Method for increasing wool production and quality, and the liveweight of lambs

摘要

Wool production, in terms of both quality and quantity, and also liveweight, are improved in lambs by administration of a coated amino acid, especially methionine or lysine. The coating may comprise a basic amino copolymer (especially copoly (styrene/vinylpyridene)) or zein and a hydrophobic substance of melting point greater than 60 DEG C (especially stearic acid), and/or a water-insoluble polymer (especially ethylcellulose).
