摘要

Method, composition and kit for increasing lean muscle mass and / or reducing fat gain in a growing animal and means for transmitting information or instructions. Compositions and methods for increasing lean muscle mass and / or reducing gain in growing animals by feeding the animals with a composition having a total lysine to metabolizable energy ratio of about 2.5 to about 6 g / Mcal and comprising (a) arginine in a total arginine to total lysine ratio of from about 1.1 to about 1.6; (b) isoleucine and a ratio of total isoleucine to total lysine from about 0.8 to about 1.3; (c) leucine in a total leucine to total lysine ratio of from about 1.8 to about 3.0; (d) valine in a total valine ratio of from about 0.8 to about 1.1; and (e) methionine and cystine in a ratio of total methionine plus cystine to total lysine from about 0.8 to about 1.7.
