Abstract

A method of making a gel-type livestock feed includes initially forming a feed mixture by mixing feed nutrient components, water, alginate, and a calcium component insoluble in water or a sequestrate to inhibit the calcium component from reacting with the alginate. Once the feed mixture is formed, the calcium component is solubilized or the sequestrates affecting the reactivity between the alginate and the calcium component is removed such that a gel feed is formed that includes a gel matrix containing the feed nutrient components. The gel feed may then be fed to the livestock. In another aspect of the present invention, piglets are weaned by feeding the gel feed for at least seven days directly after weaning. The gel feed may also include protein derived from blood with or without egg protein.

Claims (25)

1. A method of making a livestock feed for piglets, the method comprising:

forming a feed mixture by mixing feed nutrient components, a gelling agent, and a calcium salt which is initially insoluble in water but may be made soluble, wherein the gelling agent is a gum selected from the group consisting of alginate, carrageenan, gellan and pectin, and wherein during the step of forming the feed mixture the gelling agent does not react with the calcium salt; and

once the feed mixture is formed, causing the gelling agent and the calcium salt to react such that a gel feed is formed comprising a gel matrix in which the feed nutrient components are retained,

wherein the feed nutrient components comprise about 2 to 25% protein, about 3 to 40% carbohydrate, and about 0 to 10% fat.

2. The method of claim 1 , wherein causing the gelling agent and the calcium salt to react involves adding an acid to the feed mixture to lower a pH of the feed mixture.

3. The method of claim 2 , wherein the acid comprises citric acid, fumaric acid, propionic acid or any combination thereof.

4. The method of claim 2 , wherein sufficient acid is added to lower the pH to at least about 4.5 or below.

5. The method of claim 1 , wherein the calcium salt comprises dicalcium phosphate, calcium carbonate, calcium gluconate, calcium iodate, calcium sulfate or any combination thereof.

6. The method of claim 5 , wherein the calcium salt becomes soluble and reactive with the gelling agent at a selected pH and the pH of the feed mixture is lowered to or below the selected pH.

7. The method of claim 1 , wherein the feed nutrient components include water as a major component.

8. The method of claim 1 , wherein the feed nutrient components comprise about 25 to 90% water.

9. The method of claim 1 , wherein forming the feed mixture comprises adding antibiotics or chemotherapeutics.

10. The method of claim 1 , wherein the protein comprises protein derived from an animal, a plant or a combination thereof.

11. The method of claim 1 , wherein the gel feed is then fed to piglets during weaning, immediately after weaning or both.

12. A method of making a livestock feed for piglets, the method comprising:

forming a feed mixture by mixing feed nutrient components, a gelling agent, and a calcium salt which is initially insoluble in water but may be made soluble, wherein the gelling agent is a gum selected from the group consisting of alginate, carrageenan, gellan and pectin, and wherein the pH during mixing of the feed nutrient components is 6.0 or greater; and

once the feed mixture is formed, lowering the pH to solubilize the calcium salt such that the gelling agent reacts with the solubilized calcium salt and a gel feed is formed comprising a gel matrix in which the feed nutrient components are retained,

wherein the water is a major component of the gel matrix, and

wherein the feed nutrient components comprise about 2 to 25% protein, about 3 to 40% carbohydrate, and about 0 to 10% fat.

13. The method of claim 12 , wherein the calcium salt comprises dicalcium phosphate, calcium carbonate, calcium gluconate, calcium iodate, calcium sulfate or any combination thereof.

14. The method of claim 12 , wherein the pH is lowered to at least about 4.5 or below to solubilize the calcium salt.

15. The method of claim 12 , wherein the gel feed is then fed to piglets.

16. The method of claim 12 , wherein forming the feed mixture comprises adding antibiotics or chemotherapeutics.

17. The method of claim 12 , wherein the feed nutrient components comprise a protein derived from an animal, a plant or a combination thereof.

18. The method of claim 12 , wherein the gel matrix comprises about 25 to 90% water.
