 1, 2, 3 and 4, weeks and
litter pH levels at 0, 1, 2, 3, and 4 weeks were significantly
lower in pens with one application of sodium bisulfate than in
pens untreated. Litter application of sodium bisulfate once
(488 g/m²) seemed to be the best litter treatment in reducing
atmospheric ammonia. / Graduation date: 1991
