Abstract | The aim of the experiment with maize silage, harvested at almost ideal dry matter content, was to determine the effect of the use of silage additives on the reduction of dry matter losses during fermentation and losses by aerobic degradation after opening the silo. Selected silage additives, biological, chemical and their combinations, were tested. The control was without additive. For each variant, the effectiveness of two application doses was tested. The silage fodder was stewed in special bags, which were then inserted into the silage mass. The experimental silages were stored in a silage mass for 14 months. Aerobic stability was measured for 7 days. All the time, the temperature was measured with special sensors. Dry matter losses were measured by weighing the samples at the beginning and at the end of the given monitoring period. Fermentation losses in maize silages averaged 3.94% dry weight. Losses were higher in the no- additives control (5.53%) and the inoculant variant (4.45%) than in the other variants, but were not signifi cant. Aerobic degradation losses averaged 0.94% dry weight. In the control and variant with inoculant, the onset of aerobic degradation was faster, in the other variants the increase in temperature was gradual. A temperature above 2 oC, which is a criterion for aerobic stability, occurred in the control in 55 hours, in the variant with inoculant in 24 hours and with citric acid in 10% concentration in 113 hours. |
