Abstract
Abstract A compound animal feed suitable for long-term preservation is disclosed. The feed is constituted by a mixture including a product chosen from wet cereals such as wet maize grain, maize grain meal or mash, maize cob meal or mash or their mixtures, which product is ground to a degree of fineness suitable for direct feeding to animals; molasses suitable for use in animal husbandry; and oil or fat suitable for use in animal husbandry, the feed mixture having a pH value less than 4. Preferably this pH value is obtained by treatment of the fine ground product with phosphoric acid. Also disclosed is a process for the long-term preservation of wet cereals by treatment thereof with phosphoric acid or other suitable acids until a pH less than 4 is reached, and then combining the treated cereals with molasses and oil or fat.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A compound animal feed having a resistance to deterioration that makes the feed suitable for long-term preservation, consisting essentially of uncooked, ground cereals having a naturally occurring moisture content of 30-40% by weight, said cereals being characterized by an absence of fermentation treatment; at least one acid present in an amount sufficient to provide the feed with a pH of less than 4; a fat or oil in an aount of 10-15% by weight based upon the weight of the wet cereals; and molasses in an amount of 8-18% by weight based upon the weight of the wet cereals.
Claim 2
Dependent Claim
99 words
A compound animal feed having a resistance to deterioration that makes the feed suitable for long-term preservation, consisting essentially of uncooked, ground cereals having a naturally occurring moisture content of 30-40% by weight, said cereals being characterized by an absence of fermentation treatment; at least one acid present in an amount sufficient to provide the feed with a pH of less than 4; a fat or oil in an aount of 10-15% by weight based upon the weight of the wet cereals; and molasses in an amount of 8-18% by weight based upon the weight of the wet cereals.
Claim 3
Dependent Claim
47 words
The compound animal feed of claim 1, wherein the at least one acid consists essentially of phosphoric acid in an amount of 2-4% by weight based upon the weight of the wet cereals and the pH of the feed is in the range of 2 to 3.
Claim 4
Dependent Claim
32 words
The compound animal feed of claim 2, wherein a portion of the phosphoric acid is replaced by an acid selected from the group consisting of hydrochloric, formic, propionic, citric and fumaric acids.
Claim 5
Dependent Claim
100 words
A process for the long-term preservation of fresh, uncooked cereals having a naturally occurring moisture content of 30-40% by weight, comprising: wetting the cereals with an aqueous solution containing phosphoric acid in an amount of 2-4% by weight based upon the weight of the cereals; and mixing the acid-treated cereals with a fat or oil in an amount of 10-15% by weight based upon the weight of the cereals and molasses in an amount of 8-18% by weight based upon the weight of the cereals, said process being characterized by an absence of cooking or fermentation treatment of the cereals.
Claim 6
Dependent Claim
100 words
A process for the long-term preservation of fresh, uncooked cereals having a naturally occurring moisture content of 30-40% by weight, comprising: wetting the cereals with an aqueous solution containing phosphoric acid in an amount of 2-4% by weight based upon the weight of the cereals; and mixing the acid-treated cereals with a fat or oil in an amount of 10-15% by weight based upon the weight of the cereals and molasses in an amount of 8-18% by weight based upon the weight of the cereals, said process being characterized by an absence of cooking or fermentation treatment of the cereals.
Claim 7
Dependent Claim
34 words
The process of claim 4, wherein an acid selected from the group consisting of hydrochloric, formic, propionic, citric and fumaric acids is substituted for a portion of the phosphoric acid in the aqueous solution.
Claim 8
Dependent Claim
122 words
A process for preparing a compound animal feed consisting essentially of uncooked, fresh cereals having a naturally of occurring moisture content of 30-40% by weight, said feed being characterized by a resistance to deterioration that makes the feed suitable for long-term preservation, comprising: wetting the cereals with an aqueous solution containing phosphoric acid in an amount of 2-4% by weight based upon the weight of the cereals; and mixing the acid-treated cereal with a fat or oil in an amount of 10-15% by weight based upon the weight of the cereals and molasses in an amount of 8-18% by weight based upon the weight of the cereals, said process being characterized by an absence of cooking or fermentation treatment of the cereals.
Claim 9
Dependent Claim
122 words
A process for preparing a compound animal feed consisting essentially of uncooked, fresh cereals having a naturally of occurring moisture content of 30-40% by weight, said feed being characterized by a resistance to deterioration that makes the feed suitable for long-term preservation, comprising: wetting the cereals with an aqueous solution containing phosphoric acid in an amount of 2-4% by weight based upon the weight of the cereals; and mixing the acid-treated cereal with a fat or oil in an amount of 10-15% by weight based upon the weight of the cereals and molasses in an amount of 8-18% by weight based upon the weight of the cereals, said process being characterized by an absence of cooking or fermentation treatment of the cereals.
Claim 10
Dependent Claim
34 words
The process of claim 6, wherein an acid selected from the group consisting of hydrochloric, formic, propionic, citric and fumaric acids is substituted for a portion of the phosphoric acid in the aqueous solution.
