  5. WDGS, modified (45% DM) • WDGS, traditional (35% DM) • DDGS (25% solubles) • Syrup, distillers solubles, CCDS • WCGF (45% DM) • WCGF-Sweet Bran (60% DM) • DCGF • Steep • “new” distillers grains Byproducts

  6. Use • Inclusion < 15% (2-3 lb): protein • Inclusion > 15% (4+ lb): energy

  15. UNL Meta Analysis of WDGS Effect on Carcass Characteristics Virgil Bremer, Galen Erickson&Terry Klopfenstein

  16. UNL Studies Used

  17. Average Daily Gain ADG (lb) Diet DM % WDGS Intercept cov. P = 0.03 L P < 0.01 ≠ 0 P < 0.01 Q P < 0.01

  18. Feed Conversion F:G (lb/lb) Diet DM % WDGS Intercept cov. P = 0.04 L P < 0.01 ≠ 0 P < 0.01 Q P = 0.09

  19. Marbling Score Marbling Score 500 = Small0 Diet DM % WDGS Intercept Slope cov. P = 0.08 cov. P = 0.09 L P = 0.05 ≠ 0 P < 0.01 Q P = 0.05

  20. UNL Meta Analysis of WCGF Effect on Carcass Characteristics Virgil Bremer, Galen Erickson&Terry Klopfenstein

  21. UNL Studies Used

  22. Average Daily Gain ADG (lb) Diet DM % WCGF Intercept cov. P = 0.05 L P < 0.01 ≠ 0 P < 0.01 Q P = 0.67

  23. Feed Conversion F:G (lb/lb) Diet DM % WCGF Intercept cov. P = 0.05 L P = 0.03 ≠ 0 P < 0.01 Q P = 0.48

  24. Feedlot Diets Issues • Fat (oil) • Sulfur • Phosphorus • Feed with DRC or HMC • Feed wet locally Nebraska opportunity Nebraska opportunity Nebraska opportunity

  25. How do we use more? Fat limits WDGS to 40% Sulfur is a concern Feed combination of byproducts Feed "new" distillers products

  26. WCGF/WDGS combination (%DM) BP (50:50 Blend) Loza et al., 2003

  27. WCGF/WDGS combination ADG BP Loza et al., 2003

  28. WCGF/WDGS combination Feed Conversion Q = <0.05 L = 0.32 BP (%DM) Loza et al., 2003

  29. New Economic Models for Performance Crystal Buckner, Galen Erickson, Terry Klopfenstein, Darrell Mark

  30. Economics for WDGS $19.28 Corn at $3.70/bu; WDGS at 95% of corn price; Lines are distance (miles) from ethanol plant to feedlot

  31. Impact of DGS on P challenge Land Requirements, 4yr P basis (acres) Feedlot size (hd): 2500 0 byp 0.30 P 1,320 20 byp 0.40 P 1,900 40 byp 0.50 P 2,500 Assumes: 50% of land area accessible 185 bu corn, corn-soybean rotation, ~35 lb P per acre (80 lb P2O5) Kissinger et al., 2006 NE Beef Report

  33. Feed Forms of “Regular” Distillers Grains

  34. WDGS in combination with other ingredients when stored in a silo bag or bunker silo Baga Bunker Grass hay, % 15.0 (6.5) 30-40 (17.0) Wheat straw, % 12.5 (5.5) 25-32 (13) Alfalfa hay, % 22.5 (10.2) 45-55 Dry distillers grains,% 50 (28) --- Corn gluten feed, % 60 (53.8) --- a300 PSI. Wet distillers grains at 35% dry matter 65% moisture Red percentages are “as-fed” basisAdams et al. University of Nebraska

  38. Issues • Byproducts will be here • Improve performance • Not negative on quality (related to • performance) • Don't forget about WCGF • Dry byproducts are different • Distillers grains will not be created equal • Energy content better than corn • Should be economical! PRICE DM!

  39. Nebraska Advantages • Can feed wet byproducts • Fits with “Nebraska” diets • dry-rolled corn, high-moisture corn • Manage the P here • Can feed even higher levels • WCGF and WDGS combination
