The effect of cystine administered per os on the milk secretion has been determined for the milk yields of twelve lactating goats. It has been shown that cystine is unable to stimulate, Tactn atipn of, the animals on the standard diet supplemented daily by 0.5 or 1.0g. of L-cystine for nine days. This compound was indicated to be slightly capable of increasing milk-fat and casein, and the animals require only about 0.5g. of cystine daily per head to initiate visible secretion of the milk constituents. Evidences have been presented which indicate that the response of the test animals to cystine is not highly sensitive, and that the substance seems-not to be utilizable for dairy industry.
