Abstract

The aim of the experiment was to evaluate the fermentation and aerobic stability of alfalfa silages harvested in dry matter of about 50% with different chop lengths (4 and 2 cm) using selected silage preparations, in addition with different application rates. Lucerne fermented in sacks buried in the silage. During fermentation and aerobic degradation, the temperature was measured continuously with an accuracy of 0.065 °C. Two weeks after the closure of the silos, the silage temperature, inoculated with Lactobacillus plantarum MTD1 (ES), peaked at 41 °C. The temperature of the silage without additive (KO) peaked a week later. Over time, the temperature of the silage decreased, but the difference between the KO and ES variants increased. For shorter silage silages, the temperature reduction during fermentation was even higher when using an additive in combination sodium nitrite and Lactobacillus plantarum MTD1. The best quality indicators of the fermentation process were achieved for ES silage with shorter chop. Aerobic stability was worst in KO and with shorter chop (27 hours).
