Evaluation of Ammonia Emissions from Broiler Litter
Ammonia (NH3) emissions from poultry litter results in air pollution and can cause high levels of NH3 in poultry houses, which negatively impacts bird performance. The objectives of this study were to: (1) conduct a nitrogen (N) mass balance in broiler houses by measuring the N inputs (bedding, chicks, and feed) and N outputs (birds marketed, mortality, litter/cake, NH3 emissions, and nitrous o...
متن کاملOcular responses to ammonia in broiler chickens.
In two trials, 60 male commercial broilers were placed in each of eight environmentally controlled chambers receiving 0, 25, 50, or 75 ppm aerial ammonia from 1 to 28 days. Birds exposed to 25 ppm (lower concentration) ammonia gas developed ocular abnormalities but at a slower rate when compared with birds exposed to 50 and 75 ppm (higher concentrations). Birds exposed to higher concentrations ...
متن کاملBroiler litter ammonia emissions near sidewalls, feeders, and waterers.
Ammonia (NH3) volatilized from broiler litter diminishes indoor air quality, which can potentially decrease bird productivity. Emissions of NH3 exhausted from broiler houses pose environmental concerns for ecosystem biodiversity, aquatic nutrient enrichment, and particulate formation in the atmosphere. Research was conducted sampling litter (rice hull base) in 3 tunnel-ventilated commercial bro...
متن کاملIncubation Conditions and Broiler Performance
However, the 21 days that the chick spends in the incubator is significant proportion of its life; for a broiler killed at 40 days, 34 % of its total life span is spent in the egg. Recent research has shown that aspects of incubation and hatchery process control can have profound effects on broiler performance all the way up to slaughter weights. Often, small changes will generate significant i...
