This study focuses on the impact of product development of DG in adoption, inclusion, and displacement rates. We also want to estimate what savings in feed cost, if any, can be attributed to the use of DG in a finishing hog ration. It was found that inclusion of DDGS in a feed ration saves feeder-finisher operations $2.17 per head if traditional DDGS is used and $8.06 per head if newer generation DDGS products are used. Finally, with their higher substitution and displacement rates, newer-generation DDGS products can better alleviate the trade-off between food, feed, and fuel in the
continuing expansion of biofuels.
