Atmospheric ammonia is detrimental to the performance of modern commercial broilers

Atmospheric Ammonia Is Detrimental to the Performance of Modern Commercial Broilers.jpg
Atmospheric ammonia inhibits broiler performance. Quantified effects are based on older genetic stock with a BW of 2,000 g at 7 wk. In contrast, modern genetic stock reaches 3,200 g at 7 wk of age. To assess the impact on present day broilers, 2 trials were conducted exposing male broilers to graded levels (0, 25, 50, and 75 ppm) of aerial ammonia…

Application of an electrostatic space charge system for dust, ammonia, and pathogen reduction in a broiler breeder house

Application of an electrostatic space charge system for dust, ammonia, and pathogen reduction in a broiler breeder house.jpg
Airborne dust in poultry housing is known to be one of the primary means by which disease-causing organisms are spread throughout a house. An electrostatic space charge system (ESCS) was used to reduce airborne dust in a small-scale broiler breeder house. The system used ceiling fans to distribute negatively charged air throughout the room and to…
