Reduction of boar odor in meat

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.

Stabilized somatotropin for parenteral administration

A novel antibiotic complex of 'vancomycin-like' antibiotics, AAD 216 complex, is produced by the cultivation of a fermentation broth containing Kibdelosporangium aridum Shearer gen. nov., sp. nov. ATCC 39323 microorganisms in an aqueous nutrient medium under submerged aerobic conditions. The AAD 216 complex and its major bioactive components; AAD 216A, AAD 216B, and AAD 216C exhibit antibiotic activity and growth promotant activity.

Antibiotics produced by Kibdelosporangium aridum Shearer gen. nov., sp.

Cysteamine is used as an active ingredient in animal feed compositions and in methods for increasing the feed efficiency of immature, monogastric, meat-producing animals. A particularly useful active ingredient of this invention is cysteamine hydrochloride in a quantity selected from the range of 15-1200 ppm.

Animal feed methods and compositions using cysteamine

Selected pyridylalkylhydrazides are used as active ingredients in animal feed compositions and in methods for increasing the growth and feed efficiency of monogastric, meat-producing animals. A particularly useful active ingredient of this invention is 3-azabicyclo-[3.2.2]nonane-3-carbothioic acid 2-[1-(2-pyridyl)ethyl]-hydrazide.
