Method and composition for preventing and treating avian influenza in poultry

1. A method for treating and reducing the risk of avian influenza in a poultry, comprising a step of administering to said poultry an effective amount of a composition comprising an anti-avian influenza ingredient containing a polyphenolic selected from the group consisting of theaflavin, theaflavin-3,3′-digallate, theaflavin-3-monogallate, theaflavin-3 gallate, theaflavin-3′-gallate, thearubigin, gallic acid, tannic acid, (−)-epigallocatechin gallate (EGCG), (−)epigallocatechin (EGC), (+)-epicatechin (EC), (−)-gallocatechin gallate (GCG), catechin, and combinations thereof, wherein the composition is administered directly to poultry by inhalation.

2. The method of claim 1 , wherein the composition comprises the anti-avian influenza ingredient in combination with a carrier.

3. The method of claim 2 , wherein the composition comprises 98.0% by weight of the carrier and 2.0% by weight of the anti-avian influenza ingredient.

4. The method of claim 1 , wherein the polyphenolic is extracted from tea leaves.

5. The method of claim 3 , wherein the polyphenolic is extracted from tea leaves.

6. The method of claim 1 , wherein theaflavin, theaflavin-3,3′-digallate, theaflavin-3 gallate, thearubigin, gallic acid, and tannic acid are extracted from black tea.

7. The method of claim 3 , wherein theaflavin, theaflavin-3,3′-digallate, theaflavin-3 gallate, thearubigin, gallic acid, and tannic acid are extracted from black tea.

8. The method of claim 1 , wherein (−)-epigallocatechin gallate (EGCG), (−)epigallocatechin (EGC), (−)epicatechin gallate (ECG), (+)-epicatechin (EC), (−)gallocatechin gallate (GCG), and catechin are extracted from green tea.

9. The method of claim 3 , wherein (−)-epigallocatechin gallate (EGCG), (−)epigallocatechin (EGC), (−)epicatechin gallate (ECG), (+)-epicatechin (EC), (−)gallocatechin gallate (GCG), and catechin are extracted from green tea.

10. A method for treating and reducing the risk of avian influenza in a poultry, comprising a step of administering to said poultry an effective amount of a composition comprising an anti-avian influenza ingredient containing a polyphenolic selected from the group consisting of theaflavin, theaflavin-3,3′-digallate, theaflavin-3-monogallate, theaflavin-3 gallate, theaflavin-3′-gallate, thearubigin, gallic acid, tannic acid, (−)-epigallocatechin gallate (EGCG), (−)epigallocatechin (EGC), (+)-epicatechin (EC), (−)-gallocatechin gallate (GCG), catechin, and combinations thereof, wherein the composition is administered directly to poultry by injection.

11. The method of claim n, wherein the composition comprises the anti-avian influenza ingredient in combination with a carrier.

12. The method of claim 11 , wherein the composition comprises 98.0% by weight of the carrier and 2.0% by weight of the anti-avian influenza ingredient.

13. The method of claim 10 , wherein the polyphenolic is extracted from tea leaves.

14. The method of claim 12 , wherein the polyphenolic is extracted from tea leaves.

15. The method of claim 10 , wherein theaflavin, theaflavin-3,3′-digallate, theaflavin-3 gallate, thearubigin, gallic acid, and tannic acid are extracted from black tea.

16. The method of claim 12 , wherein theaflavin, theaflavin-3,3′-digallate, theaflavin-3 gallate, thearubigin, gallic acid, and tannic acid are extracted from black tea.

17. The method of claim 10 , wherein (−)-epigallocatechin gallate (EGCG), (−)epigallocatechin (EGC), (−)epicatechin gallate (ECG), (+)-epicatechin (EC), (−)gallocatechin gallate (GCG), and catechin are extracted from green tea.

18. The method of claim 12 , wherein (−)-epigallocatechin gallate (EGCG), (−)epigallocatechin (EGC), (−)epicatechin gallate (ECG), (+)-epicatechin (EC), (−)gallocatechin gallate (GCG), and catechin are extracted from green tea.
