The mean CP, CF, EE, and TA of various DDGs samples were, 28.92, 7.68, 11.86, and 5.75, respectively. Similarly the calcium, phosphorous, sodium, potassium, magnesium and sulfur content of DDGs were 0.3, 0.61, 0.32, 0.82, 0.27, and 0.78, respectively. CNCPS fractionations revealed that DDGS can be effectively used as superior quality carbohydrate and protein source. The average in vitro digestibility coefficients of DM, CP, NDF and ADF were, 71.45, 78.96, 70.42, and 63.36%, respectively. Significant difference among the nutrient digestibility of samples studied by in-vitro digestibility and CNPS fractionation may be attributed to difference in processing procedures followed by the industrial plants.

International Journal of Livestock Research, 7(2), 164–171. doi:10.5455/ijlr.20170209071816 Introduction Distiller’s grains with soluble (DDGs) are the nutrient rich co-product of dry-milled ethanol production. India stands at seventh position in DDGS production (Renewable Fuels Association, 2015). As the dairy farmers are able to avail the DDGs at a very cheap price, there is an increasing trend in the usage of
