A comparative study was made of the sulfur requirements of growing-fattening lambs in terms of methionine, sodium sulfate, and elemental sulfur, added to a purified ration containing 4% urea. The gains on five levels of each of the sulfur sources fitted a quadratic curve. On the basis of the fitted curves, the calculated sulfur percentage requirement was for methionine 0.64±0.048, for sodium sulfate 1.2 7±0.44, and for elemental sulfur 0.47±0.028, respectively. On the basis of total sulfur about 70% less sulfur was needed as methionine in the diet than as elemental sulfur, or about 50% less as sulfate sulfur. The data suggest that sodium sulfate may be used more efficiently than elemental sulfur. 
Satisfactory agreement was found between the sulfur requirements of growing-fattening lambs as reported in studies of two different years.
