Which gas is the primary air quality concern in confined swine facilities?
Answer: Ammonia
Ammonia released from manure is the principal air quality and health hazard in swine confinement housing.
What is the function of a manure management lagoon?
Answer: Store and biologically treat livestock manure
An anaerobic lagoon stores and treats manure through biological decomposition before land application.
In broiler housing design, litter management is critical because poor litter quality leads to:
Answer: Paw and hock burns, respiratory disease, and reduced performance
Wet litter harbors pathogens, produces ammonia, and causes contact dermatitis (hock burn) in broilers.
A vapor barrier in a livestock building is installed to:
Answer: Prevent condensation and moisture damage to insulation and structural members
A vapor barrier on the warm side of insulation prevents warm, moist indoor air from condensing within the wall assembly.
The purpose of eave openings in a naturally ventilated barn is to:
Answer: Allow cool fresh air to enter at low velocity
Eave inlets allow fresh outside air to enter at the perimeter and flow up toward the ridge outlet.
Which type of concrete floor finish is recommended for dairy cow alleys to reduce slipping?
