Ammonia (NH3) Emissions in Laying Hen Farms: Distribution and Influencing Factors in Sidrap, Indonesia

Abstract

This review is devoted to methodology that can help to assess emission of gases from poultry housings and could be used to expand the knowledge base of researchers, policymakers and farmers to maintain sustainable environment conditions for farming systems.Concentration and emission of ammonia, methane, nitrous oxide and carbon dioxide in poultry barns are discussed in this paper.Surveys of ammonia and greenhouse gases mean concentrations and emission factors in different poultry systems are showed.This paper is also gives the findings in emission mitigation, especially to different manure handling practices, management schemes, housing and facility designs for broilers and laying hens.Finally this paper focused on investigating practical means to reduce air emissions from animal production facilities.
