The Physiological Effect of Rations Restricted Principally or Solely to the Alfalfa Plant
II. Cystine as a Limiting Factor in the Nutritive Value of Alfalfa Proteins*
J. R. Haag
(From the Department of Agricultural Chemistry, Oregon Agricultural Experiment Station, Corvallis.)
Numerous group and paired-feeding experiments have been conducted with rats, using rations containing alfalfa leaves to supply the proteins. These experiments are interpreted as demonstrating a deficiency of cystine in the mixed crude proteins of alfalfa.
