Abstract
Abstract There is disclosed a method for the manufacture of a solid animal feed supplement employing an in-situ reaction between a hydratable metal oxide such as calcium oxide and a water soluble phosphate, such as phosphoric acid to solidify the product. The method comprises the addition of the metal oxide to a concentrated dispersion of a water soluble sugar such as molasses, whey and the like, to hydrate the metal oxide. After sufficient hydration has occurred to provide the desired quantity of reactant metal ions in soluble form, a condition which can be detected by monitoring the pH, temperature, or time following addition of the metal oxide, the soluble phosphate is added to cause solidification of the resultant mixture.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
171 words
The method of preparing a solid animal feed supplement block product which comprises the steps of: (a) admixing at least about 0.5 weight percent based on the supplement product of a metal oxide selected from the class consisting of magnesium oxide, aluminum oxide, calcium oxide and mixtures thereof with an aqueous sugar solution containing from 10 to about 90 weight percent sugar; (b) hydrating said metal oxide to provide a sugar solution with soluble metal ions having a pH value from 9 to about 11; (c) thereafter reacting said solution with a monoalkali metal or ammonium orthophosphate or phosphoric acid at a concentration, expressed as P 2 O 5 , from 2 to about 5 weight percent based on the supplement product sufficient to react with said soluble metal ions and produce a product having a pH value from 3 to about 6, the amounts of said phosphate additive and metal ions being sufficient to solidify said supplement into a solid block; and (d) recovering a solid feed supplement block product.
Claim 2
Independent Claim
171 words
The method of preparing a solid animal feed supplement block product which comprises the steps of: (a) admixing at least about 0.5 weight percent based on the supplement product of a metal oxide selected from the class consisting of magnesium oxide, aluminum oxide, calcium oxide and mixtures thereof with an aqueous sugar solution containing from 10 to about 90 weight percent sugar; (b) hydrating said metal oxide to provide a sugar solution with soluble metal ions having a pH value from 9 to about 11; (c) thereafter reacting said solution with a monoalkali metal or ammonium orthophosphate or phosphoric acid at a concentration, expressed as P 2 O 5 , from 2 to about 5 weight percent based on the supplement product sufficient to react with said soluble metal ions and produce a product having a pH value from 3 to about 6, the amounts of said phosphate additive and metal ions being sufficient to solidify said supplement into a solid block; and (d) recovering a solid feed supplement block product.
Claim 3
Dependent Claim
26 words
The method of claim 1 including the step of adding from 5 to about 20 weight percent based on the supplement product of an animal-edible fat.
Claim 4
Dependent Claim
12 words
The method of claim 2 wherein said animaledible fat is yellow grease.
Claim 5
Dependent Claim
12 words
The method of claim 2 wherein said animaledible fat is palm oil.
Claim 6
Dependent Claim
12 words
The method of claim 1 wherein said metal oxide is calcium oxide.
Claim 7
Dependent Claim
41 words
The method of claim 5 wherein said metal oxide is added with a water soluble salt of said metal the proportions being such that the metal equivalent from the oxide should be at least 1.5 the equivalent of said salt coadditive.
Claim 8
Dependent Claim
59 words
The method of claim 1 including the step of adding a member selected from the group consisting of urea, biuret, ammonium phosphate, dried blood, cottonseed meal, soy meal, dehydrated alfalfa, dried and sterilized chicken manure, fish solubles, cell cream and rabbit pellets to said solution to provide from 5 to about 40 weight percent equivalent protein in said supplement.
Claim 9
Dependent Claim
22 words

Claim 11
Dependent Claim
34 words
The method of claim 1 wherein phosphoric acid is added to the mixture of said sugar solution and metal oxide when the pH of said mixture reaches a value from 9.5 to about 10.5.
Claim 12
Dependent Claim
34 words
