Concentrations and Settling Rates of Particulate Matter in Laying Hen Barns in the Hot Climatic Region of Cameroon CIGR Journal
Ngwabie, Ngwa Martin.
Particulate matter (PM) serves as a carrier of adhesive gaseous compounds, and may result to an underestimation of gas emissions from livestock barns when only filtered air samples are analysed. PM concentrations have hardly been studied in the unique livestock production system of Sub-Saharan Africa. This study was aimed at generating baseline data for PM (total suspended particulates) concentrations and settling rates in laying hen barns with cemented floors and wood shavings added as an initial bedding material. Measurements were conducted in two naturally ventilated laying hen barns in Cameroon; a barn with 4 months old hens that had just stated laying eggs and a barn with 18 months old egg laying hens. PM concentration was determined gravimetrically...
