Forage from genetically modified (GM) maize in two consecutive years (1999 and 2000) was ensiled in bins of 120 l volume in two combinations: with formic acid (85%) and without. In the samples of ensilage material GM maize, basic parameters have been determined such as pH and dry matter. The determination of biological activity of the components of translational apparatus in model translation systems showed the complete inactivation of biological activities. In addition, degradation of nucleic acids in examined silages was discovered.
