Abstract: 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 of a ruminant animal, 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.

Abstract: This invention relates to use of a strain of lactic acid bacteria for 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 ruminal methane production and/or for improving feed efficiency, milk production, and/or body weight or body composition of a ruminant animal. Ruminant feed compositions are also provided.

Abstract: This invention relates to use of a strain of lactic acid bacteria for inhibiting the growth of methane-producing bacteria and/or archaea in the gastrointestinal tract of monogastric animals, reducing the ability of the microbiome of the gastrointestinal tract to produce methane, reducing methane production or emissions, and/or for improving feed efficiency, and/or body weight or body composition of a monogastric animal.

Abstract: The present invention relates to a method of pressure treating a bioactive composition comprising at least one bioactive component to prevent the growth of at least one unwanted microorganism while retaining a desired level activity of the at least one bioactive component. The bioactive component is selected from one or more proteins protein hydrolysates, one or more lipids or lipid hydrolysates, one or more carbohydrates, one or more probiotic factors, or mixtures thereof. The pressure treatment is at a predetermined pressure from about 350 to 1000 MPa.
