Abstract: An animal feed supplement composition comprising a phospholipid composition having a specific ratio of components as defined below: Phosphatidylcholine 18±1; Phosphatidylethanolamine 14±1; Lysophosphatidylcholine 1±1; Lysophosphatidylethanolamine 1±1; Lysophosphatidylinositol 2±1. The phospholipid composition provides an improved animal feed which has beneficial effects on animal performance.

Abstract: An acylamino acid for enhancing the bio-availability of substances in organisms by permeabilization of cell membranes, the acylamino acid having general formula (I) wherein R1 is hydrogen, a primary, secondary or tertiary alkyl or alkenyl group and R2 is hydrogen, a straight or branched chain alkyl group or a straight or branched chain substituted alkyl group, the substituted being selected from thio, thioether, hydroxy, carboxy, quarternary ammonium, amide, heterocyclic, benzyl, substituted benzyl, amino, substituted amino groups and difunctional alkyl groups linking to the nitrogen atom. A preferred acylamino acid for incorporating into an animal or fish feed is 2-palmitoylaminoproprionic acid.

Abstract: An animal feedstuff contains a minor amount of a lysophospholipid that has growth promoting properties when fed to animals. The lysopbospholipid is produced from a kit that can be incorporated into an animal feed, where the kit includes a substrate and a bacterial strain that is capable of producing an enzyme capable of converting the substrate into the lysophospholipid.
