Comparing Dry, Wet, or Modified Distillers Grains Plus Solubles on Feedlot Cattle Performance

Abstract

Three types of distillers grains (DG): 1) wet distillers grains plus solubles (WDGS), 2) dried distillers grains plus solubles (DDGS), or 3) modified distillers grains plus solubles (MDGS), included at 3 levels: 20%, 30%, or 40% the diet DM, and a corn-based control compared the effect of drying distillers grains on feedlot performance. Type of DG had no effect on ADG (P = 0.30), but DMI increased for MDGS and DDGS compared to WDGS (P < 0.01). Therefore, F:G was improved for WDGS (P < 0.01) compared to MDGS and DDGS. Gain was greater and F:G was lower when DG were fed compared to the corn control. The feeding value of WDGS was 35.4% and 17.8% greater than DDGS and MDGS, respectively. The feeding value was 45.7%, 26.5%, and 9.3% more than corn for WDGS, MDGS, and DDGS, respectively.
