Claim 12

The process for inhibiting the generation of ammonia and other noxious gases from animal excreta set forth in claim 9 in further combination with the step of: maintaining a bed of liquid slurry of the excreta in the pit having a pH rating of an acidity condition at all times, and scraping the pit periodically to remove excess excreta therefrom while maintaining at all times the pH rating of the excreta in the liquid slurry of the pit.

Claim 13

The process for inhibiting the generation of ammonia and other noxious gases from animal excreta set forth in claim 10 in further combination with the step of: adding ozone to the chemical additive prior to diluting the excreta for controlling bacteria in the excreta.

Claim 14

A process for inhibiting the generation of noxious gases from animal excreta through the control of the excreta under the animal in a feedlot comprising the steps of: collecting the manure underneath the animal in a feedlot, diluting the excreta with ozone to control bacteria growth in the excreta, and periodically removing a part of the excreta from underneath the animal while maintaining said control of the bacteria growth of the excreta.

Claim 15

A process for inhibiting the generation of noxious gases from animal excreta through the control of the excreta under the animal in a feedlot comprising the steps of: collecting the manure underneath the animal in a feedlot, diluting the excreta with ozone to control bacteria growth in the excreta, and periodically removing a part of the excreta from underneath the animal while maintaining said control of the bacteria growth of the excreta.

Claim 16

Apparatus for collecting and processing animal waste comprising: a pen for containing livestock having a slotted floor, a trough arranged below said floor for receiving animal waste dropped therein by the animals housed in said pen, means for diluting the animal waste with a chemical additive for controlling a pH rating of the waste, and means for periodically removing the animal waste from said trough while maintaining a liquid slurry at all times at the bottom of said trough.
