Assessing Potential Sulfur Intake Excess

The assessment of sulfur intake excess in beef cattle requires estimation of total sulfur concentration (TSC) to determine if there could be a hazard.

The maximum tolerated level is 0.4% sulfur as dry matter intake (DMI).

It is important to account for all potential sulfur sources from feed and water. TSC is expressed as % sulfur of DMI, and is estimated by adding the sulfur contributed by the water (%SH2O) to sulfur contributed by the feed or forage (%SFF), all on a DM basis.

Our sulfur calculator can complete this calculation.
