Spayed heifers were developed into yearlings by grazing corn residue and bromegrass, followed by native range, and were finished on a common diet. Treatments were 2 lb or 5 lb of wet distillers grains with solubles (WDGS; DM basis) supplement on corn residue daily, and modified distillers grains with solubles (MDGS) fed at 0.6% BW daily or no MDGS during summer grazing. Feeding 5 lb increased winter ADG by 0.68 lb (year 1) or 0.40 lb (year 2) compared to 2 lb, and increased HCW after finishing. Summer supplementation increased summer ADG by 0.50 lb (year 1) or 0. 44 lb (year 2), but increased F:G during finishing. There were no differences in DMI, DOF, or marbling.
