A finishing study was conducted to evaluate the effects of feeding 0 or 20% field peas in dry-rolled corn-based diets with 0 or 30% wet distillers grains plus solubles (WDGS). There was an interaction for DMI, in which WDGS had no effect in diets without peas, but increased DMI by 2.7 lb in diets containing peas. Peas decreased DMI by 1.3 lb in diets with no WDGS but had no effecton DMI in diets containing WDGS. A peas × WDGS interaction also was observed for F:G with WDGS decreasing F:G by 12% in diets without peas, but having no impact in diets containing peas. Field pea inclusion decreased F:G by 4% in diets with no WDGS, but increased F:G by 4% when WDGS was present. The impact of WDGS on F:G was diminished in the presence of peas from 40% to 24% improvement relative to corn. However, the increase in ADG due to WDGS was similar with or without peas.
