Upward vs. downward ventilation air flow in a swine house.
Posted in: Environment by admin on | No Comments
Several ventilation system designs are in common use, and very little is known about their relative performance in achieving an acceptable livestock building air quality. A ventilation system may be characterized quantitatively from the efficiency of the air exchange process and the effectiveness of the contaminant removal process. The theoretical framework is summarized and applied in an intervention study of upward vs. downward air flow in a pig house. The contaminants considered were NH3, CO2, dust, and excessive heat. It was concluded that the air exchange efficiency of upward air flow was superior to downward air flow. For some contaminants (CO2, excessive heat, dust) the ventilation effectiveness of upward air flow was superior to downward air flow.
Herbage Production and Nitrogen Recovery from Slury Injection and Fertilizer Nitrogen Application

The yield obtained with mid-season manure injection can be compared to the one obtained using fertilizer-N and the variability in the yields is also comparable. More variable results are obtained with broadcast spreading for the same application rates.
Electrostatic precipitation dust removal system for swine housing.
Posted in: Environment by admin on | No Comments
An electrostatic precipitation dust removal method for livestock housing was evaluated. Prototype testing was conducted in 2 animal rooms with similar ventilation, temperature control and management. Particle count and mass samples were collected. A 57-66% reduction of all dust particles was achieved.
