Application of phospholipases in animal feed.

摘要

The present invention discloses a process for improving the efficiency of feed utilization and/or for promoting the growth of animals in which an animal is fed a diet which comprises a composition comprising feed substance and a ready for use phospholipase additive. Preferably said composition also comprises at least one phospholipid. Said compositions are used to improve fat digestibility and to promote growth of the animal. The phospholipid is preferably lecithin and the preferred phospholipase is a mammalian phospholipase A2. In a preferred embodiment the phospholipase is produced using recombinant DNA technology to express the enzyme in a suitable host such as a microorganism or a transgenic plant.
