New technology: Claas buys maize chop technology

How maize silage looks after the Shredlage treatment.

Claas has acquired the Shredlage technology, patented by the US company of the same name.

Claas had the new MCC (Multi Crop Cracker) Shredlage crop processor for the Jaguar 900 range on display at the Lamma show in England last January, with the claim it could increase milk yield as much as two litres per cow.

The technology is a form of maize silage treatment used by increasing numbers of dairy cattle farmers in regions lacking in grassland.

It involves chopping the maize into unusually long sections of 26mm to 30mm.

Downstream treatment using the Shredlage cracker technology is key to the entire process.

The intensive conditioning of the material enlarges the surface area of the chopped product, in order to significantly improve bacterial fermentation after ensiling, and above all, during digestion in the cow’s rumen.

The aim is to substantially increase the structural effects of maize silage in the rumen, while adding to the availability of the starch contained in all plant parts.

This could lead to an increase in milk yields.

In addition, the rumen-friendly silage structure is believed to improve the health of the herd, and could allow reduced use of concentrate feed. The need to supplement with fibrous fodder such as straw can be reduced or even eliminated.

The new MCC Shredlage crop processor at Lamma had specially designed teeth, and two LorenCut rollers had a counter-rotating spiral groove, so that as the crop passes through the rollers, it was pulled apart sideways.

As a result, the stalks are shredded and the bark peeled off, to increase the surface area of the chopped crop.

Studies in the US and Germany indicate that by increasing the availability of starch from all parts of the plant with this process, milk yields and growth rates are increased, silage intake is higher, the lactation curve is flatter, and overall herd health improved.

“We are convinced that Shredlage delivers a clear benefit to the customer. By taking over this well-known brand, we are now adding the finishing touches to our technology concept as international market leaders for self-propelled forage harvesters”, explained Hermann Lohbeck, responsible for the forage harvesting division on the Claas executive board.

“We are thrilled that the inventors of the technology used as part of the Shredlage brand, Ross Dale and Roger Olson, will remain on board to advise us and our customers”,
