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
