Abstract

The objective of this experiment was to compare the effects of 5 commonly used sulfur (S) sources in research trials: dry distillers grains with solubles (DDGS), condensed distillers solubles (CCDS), sulfuric acid, sodium sulfate, and calcium sulfate, on ruminal pH and hydrogen sulfide (H2S) concentrations. While diet and ruminal pH did differ among the treatments, there was no difference among S sources in ruminal H2S concentrations measured 6 hours post-feeding. These data suggest that there is no difference in the potential for S toxicity among the different S sources used in this study.
