|Abstract: ||Alkaline agents reduce the fiber content, but results in a buffering of the silage that can benefit the
growth of undesirable micro-organisms. The association of alkaline agents and additives capable of
inducing a decrease in the initial pH may be interesting. Our aim was to evaluate the effects of a wild
strain of Lactobacillus plantarum (UFLA SIL 1) and the addition of propionic acid on the fermentation
and aerobic stability of sugarcane silages treated with and without calcium oxide. Propionic acid
reduced the pH value, the number of yeasts, filamentous fungi and clostridia. The L. plantarum reduced
DM losses in silages without calcium oxide, without changing other microbiological and fermentative
parameters. The addition of calcium oxide reduced the neutral detergent fiber (NDF), the concentration
of ethanol and acetic acid and increased the populations of clostridia, filamentous fungi and yeasts.
Calcium oxide lengthened aerobic stability and reduced the temperature during aerobic exposition.
Addition of propionic acid or the strain of L. plantarum was not able to improve the microbiological
quality of the silage treated with calcium oxide. The addition of calcium oxide improved aerobic
stability; however, this addition resulted in lower silage quality observed by higher counts of undesirable micro-organisms.|
