Implication

Controlled trial demonstrates that distillers grains outperform corn supplements in growing steers grazing corn residue, suggesting rumen undegradable protein drives gain.

Key Points

Distillers grains with solubles and SoyPass enhance weight gain in grazing steers far more effectively than whole corn, while supplemental urea provides no added benefit.
Steers fed distillers grains achieved an average daily gain of 1.05 kg/d at higher intake, whereas unsupplemented controls lost 0.08 kg/d during cornstalk residue grazing.
Evaluation across two grazing trials showed that rumen degradable protein is unnecessary with distillers grains, indicating rumen undegradable protein drives cattle growth.
