The present disclosure relates to a feed additive composition for reducing methane production generated in the ruminant stomach of ruminant animals. Specifically, the present disclosure relates to a feed additive composition for reducing methane production comprising at least one selected from the group consisting of alliin and berberine, more specifically to a feed additive composition for reducing methane production comprising at least one selected from the group consisting of diallyl disulfide (DADS), nitrate, and eucalyptus oil. The feed additive composition according to the present disclosure may be added to the feed without additional treatment, thereby reducing the amount of methane production in the ruminant stomach without negative effects on livestock productivity. Thus, the feed additive composition can be effectively used in the ruminant animal industry.

The present invention relates to a feed supplement or a food supplement which comprises a resin acid based composition comprising over 10% (w/w) resin acids for use in in the prevention of intestinal disorders. The invention further relates to a use of the feed supplement or the food supplement and a feed composition or a food composition comprising the feed supplement or the food supplement, respectively.

A method of reducing methane production in a ruminant animal, comprising administering a methane reducer to a ruminant animal by proportionally dosing the methane reducer into a drinking water supply for the ruminant animal at a dosing rate selected to deliver the methane reducer to the ruminant animal in an effective manner.

The present invention includes the complete genome sequence for the methanogen, Methanobrevibacter ruminantium, including polynucleotides which encode M. ruminantium polypeptides or peptides, as well as polynucleotides from non-coding regions. Also included are the encoded M. ruminantium polypeptides and peptides, and antibodies directed to these peptides or polypeptides, in addition to expression vectors and host cells for producing these peptides, polypeptides, polynucleotides, and antibodies. The invention further includes methods and compositions for detecting, targeting, and inhibiting microbial cells, especially methanogen cells such as M. ruminantium cells, using one or more of the disclosed peptides, polypeptides, polynucleotides, antibodies, expression vectors, and host cells.

Compositions for reducing the emission of methane by ruminant animals are disclosed. The compositions include avian antibodies against methanogens generally found in the rumen of the animals. Egg contents of eggs from female birds inoculated with immunogenic compositions containing one or more methanogens or antigens derived from methanogens are used. The antibodies in the egg contents may be used directly without further purification, may be partially purified or purified. The compositions may be administered in drinking water or in animal feed. Administering of the anti-methanogenic composition reduces the emission of methane and increases the efficiency of feed conversion.

The present invention relates to the field of reduction of methane emission in ruminants. Particularly, it relates to the administration of gossypol and a methane inhibitor to a ruminant for reducing the production of methane emanating from the digestive activities of said ruminant.

The present invention relates to the field of reduction of methane emission in ruminants. Particularly. it relates to the administration of gossypol in an amount of at least 7.5 g gossypol/animal/day to a ruminant for reducing the production of methane emanating from the diges-5tive activities of said ruminant.

The present disclosure provides novel compositions for the reduction of enteric methane and methods for supplementing animal feed that result in significant reduction in methane emissions in ruminants supplemented with compositions of the present invention.

Methane production from ruminant digestion is reduced by allowing a ruminant to be fed on feed containing unfermented coffee grounds.

The present invention discloses a multiplier and modulator additive of the ruminal microbiota created from exogenous multienzyme compounds, integrating processes and devices for cultivating and harvesting biomass of selected fungal species, assembling active components of fungal origin and by mixing supplies according to specifications, forming thus a multiplier and modulator additive of the ruminal microbiota suitable for its application (as part of food or via distribution devices as a nutritional supplement) in the ruminant animal feed industry.
