 Votes so far: For:(0) Against:(0)
Claims: What is claimed is:

1. A process for preparing nutrient compositions for feeding animals which comprises preparing a dry mixture containing 35 to 48 parts of urea with 65 to 52 parts of urea phosphate, melting the urea-urea phosphate mixture so obtained at a temperature of from 72.degree. to 90.degree.C, absorbing the molten mixture in an animal feed material, and cooling the feed material containing the mixture.

2. A process according to claim 1 wherein the urea-urea phosphate mixture is a crystalline material containing about 61.5 percent urea and 38.5 percent of 100 percent phosphoric acid.

3. A process according to claim 2 wherein the crystalline material is prepared by reacting at a temperature of about 50.degree. to about 80.degree.C, phosphoric acid containing from about 45 to about65 percent P.sub.2 O.sub.5 with sufficient urea to provide a mixture containing from 64 to 60 percent urea and from 36 to 40 percent phosphoric acid, cooling the aqueous mixture so obtained to precipitate urea-urea phosphate crystals, and separating the crystals from the aqueous liquid.

4. A process according to claim 1 wherein during the cooling a basic material is added.

5. A process according to claim 4 wherein the basic material is soda, lime, magnesia, potash, or two or more of such basic materials.

6. A process according to claim 1 wherein a basic material is added to the molten urea-urea phosphate mixture before absorption of the molten mixture in the animal feed material.

7. A process according to claim 6 wherein the basic material is soda, lime, magnesia, potash, or two or more of such basic materials.

8. A process according to claim 1 wherein at least one sulfate is added to the molten mixture so as to obtain a ratio of nitrogen to sulfur in the final product of at least 13:1.

9. A process according to claim 1 wherein nutritional trace elements are added to the molten mixture.

10. A process according to claim 1 wherein vitamins A, D, E, or two or more thereof are added to the cooled feed material.

11. A process according to claim 1 wherein molasses is added to the feed material in the proportion of 0.1 to 20 parts of molasses to 100 parts of feed material containing the urea-urea phosphate mixture.

12. A process according to claim 1 wherein the molten urea-urea phosphate is dispersed onto the surface of particles of the feed material.

13. A process according to claim 1 wherein the animal feed material is cellulosic.

14. A process according to claim 1 wherein the animal feed material is Chinese hemp palm kernel cake.
