(E) processing the soiled litter on-site at the poultry farm by compressing the soiled litter and heating the soiled litter to at least a predetermined temperature;
(F) placing the processed litter on the floor of at least one poultry house on the poultry farm at a time when the processed litter is still warmer than the at least one poultry house; and
(G) introducing at least a second plurality of birds into the at least one poultry house no later than two days after the processed litter has been placed therein and thereafter raising the second plurality of birds in the at least one poultry house.
2. The method of doing business of claim 1 wherein step (E) comprises the step of running the soiled litter through a screw-type extruder.
3. The method of doing business of claim 1 wherein the predetermined temperature is sufficient to kill bacteria and insects in the animal waste.
4. The method of doing business of claim 1 wherein the predetermined temperature is 132\xb0 C.
5. The method of doing business of claim 1 wherein the predetermined temperature is 145\xb0 C.
6. The method of doing business of claim 1 wherein the predetermined temperature is 160\xb0 C.
7. A method for poultry farm to do business comprising the steps of:
(A) placing clean litter on the floor of a poultry house;
(B) raising a first plurality of birds in the poultry house, during which the birds defecate on the litter, thereby soiling the litter;
(C) removing the first plurality of birds from the poultry house;
(D) removing substantially all of the soiled litter from the poultry house;
(E) processing the soiled litter by heating the soiled litter to at least a predetermined temperature;
(F) placing the processed litter on the floor of at least one poultry house; and
(G) introducing at least a second plurality of birds in the at least one poultry house no later than two days after the processed litter has been placed therein and thereafter raising the second plurality of birds in the at least one poultry house.
8. The method of doing business of claim 7 wherein the step of processing the soiled litter further comprises the step of compressing the soiled litter.
9. The method of doing business of claim 8 wherein step (F) comprises the step of running the soiled litter through a screw-type extruder.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
