Metabolic Fate of Parenterally Administered Sulphur-Containing Amino Acids in Sheep and Effects on Growth and Composition of Wool

Abstract

Intravenous or intraperitoneal infusions of either L-cysteine (2, 0 gjday) or L-methionine (2·5 gjday) for 20 days increased wool diameter and its length growth rate, the main increases occurring during the first 8 days of infusion. Thus parenteral administration of these amino acids is effective in stimulating wool growth.
