CAGE HOUSING

25 LOHMANN TIERZUCHT › MANAGEMENT GUIDE 25 This programme can be used for up to 7 or 10 days after arrival, then switch to the regular step down lighting programme. The usage of the following lighting program brings about the following advantages: › The chicks will rest and/or sleep at the same time. This means that the behaviour of the chicks will be synchronized. › Weak chicks will be stimulated by stronger ones to move as well as to eat and drink. › The behaviour of the flock is more uniform and the judgement of the birds is made easier. › Mortality will decrease. To which extent lighting hours are reduced during the growing period and the time when stimulation begins by increasing the lighting hours are means by which perfor- mance can be adjusted to specific farm re- quirements. The following Standard Lighting Programme is designed as an example for a quick start into production. The light intensity measured in watt/m², lumen, foot candle or lux depends on the used light source. Giving advices concerning this measurement would rather irritate than help layer farmers. Therefore the light intensity is just given in lux unit in the following table.  Lighting Programme for  Windowless Houses  for Pullet/Layers LOHMANN BROWN Layer LOHMANN LSL Layer 2h 2h 2h 2h 4h 4h 4h 4h darkness light Lighting Programme after Arrival Lighting Programme for Closed Houses LIGHTING
