Chopped maize is one of the most common types of silage
Making silage is a natural, sustainable process. Silage is naturally preserved green fodder that can be fed to livestock in winter. Chopped maize is one of the most common types of silage, together with grass silage. Maize is easy to preserve. It contains less protein and more sugars than grass.
When maize is chopped and ensiled, various factors have to be taken into account. Getting the harvest time and dry matter right and preventing fermentation are very important for high-quality silage. Once fermentation occurs in the pit, it’s difficult to get rid of it. Fermentation causes valuable nutrients to be lost, and results in lower absorption by livestock.
After maize has been chopped, it is ensiled in a silage heap or a silage bunker. This is done with a maize leveller in equal and thin layers. The maize is compressed with a Holaras Stego silage packer, making the silage becomes depleted of oxygen as quickly as possible. Maize is usually chopped by a harvester/chopping machinery working in tandem. The maize is therefore loaded on the silage more frequently, so it’s important that the speed of spreading is in line with this frequency.
High-energy maize for biogas installations
High-energy maize is usually grown exclusively for fermentation in biogas installations. In Germany, legislation (the EEG or Erneuerbare Energien Gesetz) has stimulated an enormous expansion of the biogas sector, which now has some 8,000 installations, mostly on farms. These installations run almost exclusively on manure and maize. Maize can be used to generate energy in various ways: via fermentation, via co-fermentation, and as a basis for ethanol. When used for ethanol production, 3.2 tonnes of dry matter of maize is converted into 1 tonne of ethanol. The potential yield of maize per hectare is high, and maize is easy to silage.
