Poultry layer houses are mostly open house system that generally faced with flies and odour and has become nuisance factors to society and the environment. Commonly reported compounds associated with livestock waste include ammonia (a sharp pungent odour) and hydrogen sulfide (a rotten egg odour). Ammonia and hydrogen sulfide are pollutant gases related to chicken manure. High concentrations of ammonia inside animal houses represent potential health hazards to humans and animals (1). Hydrogen sulfide is considered the most dangerous gas when at acute concentration has been responsible for many animal as well as human deaths (2). The use of microorganisms called ?Effective or Beneficial Microorganisms? in poultry manure was claimed to be effective in preventing odour and flies and has no known adverse effects on plants, animals, humans, or environment after over a decade of application (3). Odour production cannot be completely prevented on a farm. Therefore, most odour control methods are designed to keep or dissipate odours within the farm boundary, thus minimizing odour complaints from surrounding neighbours. This paper reports the effect of applying effective microorganisms in controlling ammonia and hydrogen sulfide from poultry manure.
