Summary and Implications

Eighty-eight fall born Angus heifers were used in a grazing study to evaluate supplementation of two levels of distillers dried grains with solubles (DDGS) supplemented on Southern Iowa pastures. The levels of supplementation were none (CONT), .5% of body weight (MED) and 1.1% of body weight (HIGH). Stocking rates were increased 22% and 44% for the MED and HIGH treatments compared to controls. Daily gains were 1.13, 1.30 and 1.47 lb. per day for CONT, MED and HIGH treatments. It appeared that cattle fed the HIGH level of supplementation had reduced pasture consumption, whereas MED levels did not. At current costs the HIGH level was more effective than MED at lowering cost per lb. of gain. Supplementation of DDGS improved cattle performance, but levels above .5% of body weight were necessary to substitute for pasture in this study.
