The present invention relates to a tall oil fatty acid which is modified by saponification 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 which is modified by saponification.

An animal emission monitoring device for positioning on cattle, the animal emission monitoring device comprising a snout member comprising a sensor unit for detecting the quantity of methane emissions and a positioning means for positioning the device on the head of an animal such that the snout member locates the sensor unit over the nostril of the animal.

A method of reducing production of carbon dioxide or methane from farmed animals, including administering to an animal a formulation of carbon dioxide or methane reducing concentrations of vitamin K. The method reduces the carbon dioxide and/or the methane in one or more of breath exhalant of the animal, faeces of the animal, and from soil on which the faeces have been deposited. M ethane production is reduced by at least 20% by volume and carbon dioxide production is reduced by at least 20% by volume. The vitamin K is formulated to be isolated until the vitamin K reaches to gut of the animal whereupon it is formulated to be released and mix with stomach or rumen fluid. The method increases animal weight gain over time, inhibits or prevents production of skatole compounds production from metabolism of the animal over time, and reduces production of offensive odours from animal faeces.

The present invention relates to a method of reducing methane emissions in ruminants, said method encompassing treating pre-/young ruminants with 3-nitrooxypropanol.

The present disclosure provides methods for reducing methane emissions from a ruminant comprising administering to the ruminant a composition comprising a fungal strain, wherein the fungal strain comprises a vanadium-dependent haloperoxidase (VHPO) such as Curvularia sp. strain 4388 (NMI Accession No. V22/011149). The disclosure also provides a cell or a biologically pure culture of Curvularia sp. strain 4388 (NMI Accession No. V22/011149) or a mutant thereof having all identifying characteristics of the strain.

A premix is disclosed. The premix includes a nitrate compound and salts thereof in the amount of greater than about 50% by weight of the premix. The premix also includes vitamins and trace minerals. The premix is formulated for use in at least one of a gestation or lactation phase of an animal and in an amount of less than about five percent by weight (5.0 wt %) inclusion per metric ton of the premix. A supplement for an animal feed for feeding during at least one of an animal's gestation phase and/or lactation phase is also disclosed. A method for feeding an animal is also disclosed.

The present invention concerns novel probiotic compositions that increase nitrate- and nitrite-reduction in animals such as ruminants. The present invention thus provides compositions and methods for reducing nitrate/nitrite toxicity in such animals, or prophylactically protecting such animals from the effects of toxicity, such as methemoglobinemia. A novel strain of an unspeciated bacterial strain related to Paenibacillus species with nitrate- and nitrite-reducing capabilities is described. In conjunction with nitrate-supplemented diets, the probiotics of the present invention can also be utilized to reduce methanogenesis in livestock. Furthermore, the probiotic compositions of the present invention can be used to reduce the number and kind of food-borne pathogens, such as Escherichia coli and Campylobacter jejuni.

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.

This invention relates to use of a strain of probiotic bacteria or derivatives thereof for increasing feed efficiency, enhancing growth and/or productivity, improving body weight or body composition, and/or increasing milk production in a ruminant animal, inhibiting the growth of methane-producing bacteria and/or archaea in the forestomach of ruminant animals, reducing the ability of the rumen microbiome to produce methane, reducing methane emissions by a ruminant animal, and/or reducing the greenhouse gas emission footprint of a ruminant animal. Ruminant feed compositions are also provided.
