Alfalfa protein is relatively low in the sulfur-containing amino acids, and the alfalfa's nutritive value may thereby be limited. This has been indicated at several laboratories in biological assays—feeding tests with small animals. Increasing the sulfur content of alfalfa, therefore, may improve its value as a feed.
