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 magnesium oxide as a blocking agent. The feed supplement also comprises a water absorbent clay, a phosphorous source and an edible fat or oil in sufficient quantities to set into a solid block in a relatively short period of time at ambient temperatures. 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 magnesium oxide to obtain a viscous nutrient mixture that thickens quickly. The mixture is then poured into molds or packages and solidifies to form a hard depackagable block.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 103 words
A process for preparing a molasses based feed block which comprises: admixing about 18 to 74% by weight molasses, a water soluble phosphorous source selected from the group consisting of ammonium polyphosphate and tetrasodium pyrophosphate, about 0.5 to 5% by weight water absorbent clay and 5-30% water under high speed shearing action for an effective amount of time to disperse the clay, admixing about 5 to 30% by weight animal fat and magnesium oxide in an amount effective to obtain a viscous nutrient mixture that solidifies to form a hard weather resistant block said block having a water activity of 0.8 to 0.9.
Claim 2
Dependent Claim 103 words
A process for preparing a molasses based feed block which comprises: admixing about 18 to 74% by weight molasses, a water soluble phosphorous source selected from the group consisting of ammonium polyphosphate and tetrasodium pyrophosphate, about 0.5 to 5% by weight water absorbent clay and 5-30% water under high speed shearing action for an effective amount of time to disperse the clay, admixing about 5 to 30% by weight animal fat and magnesium oxide in an amount effective to obtain a viscous nutrient mixture that solidifies to form a hard weather resistant block said block having a water activity of 0.8 to 0.9.
Claim 3
Dependent Claim 22 words
The process of claim 1 wherein the magnesium oxide is present in amounts ranging from about 5 to about 20% by weight.
Claim 4
Dependent Claim 19 words
The process of claim 1 wherein the magnesium oxide is present in the amount of about 6% by weight.
Claim 5
Dependent Claim 23 words
The process of claim 1 wherein the phosphorous source is ammonium polyphosphate in amounts ranging from about 2 to about 8% by weight.
Claim 6
Dependent Claim 23 words
The process of claim 1 wherein the phosphorous source is tetrasodium pyrophosphate in amounts ranging from about 1 to about 6% by weight.
Claim 7
Dependent Claim 78 words
An animal feed block comprising about 18 to 74% by weight molasses, 1 to 8% of a phosphorous source selected from the group consisting of ammonium polyphosphate and tetrasodium pyrophosphate, about 0.5 to 5.0% water absorbent clay, 5 to 30% water, about 5 to 30% fat and an effective amount of magnesium oxide to set the ingredients into a block, said block having a water activity of from 0.8 to 0.9 and being solid, weather resistant and palatable.
Claim 8
Dependent Claim 78 words
An animal feed block comprising about 18 to 74% by weight molasses, 1 to 8% of a phosphorous source selected from the group consisting of ammonium polyphosphate and tetrasodium pyrophosphate, about 0.5 to 5.0% water absorbent clay, 5 to 30% water, about 5 to 30% fat and an effective amount of magnesium oxide to set the ingredients into a block, said block having a water activity of from 0.8 to 0.9 and being solid, weather resistant and palatable.
Claim 9
Dependent Claim 23 words
The composition of claim 6 wherein the phosphorous source is ammonium polyphosphate in amounts ranging from about 2 to about 8% by weight.
Claim 10
Dependent Claim 23 words
The composition of claim 6 wherein the phosphorous source is tetrasodium pyrophosphate in amounts ranging from about 1 to about 6% by weight.
Claim 11
Dependent Claim 24 words
