ABSTRACT:
This invention relates to a method of producing protein-rich forage or nitrogenous fertilizer as a commercial product from fowl droppings, swine dung, cow dung and the like by charging said ordure into a heated animal, fish or vegetable oil, subjecting the mixture to a smooth dehydrating treatment under the two-step reduced pressure conditions starting initial by with a limited pressure reduction and later increasing the degree of pressure reduction, and thereafter squeezing oil out of the treated mixture to thereby produce said forage or fertilizer. Said method is conducive to the prevention of malodor pollution caused by said livestock excrements and can also eliminate the wasteful use of fuel required in the incineration treatments.
