Abstract
A stabilized somatotropin peptide aldehyde complex which provides prolonged release of the somatotropin and enhanced feed efficiency. The complex is prepared by dissolving the somatotropin and peptide aldehyde in water, isolating the complex from the aqueous solution, and crystalizing the product from alcohol. Specifically, the complex comprises porcine somatotropin and leupeptin and is particularly useful for enhancing feed efficiency in swine.
