Abstract

Disclosed are compositions, kits, and methods for enhancing growth in an animal in need thereof. The methods typically comprise administering orally to the animal a composition comprising biodegradable particles, the biodegradable particles comprising a polymer or a co-polymer comprising polymerized lactic acid and having an effective average diameter of 0.5-5 μm. In the methods, the animal is administered a dose of the biodegradable particles that is effective for improving feed conversion rate in the animal in comparison to an animal that is not administered the composition.
