Abstract

Abstract The invention is a sugar solution-based, preferably molasses-based, animal feed supplement which is produced as a viscous liquid that is gelled into a hard solid by the addition of a soluble calcium salt or oxide, preferably calcium oxide, a soluble phosphate, and a substantial quantity of magnesium oxide. Prior to its solidification a limited amount of discrete cellulose fibers can also be added to reinforce the solid and prevent its cracking. The solid product is hard and water resistant and has a limited consumption rate.

Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 135 words
The method of preparing an animal feed supplement from an aqueous sugar solution which consists essentially of the steps of adding a calcium reactant selected from the class consisting of calcium hydroxide and calcium oxide and soluble phosphate reactant selected from the class consisting of ammonium and alkali metal phosphates and phosphoric acid to said solution, each in an amount from 1.0 to 5.0 weight percent, sufficient to cause gelation of said sugar solution, agitating the resultant mixture to disperse the aforesaid reactants, and admixing into the sugar solution, subsequent to the addition of said calcium and phosphate reactants but prior to gelation of the solution into a solid, from 2 about 15 weight percent magnesium oxide, in an amount adequate to increase the hardness of the resultant solid product sufficiently to inhibit its consumption.
Claim 2
Independent Claim 135 words
The method of preparing an animal feed supplement from an aqueous sugar solution which consists essentially of the steps of adding a calcium reactant selected from the class consisting of calcium hydroxide and calcium oxide and soluble phosphate reactant selected from the class consisting of ammonium and alkali metal phosphates and phosphoric acid to said solution, each in an amount from 1.0 to 5.0 weight percent, sufficient to cause gelation of said sugar solution, agitating the resultant mixture to disperse the aforesaid reactants, and admixing into the sugar solution, subsequent to the addition of said calcium and phosphate reactants but prior to gelation of the solution into a solid, from 2 about 15 weight percent magnesium oxide, in an amount adequate to increase the hardness of the resultant solid product sufficiently to inhibit its consumption.
Claim 3
Dependent Claim 19 words
The method of claim 1 wherein said sugar solution is molasses of a concentration from 60 to 85 Brix.
Claim 4
Dependent Claim 24 words
The method of claim 1 wherein said magnesium oxide is finely subdivided with at least 90 weight percent thereof passing a 100 mesh screen.
Claim 5
Dependent Claim 15 words
The method of claim 1 wherein said magnesium oxide all passes a 225 mesh screen.
Claim 6
Dependent Claim 22 words
The method of claim 1 wherein said magnesium oxide is added at a concentration of from 4 to about 10 weight percent.
Claim 7
Dependent Claim 44 words
The method of claim 1 wherein discrete pulped cellulose fibers having lengths from about 1/16 to about 1 inch, are added to said sugar solution prior to its gelation in sufficient quantities to reinforce said solid products and inhibit the formation of cracks therein.
Claim 8
Dependent Claim 12 words
The method of claim 6 wherein said cellulose fibers are wood pulp.
Claim 9
Dependent Claim 14 words
The method of claim 7 wherein said wood pulp is unbleached kraft process pulp.
Claim 10
Dependent Claim 22 words
The method of claim 1 which includes adding from 2 to about 30 weight percent fat to said solution before it solidifies.
Claim 11
Dependent Claim 13 words
The method of claim 1 wherein calcium hydroxide is added to said solution.
Claim 12
Dependent Claim 13 words
The method of claim 1 wherein calcium oxide is added to said solution.
Claim 13
Dependent Claim 20 words
The method of claim 1 wherein phosphoric acid is added to said solution after the addition of said calcium reactant.
Claim 14
Dependent Claim 37 words
The method of claim 11 wherein calcium oxide is added to the solution and permitted to hydrate and phosphoric acid is thereafter added when the pH value of the solution has risen by 4 to 5 units.
Claim 15
Dependent Claim 32 words
The method of claim 1 including the addition of a nitrogen source to said solution before its solidification to provide from 1 to about 40 weight percent equivalent protein in said supplement.
Claim 16
Dependent Claim 145 words
A solid animal feed supplement consisting essentially of molasses, and solidifying ingredients sequentially added thereto as a soluble calcium reactant selected from the class consisting of calcium oxide and calcium hydroxide, in an amount from 1.0 to about 5.0 weight percent, expressed as the oxide and a soluble phosphate or phosphoric acid in an amount from 0.5 to about 5.0 weight percent expressed as P 0, with a proportion of equivalent weights of phosphate to metal from 1.0 to about 4.0, sufficient to react with said calcium reactant and solidify said supplement into solid block form and magnesium oxide added subsequent to commencement of said reaction between said calcium reactant and phosphate or phosphoric acid and prior to solidification of said molasses, in an amount from 2 to about 15 weight percent, sufficient to increase the hardness of said solid product to inhibit its consumption.
Claim 17
Dependent Claim 145 words
A solid animal feed supplement consisting essentially of molasses, and solidifying ingredients sequentially added thereto as a soluble calcium reactant selected from the class consisting of calcium oxide and calcium hydroxide, in an amount from 1.0 to about 5.0 weight percent, expressed as the oxide and a soluble phosphate or phosphoric acid in an amount from 0.5 to about 5.0 weight percent expressed as P 0, with a proportion of equivalent weights of phosphate to metal from 1.0 to about 4.0, sufficient to react with said calcium reactant and solidify said supplement into solid block form and magnesium oxide added subsequent to commencement of said reaction between said calcium reactant and phosphate or phosphoric acid and prior to solidification of said molasses, in an amount from 2 to about 15 weight percent, sufficient to increase the hardness of said solid product to inhibit its consumption.
