Summary and Implications
The data support the conclusion that supplementing a rumen-protected vitamin C (VC) source to yearling feedlot steers consuming a high sulfur (S; 0.55%) diet tends to increase feed efficiency and ribeye area (REA), while minimal effects were noted on blood metabolites or marbling score.
