Abstract
Abstract Poultry feces are processed through a digester and a separator to produce undissolved solid material and a liquid filtrate. The solid material contains primarily food undigested by the poultry which is blended with comminuted egg shells, comminuted feathers, nutrients to provide a balanced food and new food to produce feed for fowl or stock. The filtrate is chemically treated for recovery of uric acid precipitate, and the remaining filtrate is used as a bacterial culture to produce bacterial protein. Used liquid from the bacterial culture is used as hydroponic culture to grow green fodder.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
21 words
The method defined in claim 1, wherein bacterial culture is grown in the remaining body of liquid thereby producing bacterial protein.
Claim 2
Dependent Claim
17 words
The method defined in claim 1, wHerein green fodder is grown in the remaining body of liquid.
Claim 3
Dependent Claim
40 words
The method defined in claim 1, wherein the digesting mixture includes a base solution and comminuted poultry feces for dissolving soluble components from the feces, and further treating the separated body of liquid with reagents for recovering therefrom uric acid.
Claim 4
Independent Claim
68 words
The method of treating poultry feces which comprises digesting a mixture of a base solution and comminuted poultry feces for dissolving soluble components from the feces, separating the solid phase and the liquid phase of the digested mixture, and treating such liquid phase with reagents for recovering therefrom precipitated uric acid, the liquid remaining after precipitation of the uric acid being adapted for use as a culture medium.
Claim 5
Dependent Claim
29 words
The method defined in claim 5, including the further step of growing bacterial culture in the liquid remaining after precipitation of the uric acid and thereby producing bacterial protein.
Claim 6
Dependent Claim
25 words
The method defined in claim 5, including the further step of hydroponically growing green fodder in the liquid remaining after precipitation of the uric acid.
