Abstract

Abstract Feed grain compositions are prepared from grain and feedlot wastes by fermentation procedures which are carried out in simple equipment suitable for use on the feedlot site. The procedures are also suitable for industrial scale operations. Fecal odor of the waste is quickly eliminated and replaced by one that resembles the odor of silage. The fermented product has significantly more crude protein than corn, and it is palatable to livestock.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 86 words
A method of preparing animal feed grain compositions comprising the steps of: a. mixing from 2 to 15 parts dry weight basis (dwb) of animal feedlot waste (FLW) with 100 parts dwb of fragmented grain (FG) and an amount of water such that the resulting mixture contains from 35% to 45% moisture; and b. aerobically fermenting the mixture resulting from step (a) while submitting said mixture to a tumbling action for a time sufficient to obtain a pH in the mixture of from 4 to 5.
Claim 2
Independent Claim 86 words
A method of preparing animal feed grain compositions comprising the steps of: a. mixing from 2 to 15 parts dry weight basis (dwb) of animal feedlot waste (FLW) with 100 parts dwb of fragmented grain (FG) and an amount of water such that the resulting mixture contains from 35% to 45% moisture; and b. aerobically fermenting the mixture resulting from step (a) while submitting said mixture to a tumbling action for a time sufficient to obtain a pH in the mixture of from 4 to 5.
Claim 3
Dependent Claim 16 words
A method as described in claim 1 wherein the fragmented grain is corn, wheat, or milo.
Claim 4
Dependent Claim 25 words
A method as described in claim 1 wherein the water is present in amounts such that the resulting mixture contains from 38% to 42% moisture.
Claim 5
Dependent Claim 19 words
A method as described in claim 1 wherein the pH recited in step (b) is from 4 to 4.5.
Claim 6
Dependent Claim 18 words
An animal feed grain composition consisting essentially of the fermented product produced by the method of claim 1.
Claim 7
Independent Claim 132 words
A method of preparing animal feed grain compositions comprising the steps of: a. diluting animal feedlot wastes (FLW) with water in amounts and in a manner sufficient to produce an essentially homogenous slurry containing from 3% to 20% solids; b. removing an amount of solids from said slurry such that the remaining liquid portion (FLWL) contains from 2% to 15% FLW solids; c. mixing the FLWL with fragmented grain (FG) in amounts such that the mixture contains from 2 to 15 parts dry weight basis (dwb) FLWL and 100 parts dwb FG and from 35% and 45% moisture; and d. aerobically fermenting the mixture resulting from step (c) while submitting said mixture to a tumbling action for a time sufficient to obtain a pH in the mixture of from 4 to 5.
Claim 8
Independent Claim 132 words
A method of preparing animal feed grain compositions comprising the steps of: a. diluting animal feedlot wastes (FLW) with water in amounts and in a manner sufficient to produce an essentially homogenous slurry containing from 3% to 20% solids; b. removing an amount of solids from said slurry such that the remaining liquid portion (FLWL) contains from 2% to 15% FLW solids; c. mixing the FLWL with fragmented grain (FG) in amounts such that the mixture contains from 2 to 15 parts dry weight basis (dwb) FLWL and 100 parts dwb FG and from 35% and 45% moisture; and d. aerobically fermenting the mixture resulting from step (c) while submitting said mixture to a tumbling action for a time sufficient to obtain a pH in the mixture of from 4 to 5.
Claim 9
Dependent Claim 16 words
A method as described in claim 6 wherein the fragmented grain is corn, wheat, or milo.
Claim 10
Dependent Claim 20 words
A method as described in claim 6 wherein the mixture resulting from step (c) contains from 38% to 42% moisture.
Claim 11
Dependent Claim 19 words
A method as described in claim 6 wherein the pH recited in step (d) is from 4 to 4.5.
Claim 12
Dependent Claim 18 words
An animal feed grain composition consisting essentially of the fermented product produced by the method of claim 6.
