LOHMANN TIERZUCHT

MANAGEMENT GUIDE

28

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.
