Abstract: The field of the invention relates to processes for preparing Asparagopsis oil compositions, comprising extracting at least one bioactive from a biomass of Asparagopsis into an oil to form the compositions. These compositions are suitable for reducing total gas production and/or methane production in a ruminant or pseudo-ruminant animal.

Abstract: The invention relates to utilising red marine macroalgae to provide improvements in growth performance.

Abstract: The invention relates to utilising red marine macroalgae to provide improvements in growth performance of livestock, particularly ruminant animals for red meat production, especially cattle, in pasture and feedlot farming systems. There is provided a method for improving the growth performance of a livestock animal in a farming system including: providing a red marine macroalgae to a farming system to enable consumption of the red marine macroalgae by a livestock animal in the farming system; thereby improving the growth performance of the livestock animal in the system.

Abstract: A method of protecting a polymer surface against fouling, which method comprises embedding in the polymer surface particles having antifouling properties, wherein the particles are embedded in the polymer surface by a spray mechanism in which the particles are accelerated and sprayed onto the polymer surface with a suitable velocity such that the particles become embedded in the polymer surface, wherein the particles are embedded in the polymer surface without an adhesive or binder and wherein the particles do not form a continuous layer on the polymer surface.
