Antimicrobial enzymes in animal feed

摘要

The use of two antimicrobial enzymes for use in feed for monogastric or non-ruminant animals is disclosed to improve growth and feed conversion ratio of poultry, pigs, veal calves and fish. This may enable the farmer to avoid the use of growth promoting antibiotics. The enzymes have antibacterial activity and one can disrupt the cell wall of bacteria (eg. lysozyme) with another producing a compound toxic to bacteria (eg. oxidase). The efficacy of these enzymes is enhanced by the inclusion of a polyunsaturated fatty acid (PUFA) such as arachidonic acid.
