Distillers Grains Feeding Recommendations. - Distillers Grains By ...

Similar calculations can be made for UIPExample:DDGS (where UIP is 55% of CP)$/lb of UIP in DDGS = $150/ton / (2000 lb x .92 x .28 x .55)= $.53/lb of UIP2. Equation to price DDGS in relation to corn (energy source) and soybean meal (CP source).All feeds must be priced on a common unit basis ($/cwt or $/ton) and on an equal DM basissuch as air dry (90% DM).Corn = $7.14/cwtSoybean meal = $12.50/cwt$/cwt of DDGS = ($ of corn x .531) + ($/cwt of soybean meal x .514)= ($7.14 x .531) + $12.50 x 514)= $10.22/cwt or $204.40/ton3. Another way of pricing DDGS based on protein and energy is against a mix of soybeanmeal, corn and fat which is equal in CP and energy to the DDGS. An example of a 100 lbmix equivalent to DDGS of 25% CP, 9% fat and 86 Mcal of NE L (as fed basis) is:lb/100 lb$/100 lbof mix x $/lb = of mixSoybean meal 47.5 x .1250 = 5.94Corn 46.0 x .0714 = 3.28Tallow 6.5 x .25 = 1.62TotalFeeding Wet Distillers Grains$10.84 / 100 lb of DDGSFor some dairy producers, feeding wet distillers grains (WDG) directly from an alcohol plantmay be an option. Very little information is available on feeding WDG, especially to dairy cattle.Klopfenstein and Stock (12) summarized several studies conducted by the authors on feedingWDG to feedlot cattle. Dry matter content of WDG averaged 31.4%. Nutrient composition ofWDG is slightly different than DDG. The WDG fed in their research studies contained morestarch and ethanol and less protein than typically found in DDG. The energy value for gaindetermined from feeding trials was 1.28 to 1.69 times greater for WDG than corn. Nodifferences in protein efficiency were found between DDGS and WDG when fed to growingcalves. As with any high moisture feed, the handling, storage, storage loss and transportationcosts must be considered in the usage and economic value of WDG.9
