Abstract
A finishing trial evaluated wet corn gluten feed (WCGF) and roughage inclusion levels in diets containing 30% modified distillers grains plus solubles (MDGS, DM basis) using a 3 x 3 factorial treatment structure. No significant WCGF x roughage level interactions were observed. There was a quadratic response due to WCGF level for dry matter intake (DMI) and average daily gain (ADG), which were lowest for cattle fed 30% WCGF; however, feed-gain ratio (F:G) increased linearly with increasing WCGF. Gain responded quadratically and was lowest for cattle fed 0% corn silage. F:G and DMI increased linearly with increasing corn silage. Feedlot performance was improved by feeding 0% or 15% WCGF compared to 30% WCGF in finishing diets containing 30% MDGS. The optimal level was 7.5% corn silage in diets containing 30% MDGS with or without WCGF.
