Effects of harvest year and scaling-down on changes inmaize silage microbiome during ensiling
Keywords:
bale silo, microsilo, microbiome, vintage, downscalingAbstract
In 2017, a bale silo (800 kg) and 8 microsilos (200 litres), and in 2018, 8 silos were filled with chopped full corn, and the changes in the numbers of total bacteria, lactic acid bacteria, moulds and yeasts, the major microbial groups involved in ensiling, were determined from 0 to 150 days. Our aim was to demonstrate that the 200-litre microsilos created for maize silage experiments are suitable for modelling the microbiological processes that take place during the silage process in large silos such as a bale silo. With our results we proved that in the case of the experimental microsilos the smaller size did not affect the microbiological processes taking place during silage period, changes in the microbiome composition properly models the original, much larger silos, their use is suitable for further starter culture research.
