  4. 4. US perspective
  5. 5. Nebraska perspective• Plants spread out • Wet & Modified predominate• In historical corn areas • Expansion has been west• Near feedlot cattle

  8. 8. Focus• Perception is: • “we have too much” • grain ethanol is “old news” & mature industry• Adapt to higher grain prices• Use more • limitations: fat, sulfur, N losses, optimal performance• Effect of drying • performance • GHG emissions (relative to gasoline) for whole system• Impact of using distillers • environmental issues (nutrient management) • meat quality issues (shelf-life and sensory traits) • food safety • other dietary ingredients to optimize performance
  9. 9. Usage Potential• 70.6 million tons (all livestock) • 25 million tons (feedlot cattle)• Produced from 21 billion gallon ethanol• 7.8 billion bushels corn• 50%+ of corn crop
  10. 10. Effect of drying Meta-analysis• WDGS • 20 experiments, 3,365 steers, 350 pens• DDGS • 4 experiments, 581 steers, 66 pens• MDGS • 4 experiments, 680 steers, 85 pens Bremer et al., 2011 Prof. Anim. Scient.
