Abstract
Abstract An animal feed supplement in a solid, weather resistant block form and method of making is disclosed. The molasses based feed supplement block, intended for consumption primarily by ruminant animals, although not limited thereto, contains ferrous sulfate as a blocking agent. The feed supplement also comprises a water absorbent clay, a phosphorous source and magnesium oxide as well as an edible fat or oil in sufficient quantities to set into a solid block form in less than one hour at room temperature when admixed with the blocking agent. A preferred block composition is prepared by a method which comprises admixing the molasses, water, phosphorous source and water absorbing clay under high speed shearing action for an effective amount of time to disperse the clay, admixing edible fat and dispersing it in the mixture and then admixing ferrous sulfate and magnesium oxide to obtain a viscous nutrient mixture that thickens quickly. The mixture is then poured into molds or packages and solidifies within one hour at room temperature to form a hard block.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
A process for preparing an animal feed block which comprises mixing about 18 to 65% by weight molasses, about 4 to 9% by weight monobasic salt of phosphoric acid, about 0.5 to 5% by weight water absorbent clay and 5 to 20% water under high speed shearing action for an effective amount of time to disperse the clay, admixing 5 to 30% animal fat, about 8% by weight ferrous sulfate and about 3 to about 15% by weight magnesium oxide to obtain a viscous nutrient mixture that solidifies to form a hard weather resistant block within one hour at room temperature, said block having a water activity of from 0.8 to 0.9.
Claim 2
Dependent Claim
112 words
A process for preparing an animal feed block which comprises mixing about 18 to 65% by weight molasses, about 4 to 9% by weight monobasic salt of phosphoric acid, about 0.5 to 5% by weight water absorbent clay and 5 to 20% water under high speed shearing action for an effective amount of time to disperse the clay, admixing 5 to 30% animal fat, about 8% by weight ferrous sulfate and about 3 to about 15% by weight magnesium oxide to obtain a viscous nutrient mixture that solidifies to form a hard weather resistant block within one hour at room temperature, said block having a water activity of from 0.8 to 0.9.
