Replacement of Grazed Forage and Animal Performance when Distillers Grains are fed in a Bunk or on the Ground

A 120-day grazing experiment estimated forage savings, performance, and ground feeding efficiency when supplementing spayed yearling heifers with modified distillers grains with solubles (MDGS) at 0.6% of BW on native Sandhills range. Supplemented heifers had 1.28 lb greater ADG and consumed 15.9% less forage. Each 1 lb of MDGS supplement fed replaced approximately 0.7 lb of forage. Loss of MDGS when ground-fed was 4.3%. Supplementing spayed yearling heifers with MDGS at 0.6% BW decreased forage consumption 15.9% and increased gain.
