Abstract

A low inclusion animal feed binder composed of ozonated lignosulfonate. The ozonated lignosulfonate is a reaction product of lignosulfonate and ozone prepared by treating lignosulfonate with 2-20% ozone by weight of lignosulfonate solids at an initial pH of 2 to 12 and at a temperature of 5° to 100° C. The binder is incorporated with the animal feed in an amount from 0.01 to 2% by weight of dry feed.

Claims

1. A method of compounding feed for animals, comprising the steps of

providing an animal feed comprising a protein-containing organic meal,

incorporating with said animal feed an effective amount of a binder to form a feed mixture, said feed binder is an ozonated lignosulfonate, wherein said ozonated lignosulfonate is lignosulfonate that has been treated with 2 to 20% ozone by weight of lignosulfonate solids, at an initial pH of 2 to 12 and at a temperature of 5°

C. to 100°

C.;

and forming said mixture into a desired pellet form.

2. The method of claim 1 wherein said binder is incorporated in an amount of 0.01 to 2% on weight of feed.

3. The method of claim 1 wherein said ozonated lignosulfonate is prepared by ozonolysis of lignosulfonate-containing spent sulfite liquor.

4. The method of claim 3 wherein said spent sulfite liquor is purified by fermentation or ultrafiltration.

5. The method of claim 1 wherein said ozonated lignosulfonate is prepared by ozonolysis of a lignosulfonate in the form of a sodium, potassium, calcium or ammonium salt.

6. The method of claim 1 wherein said binder is in a powder form.

7. The method of claim 1 wherein said ozonated lignosulfonate is prepared by ozonolysis of a sulfonated lignin.

8. The method of claim 1 wherein said ozonated lignosulfonate is lignosulfonate that has been treated with 5-10% ozone by weight of lignosulfonate solids, at an initial pH of 5 to 10, and at a temperature of 20°

C. to 50°

C.

9. The method of claim 1 wherein said binder is incorporated in an amount of 0.05 to 0.5% on weight of feed.

10. An animal feed composition, comprising a protein-containing organic meal, and an ozonated lignosulfonate binder produced by ozonolysis of lignosulfonate with 2-20% ozone by weight of said lignosulfonate.

11. The composition of claim 10 wherein about 0.01 to 2% on dry weight basis of said binder is incorporated with said animal feed.

12. The composition of claim 10 wherein said lignosulfonate is obtained by fermentation or ultrafiltration of spent sulfite liquor.

13. The composition of claim 10 wherein said ozonated lignosulfonate is prepared by ozonolysis of a spent sulfite liquor.

14. The composition of claim 10 wherein said ozonated lignosulfonate is prepared by ozonolysis of a sulfonated lignin.

15. The composition of claim 10 wherein said binder is an ozonated lignosulfonate produced by ozonation of lignosulfonate with 5-10% ozone by weight of said lignosulfonate.

16. The composition of claim 10 wherein 0.05 to 0.5% on dry weight basis of said binder is incorporated with said animal feed.
