The aim of this research was to determine the fatty acid content in maize silages of different hybrids.  Grain hybrid with FAO number 420 and silage hybrid with stay-green maturation with FAO number 450 were evaluated. Maize hybrids were grown under the same agro-ecological conditions, and harvested on growing degree days 1277 (FAO 420) and 1297 (FAO 450).  Whole-plant maize was chopped to 10 mm by harvester with kernel processor and immediately ensiled in plastic barrels (volume 50 dm³). Maize matter was ensiled without silage additives. For fatty acids analyses samples of maize silages were taken after 8 week of ensiling. Content of fatty acids was quantified by gas chromatography. Examined maize of both hybrids had the highest linoleic acid content, followed by oleic acid and third highest content of palmitic acid. The results confirmed differences in fatty acid content in maize silages of different hybrids. In silages of grain hybrid was detected significantly higher content of palmitic acid and cis-11-eicosenoic acid and significantly lower content of oleic acid in compared with silage of silage hybrid. This ultimately resulted in a higher polyunsaturated fatty acids content (P < 0.05) in maize silage from grain hybrid and lower monounsaturated fatty acids content (P < 0.05) in maize silage from stay green hybrid.
