Over the past decades, the poultry sector’s growth and trends towards intensification and concentration have given rise to a number of environmental concerns. A direct consequence of these structural changes (industrialization, geographical concentration and intensification) in poultry production is that far more waste than can be managed by land disposal is produced, resulting in environmental...

Although poultry provides an economically sound alternative protein source worldwide, negative environmental effects attributable to poultry production in Egypt have not been addressed. The environmental hazard arising from excess nitrogen and phosphorus in poultry waste as well as other contaminants such as drug residues, pathogenic organisms, and viruses (like avian influenza) could be elimin...

The effect of poultry waste application on physicochemical and biological properties of sandy clay loam soil was investigated on a 7m X 7m plot of land. Plot was divided into four portions and 7.5kg each of broiler, cockerel and layers waste was applied to plot A, B, and C in slurry form while plot D was used as control(no application) for eight weeks with two weeks interval. After the fourth a...

Differences in the properties of organic phosphorus (P) sources, particularly those that undergo treatment to reduce soluble P, can affect soil P solubility and P transport in surface runoff. This 2-yr field study investigated soil P solubility and runoff P losses from two agricultural soils in the Mid-Atlantic region after land application of biosolids derived from different waste water treatm...

Poultry industry wastes, namely feathers and poultry litter, are an interesting source of substrate for biogas production. The aim of this work was to assess the biomethane potential of raw poultry wastes, as well as the possibility of enhancing this potential by favouring the hydrolysis of cellulolytic and proteinaceous material in the wastes by using bioaugmentation and thermochemical pre-tre...

The investigation to determine the different litter/manure management practices of poultry farmers was carried out in Port Harcourt urban area. A well structured questionnaire was administered to 30 randomly selected poultry farmers in the study area by one on one interview and observation of the environment. The results revealed that poultry farming is on the increase. Majority of these farmer...

Feathers are byproduct waste of poultry processing plant and produced in large amount. A small percentage of feather waste is steamed, chemically treated, ground, to form feather meal a dietary protein supplement for animals. Alternatively, keratin can be biodegraded by some Keratinolytic bacteria and in this study Keratinase producing bacteria and their Keratinolytic enzyme production was inve...
