Abstract

A method for improving the immune response of an animal to a vaccine, comprising: feeding an animal a diet of contamination-resistant feed, and treating said animal with an anti-viral or anti-bacterial vaccine.

Claims

1. A method for increasing the level of antibodies in eggs, colostrum or milk produced in response to a vaccination, comprising:

maintaining a breeding animal on a diet of contamination-resistant feed, and treating said breeding animal with a vaccine.

2. The method of

claim 1

, wherein said vaccine is selected from the group consisting of a vaccine against Marek'"'"'s disease, Newcastle disease-infectious bronchitis, laryngotracheitis, avian encephalomyletis, fowl pox, pseudorabies, influenza, transmissible gastroenteritis, porcine reproductive and respiratory syndrome, foot and mouth disease, and parvovirus.

3. The method of

claim 1

, wherein said vaccine is a bacterin selected from the group consisting of Salmonella enteritidis, Salmonella cholerasuis, Streptococcus suis, Escherichia coli, Mycoplasma galliseptum, Mycoplasma hyopneumonia, Erysipelas, Bordetella, Leptosprias species, Actinobacillus pleuropneumonia and Hemophilis species.

4. The method of

claim 1

, wherein said diet consists of formaldehyde-treated feed having a coefficient of variation of 5% or less.

5. The method of

claim 1

, wherein the animal is a bird selected from the group consisting of chicken, turkey and duck.

6. The method of

claim 1

, wherein the breeding animal is a cow, sheep, pig or horse.

7. A method for improving the immune response of an animal to a vaccine, comprising:

feeding an animal a diet of contamination-resistant feed, and treating said animal with a vaccine.

8. The method of

claim 7

, wherein said vaccine is selected from the group consisting of a vaccine against Marek'"'"'s disease, Newcastle disease-infectious bronchitis, laryngotracheitis, avian encephalomyletis, fowl pox, pseudorabies, influenza, transmissible gastroenteritis, porcine reproductive and respiratory syndrome, foot and mouth disease, and parvovirus.

9. The method of

claim 7

, wherein said vaccine is a bacterin selected from the group consisting of Salmonella enteritidis, Salmonella cholerasuis, Streptococcus suis, Escherichia coli, Mycoplasma galliseptum, Mycoplasma hyopneumonia, Erysipelas, Bordetella, Leptosprias species, Actinobacillus pleuropneumonia and Hemophilis species.

10. The method of

claim 7

, wherein said diet consists of formaldehyde-treated feed having a coefficient of variation of 5% or less.

11. The method of

claim 7

, wherein the breeding animal is a bird selected from the group consisting of chicken, turkey and duck.

12. The method of

claim 7

, wherein the animal is a cow, sheep, pig or horse.

13. A method for improving the absorption of antibodies by a neonatal animal from egg yolk, colostrum or milk, comprising:

maintaining a breeding animal on a diet of contamination-resistant feed, and vaccinating said breeding animal with an effective amount of a vaccine.

14. The method of

claim 13

, wherein said vaccine is selected from the group consisting of a vaccine against Marek'"'"'s disease, Newcastle disease-infectious bronchitis, laryngotracheitis, avian encephalomyletis, fowl pox, pseudorabies, influenza, transmissible gastroenteritis, porcine reproductive and respiratory syndrome, foot and mouth disease, and parvovirus.

15. The method of

claim 13

, wherein said vaccine is a bacterin selected from the group consisting of Salmonella enteritidis, Salmonella cholerasuis, Streptococcus suis, Escherichia coli, Mycoplasma galliseptum, Mycoplasma hyopneumonia, Erysipelas, Bordetella, Leptosprias species, Actinobacillus pleuropneumonia and Hemophilis species.

16. The method of

claim 13

, wherein said diet consists of formaldehyde-treated feed having a coefficient of variation of 5% or less.

17. The method of

claim 13

, wherein the neonatal animal is a bird selected from the group consisting of chicken, turkey, and duck.

18. The method of

claim 13

, wherein the neonatal animal is a cow, sheep, pig or horse.
