DDGS Economics : DDGS Economics SBM vs DDGS for protein supplement 44.8% vs 29% CP, $200 vs $105/ton Cost for SBM/lb CP (DM basis) = 22.3 cents Cost for DDGS/lb CP (DM basis) = 19.1 cents (Assume 90% Dry Matter) To offer a ewe an additional 0.2 lb/day of CP (DM basis) it would require: SBM= 0.45lb (As-fed basis) = 0.045 cents DDGS= 0.70lb (As-fed basis) = 0.039 cents For a 154 lb ewe fed 6 lb of feed (4% of body weight) during lactation the DDGS would make up 12.5 % of the ration. Well within the recommended feeding level. Recommendations for DDGS use in the ewe flock : Recommendations for DDGS use in the ewe flock Late Gestation (154 lb ewes) - add 0.1 lb (DM) of crude protein = 0.37 lb DDGS (similar to recommendations for winter grazing research at Montana State Univ.) Lactation (154 lb ewes) - add 0.2 lb (DM) of crude protein = 0.75 lb DDGS -Rear twin bearing ewes separate and use best forage to improve milk production/lamb survival. The crude protein needs and energy needs are much higher compared to single bearing ewes. -By using DDGS for protein supplementation it also is serving to replace some forage. Since the energy is similar to corn, for every 1lb of DDGS replaces 1.4 lb or more hay.
