Abstract: Nowadays, several experiment shown, that grape pomace have potential as a feed in animal nutrition and could be good source of nutrient with beneficial antioxidant activity. Thus, the aim of the research was to compare nutritional value of Pinot Blanc (Vitis vinifera sp.) pomace from two different localities of Slovakia (Vinohrady nad Váhom and Oponice). In the samples content of crude protein (CP), ether extract (EE), crude fibre (CF), ash (A), nitrogen free extract (NFE), acid detergent fibre (ADF), neutral detergent fibre (NDF), lignin (L), cellulose (C) and hemicellulose (H) according to standard analytical methods were determined. After the evaluation of results it can be concluded, that between different locations of grape pomace statistically significant results were found. The biggest and statistically significant differences in the case of CP (4.87%; p<0.05), EE (16.37%; p<0.01) were determined. However, larger differences in the case of ADF (41.56%; p<0.01), NDF (49.99; p<0.01), L (8.88%; p<0.01), C (428.85%; p<0.01) and H (110.63%; p<0.01) were found. The biggest ratio of organic matter was consisted from NFE in both localities. However, ratio of EE and CP in the second locality was higher in comparison with the first locality.
