The sustained growth of the ethanol industry in the upper Midwest is well documented. There are many ways this affects the cattle industry. Increased demand for corn by the industry has driven prices to record highs in 2008. The increased cost and demand for corn have forced cattle producers to evaluate the many ways to use the by-products produced by the ethanol industry. Increased ethanol production has led to larger supplies of the byproduct dried distillers grains with solubles (DDGS). Companies have started to market pelleted versions of this product that may be economical for cattle producers to use to extend pastures while cheapening gains. The increase in pelleted products has led to easier ways to transport, store, and feed these products to grass cattle. This study was designed to evaluate the effect of feeding midrange levels of pelleted DDGS to heifers under southern Iowa grazing conditions.
