Summary and Implications

Sulfur (S) is an essential element in ruminant diets, but it can be toxic at high levels. Sulfur also interacts with other minerals in the diet such as copper (Cu), impacting the status of the animal. This study utilized 96 crossbred yearling steers fed a low sulfur diet (LS, 0.3% S) or the LS diet with additional S from sodium sulfate creating a high S diet (0.6% S, HS) to determine the effects of S concentration on performance, carcass quality, and mineral status. High S decreased gains and Cu and magnesium (Mg) status. Decreased gains may result in more days on feed to finish cattle when feeds high in S are used. Dietary S impacts on mineral status may also further impact animal health.
