|Abstract: ||The objective of this work was to evaluate the effects of a new strain of Lactobacillus buchneri (UFLA SIL 72) isolated from sugar cane (Saccharum spp.) silage and the addition of propionic acid [1% based on fresh matter (FM)] to silages treated with and without calcium oxide (1% of FM) at 60 and 170 d of ensiling. A randomized block design with a 2 × 2 × 2 × 2 factorial arrangement of treatments was used to analyse the results. The use of calcium oxide reduced the ethanol content and neutral detergent fibre in all silages, increased pH values and favoured the growth of clostridia and yeasts. The addition of propionic acid reduced the yeast population, but it was not able to reduce ethanol content of silage. The addition of L. buchneri resulted in silages with higher concentration of propionate, reduced the levels of ethanol and reduced the population of clostridia in all silages. The use of calcium oxide is not recommended for silage of sugar cane.|
