MAFA UNIK – Silo system for outdoor and indoor use

There is nothing more important in animal farming than the structure and quality of the feed. MAFA UNIK is the only feed silo on the market that is specially developed to reduce feed separation and retain feed quality. This is just as important for, so called, environmental feeds as for pellet feedstuffs. The aim is to avoid finer particles increasing towards the end of an emptying cycle.

Silo with mass flow

All the particles flow from the
entire silo area at the same time.

Little separation and best hygiene

Silo with funnel flow

Heavier particles flow out in the middle.
Fine particles stay at the silo walls.

Increased separation and worse hygiene


The diagram above shows the emptying cycle of a pellet feedstuff in a 6 ton silo. At the end of the emptying phase in the funnel fed silo, the percentage of fine particles increased with about 15 %. The MAFA UNIK silo showed a perfect emptying phase. In order to achieve this minimal separation, we have improved the methods of both filling and emptying.


Quality criteria for the feed handling on the farm:

  • Set up your own quality standards for purchased feed.
  • Always take a quality test at delivery, or get one from the feed supplier.
  • Set up goals for hygiene and feed separation.
  • Stipulate which silo fits your demands.
  • Choose a feed auger that retains feed quality.
  • Take regular tests of the feed during feeding and check that the feed retains it´s quality.
