Abstract

The study was carried out in the 10 small, 6 medium and 4 large poultry farms of Mirsarai, Chittagong during 25 May to 05 July 2016. The objectives of the study were to identify the poultry waste materials and to know their utilization and disposal procedure. Pollutants in the poultry farm include litters, manures, odor, 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. Litter can be processed following deep stacking, composting and in lagoons, which were available in the study area.
