The present invention relates to a tall oil fatty acid for use in the prevention of growth of harmful bacteria in the animal digestive tract and/or in the prevention of intestinal disorders. The invention further relates to a feed supplement and a feed composition comprising tall oil fatty acid.

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 disclosure provides compositions and methods for reducing emissions of deleterious atmospheric gases and/or precursors thereof from a flooded ecosystem comprising: one or more small molecules that reduce the production of one or more deleterious atmospheric gases and/or precursors thereof and one or more agriculturally suitable carriers.

Some embodiments of the present livestock structures comprise a floor, wherein the floor is configured to support livestock housing; a roof, wherein a majority of the roof is substantially parallel to the floor; and one or more supporting structures configured to support the roof; in some embodiments, the floor comprises a non-zero slope. Some embodiments of the present livestock structures comprise a passageway extending a majority of a distance between a first side and an opposing second side of the structure, wherein the passageway is positioned at an elevation that is below an elevation of the floor.

Compositions are formed of a compressed mixture which includes a powderous formulation of a carrier and 3-nitrooxypropanol or derivatives thereof as an active ingredient, and a gluten. The composition remains intact in water after 24 hours.

Polyurethane foam flakes for use as additive to soil and/or other natural plant growth media for improving the water retention and/or reduction of the methane emission.

The present invention relates to a method of reducing total gas production and/or methane production in a ruminant animal.

A method for reducing methane production in a ruminant animal comprising the step of administering to said ruminant animal an effective amount of at least one strain of bacterium of the genus Propionibacterium.

The invention generally relates to compositions and methods for reducing methane production in animals, in particular by controlling oxidation-reduction potential in the digestive tract.

The present invention relates to Iodoform for use in a method of reducing methane production in and/or for improving performance of a ruminant, said method comprising the step of administering to the ruminant iodoform in an effective amount in the range of 5-100 mg of iodoform/kg DM. The present invention also relates to a method of reducing methane production in and/or for improving performance of a ruminant, and to a feed additive for a ruminant.
