This report describes the measurement methodologies and results of gaseous and particulate matter (PM) emissions (ammonia, carbon dioxide, hydrogen sulfide, non-methane hydrocarbon or NMHC, total suspended particulate or TSP, PM10, and PM2.5) from two typical Tyson broiler production houses located on two separate farm sites in western Kentucky. Each broiler house was 43 ft x 510 ft (13 m x 155 m), with an initial, nominal placement of 25,800 (winter) to 24,400 (summer) Cobb-Cobb straight-run broilers per flock. The broilers were grown on new or built-up litter to an average age of 52 d (50 - 54 d), with flock downtime (i.e., empty house) ranging from 9 to 41 d.
