A process of treating animal wastes, which is characterized in: (a) contacting heated animal oil, fish oil or vegetable oil with the animal wastes in an enclosed container; (b) reducing pressure in the enclosed container, and at the reduced pressure condition agitating the animal wastes using the heated animal oil, fish oil or vegetable oil as the heat-conduction medium; (c) during the initial pressure-reduction process, maintaining the reduced pressure condition at 100 mm Hg ~ 300 mm Hg below normal pressure; (d) during the middle pressure-reduction process, maintaining the reduced pressure condition at 500 mm Hg ~ 700 mm Hg below normal pressure; (e) during the final pressure-reduction process, maintaining the reduced pressure condition at 700 mm Hg ~ 750 mm Hg below normal pressure.
