36 LOHMANN TIERZUCHT › MANAGEMENT GUIDE 36 Stocking Density The optimal bird density/m 2 depends on man- agement conditions and to which extent cli- mate can be controlled. 6–8 birds/m² can be taken as a general guide for non-cage hous- ing. For cage systems, an area of at least 475– 540 cm 2 /bird is recommended. Take note of deviating regulations for stocking density and declaration of eggs. Equipment Requirements In general, the more closely the growing house and facilities resemble the future production system, the easier it will be for the pullets to settle down in their new environment after transfer to the laying house. The following tables show the equipment requirements for rearing and production period.
