The aim of this work was to study the effects of temperature on the aerobic stability of wheat and corn silages. Three silage samples from each crop were taken from the faces of six different commercial bunker silos immediately after unloading them. The samples were exposed to air for 3 or 6 days at 10, 20, 30 or 40 degrees C. The most intensive deterioration occurred at 30 degrees C. Samples incubated at 30 degrees C had the highest yeast counts, most prolific CO2 production and greatest increases in pH. Silage samples exposed to 10 or 40 degrees C remained stable. The duration of exposure had a significant effect on aerobic stability, especially at 30 degrees C. Temperature has a significant effect on silage aerobic stability. In a warm climate, special care should be taken during unloading of silage in order to prevent intensive aerobic deterioration.
