Free range and organic systems provide different circumstances for laying hens than closed houses or cages, where most hens are selected in. An enquiry and farm visits were done in The Netherlands, Switzerland and France in order to find out what gen

Since 1960 the majority of commercial layers are housed in cages. Non-cage housing started to appear again from 1980 onwards and increases in importance. It is questionable if birds bred to perform in cages are also suited for free range housing. We

Bei der Freilandhaltung von Geflügel kommt es immer wieder zu Neuansteckungen mit Parasiten. Ziel kann daher kaum deren vollständige Ausrottung sein. Vielmehr geht es um die Begrenzung auf ein für Tier und Mensch erträgliches Mass. Beim Huhn sind

Organic poultry production has substantially increased in the last few years. On organic farms, welfare of poultry is enhanced due to enriched housing conditions as access to a free range area. This may reduce feather pecking and keep the health stat

In order to test the effect of organic vs. conventional diets on fertility traits, we conducted an on-farm study with female rabbits. Eight groups of seven to eight female rabbits kept in systems with litter were fed ad libitum with either organic or

In der Kaninchenhaltung unter den Bedingungen des ökologischen Landbaus ist der Einsatz von Kokzidiostatika nicht erlaubt. Wie sich Kokzidiose, aber auch andere Darmerkrankungen und die damit verbundenen Verluste dennoch eindämmen lassen, wurde in
