Abstract: A feed material for livestock is effective in prevention and/or treatment of pathogenic infections in livestock and/or in increasing efficiency in livestock production. Enteral administration of polysaccharide butyryl esters to livestock animals results in increased butyrate concentrations in the lower intestinal tract. This leads amongst others to a reduced presence of pathogens in the lower intestinal tract and feces and superior growth performance results compared to other butyrate formulations or products. The feed material provides polysaccharide butyryl esters, compositions, such as feed additives and/or feed, having the polysaccharide butyryl esters, as well as the uses of the polysaccharide butyryl esters as feed additive, e.g. for preventing or treating pathogenic infections in livestock and/or in increasing efficiency in livestock production.

Abstract: A method and a device are disclosed for determining data representative of the layout of a road in a two-dimensional Cartesian coordinate system, the coordinate system being associated with a vehicle travelling along the road. To this end, a first set of first points in the Cartesian coordinate system is determined on the basis of data representative of at least one image of the road environment in front of the vehicle. A second set of second points is determined in the Cartesian coordinate system on the basis of mapping data of the road environment of the vehicle. The data representative of the road layout are obtained on the basis of a part of the first points and a part of the second points.
