Sludge as an animal feed. Table 2 reveals that the highest protein content of the sludge
generated from flotation was 8.88% while the lowest one was 7.5%and it gave a mean value of 8.26%.
Similarly , the richest phosphorus level of the sludge generated from flotation was 0.12%while the
poorest one was 0.1% and it gave a mean value of 0.11% . For the calorific value , the highest energy
value of the sludge generated from flotation was 6840 cal /g while the lowest one was 6580 cal / g and it
gave a mean value of 6690 cal/g.
Vegetable , fruit , corn,food wastes are used for the rearing of poultry and swine in the past.
The calorific value of various animal feeds and food wastes selected for comparison with that of the
sludge from flotation of this study attempts to be utilized as energy for animal growth and
metabolism.
