Vergleich einer neuen Zweinutzungs- mit einer Legehybridebzgl. Tiergerechtheit und Legeleistung

Aim of the study was to compare a new dual purpose hybrid strain (Lohmann dual, LD) with a layer strain (Lohmann Brown plus, LB) under organic conditions. 400 Laying hens were kept in 2 mobile houses (2 x 4 groups of 50 hens). Egg production and egg weight were higher in LBP. LBP hens used the pasture more than LD. However, foraging was the main activity in both strains. LD hens showed less behavioral activity within the hen house. Plumage condition was better in LBP.
