Ammonia Emission Control for Animal Housing systems using Dry Manure
|
In livestock facilities, ammonia results primarily
from the breakdown of urea (present in urine) by the enzyme urease
(excreted in feces). In poultry, urease is excreted with uric
acid. Undigested feed protein and wasted feed are additional
sources of ammonia in animal productions systems. Strategies
to reduce ammonia from animal housing focus primarily on preventing
ammonia formation and volatilization, or downwind transmission
of ammonia after it is volatilized. Four practices used to control
ammonia emission from livestock housing are discussed below.
