| Abstract | ||||
| Animal wastes represents a vast reservoir of cheap nutrients, particularly for ruminants. In most countries, waste, particularly from poultry, is easily collected, as it is and concentrated in small areas. Feed costs for dairy or beef cattle usually rep < /strong>resent 50-80% of the total production costs this can be reduced to 20-40% by utilizing animal and poultry wastes as supply source of protein, minerals and other nutrients. As the chemical composition and thus the nutritive value of wastes depend on many factors, of which waste management contributes major p < /strong>art, many different management techniques have been tried to ensure the safety of these wastes as feed. The results achieved in this study indicate that all methods used for processing the animal and poultry wastes cause marked reduct ion of the total viable count. The indicator bacteria is completly inhibited at the end of the 1st week of exposure to formalin and sunlight, but they remain viable till the end of the 2nd week of exposure to sodium hydroxide and slaked lime. | ||||
