The aim of this study was to characterize and conduct comparative analysis of corn dried distillers‟ grains with / without solubles (DDGc and DDGSc). These two animal feedstuffs are the main by-products of bioethanol industry. Representative samples of these subproducts were taken from the largest Bulgarian distilleries and analysed for DM, CP, EE, CF, NFE, ash, nutritive value (energy and protein nutritive value), aminoacid profile (relative and absolute value) and mineral content (macro- and microelements). The chemical analyses were made following AOAC, 2002. The nutritional assessment of both feeds included calculation of energetic and protein values by total or particular chemical composition. Based on the results of the conducted analyses it was concluded that corn dried distillers‟ grains with solubles (DDGSc) is superior to corn dried distillers‟ grains (DDGc). Potential correlations should be searched between protein (CP, PDI and BPT) and energy (FUG and FUM) nutritional value of both feeds and the expected animal performance.
