  1. Use of Soybean Products in Diets fed to Swine Hans H. Stein University of Illinois http://nutrition.ansci.illinois.edu

  2. Outline • Composition of soybeans • New varieties of soybeans • Effect of soybean oil on the digestibility of AA • Fermented and enzymatically treated soybean meal in diets for weanling pigs • Soybean meal (SBM) in the US and other countries • Effect of particle size of SBM on AA and energy digestibility

  3. Composition of Soybeans

  4. Soybeans and Soybean Meal

  5. Sugar and Oligosaccharides • Free sugars: 4.5% • Sucrose: 4.5% • Galacto-oligosaccharides: 4.5% • Raffinose 0.6% • Stachyose 3.7% • Verbascose 0.2%

  6. Effect of StachyoseWeanling pigs, 21 d post-weaning a b c Liying et al., 2003

  7. Effect of StachyoseWeanling pigs, 21 d post-weaning a b c Liying et al., 2003

  8. Soybeans with no Oligosaccharides • Select soybeans with low concentration of oligosaccharides • Remove genes for oligosaccharides • Remove oligosaccharides after crushing When oligosaccharides are removed, the concentration of sugar and protein is usually increased.

  9. New Varieties of Soybeans

  25. Removal of Oligosaccharides via Fermentation or Enzymatic Hydrolysis Cervantes–Pahm and Stein, 2010

  26. Fermentation of SBM • Addition of bacteria and fermentation (Fx. Aspergillus Oryzae and Bacillus subtillis) • PepSoyGen • Reduced size of proteins • Reduced concentration of oligosaccharides • Probiotic effect • Reduced concentration of antigenic substances Treatment of SBM with enzymes (and fermentation) • HP 300 • Reduced concentration af antigenic substances
