The material of the study consisted of corn and wheat bale silages after 75-days fermentation period. Silage samples in each treatment group, including three replications 7-8°C, 24-25°C and 32-33°C temperature and were subjected to an aerobic stability test. Analyzes of chemical and microbiological parameters was carried out in silage samples at days 0, 1, 4, 6, 12 and 15 of aerobic stability. At the same time, evaluation results were recorded for each treatment group by a thermal imaging camera (T200 IR) at a distance of 1 m
