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.
Claims18
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.sub.2 O.sub.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.
