Distillers dried grains protein content range:

Distillers dried grains protein content range:

• A. 22-29% CP
• B. 15-20% CP
• C. 30-40% CP
• D. 10-15% CP

Answer: (A)

Distillers dried grains are a high-protein byproduct of ethanol production, so their crude protein content is well above that of the original grain. In typical DDG products, CP sits in the low to mid-20s up to the high-20s percent, and commonly falls around the low-to-mid 20s or upper 20s depending on processing. The range that best captures this common level is 22-29% CP, which reflects the high-protein nature of DDG without venturing into the much higher values seen in some other protein sources. The other ranges are not representative of DDG’s usual protein content: 15-20% is too low for this byproduct, 30-40% is higher than typical DDG values, and 10-15% is far too low.
