Method for increasing wool production and quality, and¹liveweight 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).
