Feed composition for reducing ruminant methanogenesis
The present invention refers to a method for reducing methane production in ruminants comprising administering to said ruminant a feed composition containing a flavanone glycoside.
1. A method for reducing methane production in a ruminant comprising:
administering orally to said ruminant a feed composition, wherein said feed composition is a mixture comprising neohesperidin and poncirin, and wherein said ruminant exhibits reduced methane production upon oral administration of the feed composition.
2. The method according to claim 1 , wherein said mixture additionally comprises naringin.
3. The method according to claim 1 , wherein said mixture is a natural plant extract.
4. The method according to claim 3 , wherein said natural plant extract is a citrus plant extract.
5. The method according to claim 1 , wherein said feed composition additionally comprises a carrier.
6. The method according to claim 5 , wherein said carrier is sepiolite.
7. The method according to claim 1 , wherein said ruminant is a calf, a cow, a buffalo, a sheep, a deer, a camel or a goat.
8. The method according to claim 7 , wherein said ruminant is a calf.
9. The method according to claim 1 , wherein said feed composition is added to feed in solid form at a concentration of 50 to 1000 mg/Kg dry matter.
10. The method according to claim 1 , wherein said feed composition is added to feed in solid form at a concentration of 200 to 500 mg/Kg dry matter.
11. The method according to claim 2 , wherein said mixture is a natural plant extract.
12. The method according to claim 11 , wherein said natural plant extract is a citrus plant extract.
13. The method according to claim 2 , wherein said feed composition additionally comprises a carrier.
14. The method according to claim 13 , wherein said carrier is sepiolite.
15. The method according to claim 2 , wherein said ruminant is a calf, a cow, a buffalo, a sheep, a deer, a camel or a goat.
16. The method according to claim 15 , wherein said ruminant is a calf.
17. The method according to claim 2 , wherein said feed composition is added to feed in solid form at a concentration of 50 to 1000 mg/Kg dry matter.
18. The method according to claim 2 , wherein said feed composition is added to feed in solid form at a concentration of 200 to 500 mg/Kg dry matter.
19. The method according to claim 2 , wherein said feed composition is a mixture comprising 25 to 55% wt. of naringin, 10% to 20% wt. of neohesperidin, 1% to 5% wt. poncirin and sufficient quantity up to 100% wt. of a carrier.
20. The method according to claim 19 , wherein said feed composition comprises 40 to 50% wt. of naringin, 11 to 15% wt. of neohesperidin, 3 to 5% wt. of poncirin and sufficient quantity up to 100% wt. of a carrier.
21. The method according to claim 2 , wherein said feed composition is a mixture comprising 20% wt. of naringin and 40% wt. of bitter orange extract, wherein the bitter orange extract comprises 25 to 27% wt. of naringin in respect of the total amount of bitter orange extract, 11 to 13% wt. of neohesperidin in respect of the total amount of bitter orange extract, and 3 to 5% wt. of poncirin in respect of the total amount of bitter orange extract.
