How to Achieve...


Spoilage may cause huge energy losses, emphasizing the importance of reducing it to a minimum. But where to start?

Silage Clamps

Effective and regular compaction of the clamp is crucial as air must be removed from the forage. Only under anaerobic conditions can lactic fermentation run off undisturbed, and putrefactive bacteria, yeasts, moulds and reheating can be avoided.

The rolling weight of the compaction vehicles must be adjusted in relation to the harvest chain. With high out-put chains, it may be necessary to use more compaction vehicles on the clamp or even to fill two clamps simultaneously. A guideline for grass silage making limits the harvesting performance per compaction vehicle to 15-20 t DM/hour.(13)

Distribution and rolling are other key points. The forage brought into the clamp should be distributed in layers of maximum thickness 30 cm and compacted with a driving speed of approximately 4-6 kph in order to achieve sufficiently high bulk densities of at least 200 kg DM/m³.(14, 15)

To avoid air and moisture, it is important to ensure a short harvest without long filling times for the clamp as well as timely and proper coverage of the clamp. Sufficient levelling and inclination of the forage also plays a significant role. This will ensure that rainwater can easily flow off the surface of the clamp.

To limit possible air penetration when feeding out, and thus to reduce heat generation, a smooth cut face is required combined with a feed rate of at least 1.5 m per week in the winter and 2.5 m per week in summer.(16)

Baled Silage

In general the same requirements apply for baled silage as for clamped silage.

The most critical factor is to achieve high bale density, however proper wrapping of the bales is also important so as to eliminate presence of oxygen and therefore danger of spoilage.
