Abstract

There is provided a method of treating hay for preventing and/or reducing heat damage in high moisture hay and as well to preserve the same, the method including adding to hay a hay preservative including a hay preserving and heat reducing effective amount of at least one enzyme having a chitinase activity, either alone or in combination with a hay preserving and heat reducing effective amount of a yeast of the genus Pichia or a bacteria of the genus Pediococcus . There is also provided a method of treating hay for preventing and/or reducing heat damage in high moisture hay and as well to preserve the same, the method including adding to hay a hay preservative including a hay preserving and heat reducing effective amount of yeast of the genus Pichia.

First claim

The invention claimed is:

1. A hay preservative composition comprising an enzyme with chitinase activity and a yeast of the genus Pichia or a bacteria of the genus Pediococcus , wherein the
chitinase activity is in the range of about 6 U to 250 U per ton of hay to be treated and the amount of either
Pichia or Pediococcus is 10 5 to 10 15 viable organisms per ton of hay to be treated and wherein the composition is effective to reduce the heat of the hay.

2. The hay preservative composition of claim 1 , wherein the Pichia is Pichia anomala.

3. The hay preservative composition of claim 2 , wherein the Pichia anomala is Pichia anomala (Accession number DBVPG 3003).

4. The hay preservative composition of claim 1 , wherein the Pediococcus is Pediococcus pentosaceus.

5. The hay preservative composition of claim 4 , wherein the Pediococcus pentosaceus is Pediococcus pentosaceus BTC328 (Accession number NCIMB 12674) or Pediococcus pentosaceus BTC401 (Accession number NCIMB 12675).

6. The hay preservative composition of claim 1 , further comprising at least one enzyme having a Pectin lyase activity, a Glucanase activity, or a mixture thereof.

7. The hay preservative composition of claim 1 comprising a high moisture hay.

8. The hay preservative composition of claim 7 further comprising an effective amount of Pichia.

9. The hay preservative composition of claim 8 , wherein the Pichia is Pichia anomala.

10. The hay preservative composition of claim 9 , wherein the Pichia anomala is Pichia anomala (Accession number DBVPG 3003).

11. A method of reducing heat damage in high moisture hay comprising adding the composition of claim 1 to high moisture hay.

12. The method of to claim 11 , wherein the Pichia is Pichia anomala.

13. The method of claim 12 , wherein the Pichia anomala is Pichia anomala (Accession number DBVPG 3003).

14. The method of claim 11 , wherein the Pediococcus is Pediococcus pentosaceus.

15. The method of claim 14 , wherein the Pediococcus pentosaceus is Pediococcus pentosaceus BTC328 (Accession number NCIMB 12674) or Pediococcus pentosaceus BTC401 (Accession number NCIMB 12675).

16. The method of claim 11 , wherein the heat preserving composition further comprises at least one enzyme having a Pectin lyase activity, a Glucanase activity, or a mixture thereof.
