Big Dutchman builds modern laying system for Spanish egg producer

 
 

Equipment-maker Big Dutchman has helped Grupo Avicola la Cresta, one of the largest Spanish egg producers, build what could be the world's highest egg laying system.

 

The system could handle 150,000 laying hens distributed on seven rows and an impressive twelve tiers with two intermediate ceilings.

 

The Spanish farm was thus able to reach a total bird number of 1 million due to this new arrangment.

 

The new house, the Eurovent EU, is equipped according to the new EU guideline for laying hens valid as of 2012. The farm is located in the town of Sinarcas in Eastern Spain.

 

The new guideline for laying hens, the strict environmental conditions in the area, an unusual size as well as the desire to build the house turn-key caused the project managers to join forces with Big Dutchman.

 

Big Dutchmans' furnished manure belt battery corresponds fully to the new regulations of the EU-directive 1999/74 regarding surface, system height and equipment.

 

The system also features a tailor-made lighting system optimally controlling the daily rhythm of the laying hens: Tube lamps protruding vertically into the aisles at regular intervals ensure a uniform distribution of light.

 

The nest itself is located in the dark so that the laying hens remain undisturbed during egg deposit. A dimmer simulates the different phases of day and is adjusted centrally by means of a sunlight simulator.

 

The system also features the CombiTunnel ventilation which combines two different ventilation systems.

 

At low outside temperatures, ventilation is switched to side mode, creating a stable negative pressure ventilation with very uniform temperatures in the entire house. This is achieved through an intelligent interaction between intake air and exhaust air elements as well as heating systems.

 

When outside temperatures are high, ventilation operates in tunnel mode –providing high air speed and the use of the wind-chill effect to ensure significant cooling with low energy consumption.
