  1. BYPRODUCT FEEDS FROM GRAIN PROCESSING Pages 229-231

  2. Feed Grain Byproducts • Residual materials from grains after extraction of starch and/or oil • Processing concentrates remaining components • Protein • Fiber • Oil? • Minerals • Protein quality of byproduct feeds is no better than the initial grain • May contain additional components added in processing

  3. Corn ProcessingWet Milling

  4. Nutritional Composition of Byproduct Feeds from Wet Corn Processing

  5. Uses of Byproducts of Wet Corn Processing in Ration Formulation • Corn gluten feed • Beef cattle • Feedlot cattle • Limit to 30% of the diet DM in diets containing forage • Feed up to 90% of the diet DM in diets containing little or no forage (Monitor S status) • Grazing cows and growing cattle • Can comprise entire supplement • Dairy cattle • Lactating cows • Limit to 30% of the diet DM • Growing heifers • Can comprise entire supplement, but do not feed free-choice • Swine • Sows in gestation may receive as much as 90% CGF • Poultry • Layers may receive as much as 30% CGF

  6. Concerns with CGF • Storage of wet CGF • In outdoor pile, wet CGF needs to be fed within week • Can be ensiled by itself or mixed with forage • High sulfur content • Limits amounts fed to ruminants • High fiber content • Limits amounts fed to growing swine, poultry, and lactating dairy cows

  7. Corn gluten meal • Beef cattle • Feedlot • Can comprise 50% of the protein supplement • Provides rumen undegradable protein to cattle < 600 lb • Cows • Not cost-effective • No need for rumen undegradable protein • Dairy cattle • Lactating cows • Can comprise 50% of the protein supplement • Provides rumen undegradable protein • Swine • Limit to < 5% of diet • Lysine is limiting • Poultry • Limit to <5% of diet • Contains Xanthophyll • Imparts yellow pigment to skin and egg yolks

  8. Steep water • Beef cattle • Feedlot cattle • Limit to 12% of diet DM • Supplies energy and degradable N • Growing cattle and cows • Used in liquid supplements and protein tubs • Dairy cattle • Use up to 5% of diet • Swine • Can comprise 15% of the dry matter in liquid diets of growing-finishing pigs • Poultry • Can comprise up to 5% of diet

  9. Corn ProcessingDry Milling

  10. Nutritional Composition of Byproduct Feeds from Dry Corn Processing

  11. Uses of Byproducts of Dry Corn Processing in Ration Formulation • Distillers Grains with solubles • Beef cattle • Feedlot cattle • Limit to 40% of the diet DM • Limited by the S content • Grazing cows, growing cattle, and calves • Can comprise entire supplement • Dairy cattle • Lactating cows • Limit to 20% of the diet DM • Growing heifers • Limit to 15% of the diet DM • Do not feed wet DGS to heifers less than 6 mo • Swine • Growing-finishing • Limit to 20% of diet DM • Poultry • Limit to 15% of diet DM

  12. Concerns with feeding DDGS • Sulfur content • >.4% S in diet may be toxic to ruminants • Toxicity risk may be prevented by supplemented with Thiamin • Fat content • May reduce feed intake and fiber digestion in ruminants • May cause milk fat depression in lactating dairy cows • High level of unsaturated fatty acids may result in soft pork fat • Fiber content • Limits use in nonruminants • Phosphorus content • May cause urinary calculi in steers or lambs • Need to add calcium supplement • Aflatoxin • Concentrated 3 times the level in corn

  13. Acceptable Aflatoxin Levels in Corn or DDGS

  14. Condensed solubles • Beef cattle • Feedlot cattle • Limit to 10% of diet DM • Growing cattle and cows • Used in liquid supplements and protein tubs • Dairy cattle • Use up to 5% of diet of lactating cows • Swine • Can comprise 15% of the dry matter in liquid diets of growing-finishing pigs • Poultry • Not used
