WASTE MANAGEMENT OF COMMERCIAL POULTRY FARMS IN BANGLADESH (Pages : 34 - 37)

Poultry farm provides meat, egg and employment for the people of Bangladesh and in the same time it also generates large quantities of waste materials. A survey was carried out in the 10 small, 6 medium and 4 large farms of Kishoregonj, Mymensingh and Gazipur districts during November 2003 to April 2004 to identify the poultry waste materials and to know their disposal procedure in Bangladesh. Pollutants in the poultry farm include litters, manures, odors, noise, feathers, dust and chemicals, wastewater, insects, dead birds, hatchery debris and dust from feed manufacturing plants. Litter is generally a mixture of manure, bedding materials, wasted feed, feathers and some portion of soil. Among the small farm owners 20% farmers could not use their poultry litter for any particular work, 40% of them sold their poultry litter in the market, 30% of them used their poultry litter for crop production and, 10% of them used their poultry litter for fish culture. About 50% of the medium farm owners used their litter for fish culture and all the large farm owners sold their litter after a particular time. It was observed that litter contained a high amount of nitrogenous substances (crude protein 24.9%) and ash 24.7% and total digestive nutrients 50%. Litter can be processed following deep stacking, composting and in lagoons, which were available in the study area.Download
