Abstract
Abstract An improved liquid feed supplement composition for ruminant animals and a method for its preparation wherein water, urea and an aldehyde are reacted in the presence of a catalyst which is effective to promote a reaction between the urea and the aldehyde and which also provides nutrients for the ruminant, and in the presence of molasses.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
106 words
A method for the preparation of a liquid feed supplement composition for ruminants, comprising the steps of reacting a reaction mixture consisting essentially of water, urea and a lower aliphatic aldehyde selected from the group consisting of formaldehyde, acetaldehyde, propionaldehyde and mixtures thereof, wherein the mole ratio of the aldehyde to the urea ranges up to 5.5, in the presence of molasses and 0.001 to 1.0 parts by weight of a catalyst selected from the group consisting of phosphoric acid, ammonium sulfate, ammonium phosphate and ammonium polyphosphate per part by weight of urea for a time sufficient to permit the urea to react with the aldehyde.
Claim 2
Independent Claim
106 words
A method for the preparation of a liquid feed supplement composition for ruminants, comprising the steps of reacting a reaction mixture consisting essentially of water, urea and a lower aliphatic aldehyde selected from the group consisting of formaldehyde, acetaldehyde, propionaldehyde and mixtures thereof, wherein the mole ratio of the aldehyde to the urea ranges up to 5.5, in the presence of molasses and 0.001 to 1.0 parts by weight of a catalyst selected from the group consisting of phosphoric acid, ammonium sulfate, ammonium phosphate and ammonium polyphosphate per part by weight of urea for a time sufficient to permit the urea to react with the aldehyde.
Claim 3
Independent Claim
108 words
A method for the prepartion of a liquid feed supplement composition for ruminants comprising the steps of reacting a reaction mixture consisting essentially of water, urea and formaldehyde in the presence of molasses and in the presence of a catalyst selected from the group consisting of phosphoric acid, ammonium sulfate, ammonium phosphate and ammonium polyphosphate, wherein the mole ratio of the formaldehyde to the urea is up to 5.5 and the catalyst is present in an amount within the range of 0.001 to 1 parts by weight of catalyst per part by weight of urea, for a time sufficient to permit the urea to react with the aldehyde.
Claim 4
Independent Claim
108 words
A method for the prepartion of a liquid feed supplement composition for ruminants comprising the steps of reacting a reaction mixture consisting essentially of water, urea and formaldehyde in the presence of molasses and in the presence of a catalyst selected from the group consisting of phosphoric acid, ammonium sulfate, ammonium phosphate and ammonium polyphosphate, wherein the mole ratio of the formaldehyde to the urea is up to 5.5 and the catalyst is present in an amount within the range of 0.001 to 1 parts by weight of catalyst per part by weight of urea, for a time sufficient to permit the urea to react with the aldehyde.
Claim 5
Dependent Claim
30 words
A method as defined in claim 2 wherein at least a portion of the urea is added to the mixture in the form of a pre-condensation product with an aldehyde.
Claim 6
Dependent Claim
24 words
A method as defined in claim 2 wherein the mole ratio of the aldehyde to urea is within the range of 0.5 to 5.5.
Claim 7
Dependent Claim
121 words
A liquid feed supplement composition consisting essentially of water-soluble urea-aldehyde condensates and finely divided water-insoluble urea-aldehyde condensates dispersed in molasses, with the aldehyde being selected from the group consisting of formaldehyde, acetaldehyde, propionaldehyde and mixtures thereof, said composition having been prepared by reaction of a reaction mixture consisting essentially of water, urea and the aldehyde in the presence of molasses and in the presence of a catalyst selected from the group consisting of phosphoric acid, ammonium sulfate, ammonium phosphate and ammonium polyphosphate, wherein the mole ratio of the aldehyde to urea ranges up to 5.5 and the catalyst is present in an amount within the range of 0.001 to 1 part by weight of catalyst per parts by weight of urea.
Claim 8
Dependent Claim
121 words
A liquid feed supplement composition consisting essentially of water-soluble urea-aldehyde condensates and finely divided water-insoluble urea-aldehyde condensates dispersed in molasses, with the aldehyde being selected from the group consisting of formaldehyde, acetaldehyde, propionaldehyde and mixtures thereof, said composition having been prepared by reaction of a reaction mixture consisting essentially of water, urea and the aldehyde in the presence of molasses and in the presence of a catalyst selected from the group consisting of phosphoric acid, ammonium sulfate, ammonium phosphate and ammonium polyphosphate, wherein the mole ratio of the aldehyde to urea ranges up to 5.5 and the catalyst is present in an amount within the range of 0.001 to 1 part by weight of catalyst per parts by weight of urea.
