Whole-plant silage (WPS) is a mixture of straw, grains or kernels that is quite susceptible to reheating. Appropriate silage management therefore plays a decisive role, both when harvesting and during the ensiling process. Our service identifies all essential management factors for producing high-quality WPS silage.
The optimal harvesting time is between late milky ripeness and early waxy ripeness
Caution: Note the pre-harvest interval for feed use after applying crop protection products.
Cutting heights of 20–40 cm have proven effective for creating a grain/straw ratio of 1:1. Higher cuts may be used to increase the energy content in silage. However, this will be at the expense of mass yield.
The optimal chop length is 6 to a maximum of 8 mm. Otherwise good compaction cannot be ensured. Stems and stem nodes must be split open; otherwise their tubular structure prevents adequate compaction and ensiling.
The tubular stem structure creates a loose mass inside the silo that promotes the circulation of air. As a result, the risk of reheating due to moulds increases. Cereal GPS is additionally low in nitrate and therefore susceptible to the formation of butyric acid. BONSILAGE silage additives reliably produce aerobically stable WPS silages.
The effect of BONSILAGE silage additives depends on precise application rates, among others, as these are decisive if lactic acid bacteria preparations are to be optimally effective. SCHAUMANN dosing technology is tailored to BONSILAGE products.
Optimal compaction of WPS silages helps prevent reheating. Ideally, compaction results in at least 230 kg DM/m³ if the base substrate has a dry matter content of 35%. At 45% DM, compaction should aim at a minimum of 260 kg DM/m³.
Measures for optimal compaction:
For optimal silage wrapping:
WPS silages are highly susceptible to reheating, which causes expensive nutrient losses. The minimum removal rate should be 2 m to avoid this.
