The enriched colony system for layers.

With the EUROVENT EU colony system, Big Dutchman provides you with everything you need for animal-friendly and efficient egg production. Two of the most important advantages are maximum hygiene and the best possible product safety. 

This means the system meets the following requirements:

  • at least 750 cm2 colony surface area per hen with 600 cm2 usable area
  • the total colony surface area must be no less than 2000 cm2
  • colony height no less than 45 cm
  • no less than 12 cm trough length per hen
  • every hen must have access to at least two nipple drinkers;
  • nest and litter bath must be available
  • every compartment must be equipped with a claw-shortening device;
  • the floor slope must not exceed 14 % or 8°
  • aisle width of no less than 90 cm
  • minimum distance of 35 cm between barn floor and bottom tier

Main advantages

  • mature technology
  • high laying performance
  • clean eggs
  • minimum share of cracked eggs (115 mm egg belt width)  
  • healthy hens 
  • low mortality rate
  • good feed conversion
  • high functional reliability of all supply and removal systems (feed, water, egg belts, litter, manure removal);
  • the entire colony front consists of sliding grids that can easily be opened to move the hens in an animal-friendly way
  • all wire grilles are zinc-aluminium coated for high corrosion protection
  • the bottom wire grille has a mesh size of 1 x 1.5 and a slope of only 12 % or 7° and rests on tension wires, which ensures excellent egg quality
  • manure belt ventilation (optional) makes for optimal manure drying that keeps ammonia emissions in the barn to a minimum and produces spreadable and storage-stable dry manure.
