Environmental Enrichment as Part of the Improvement of the Welfare of Japanese Quails.

The aim of this study was to evaluate the indicators of the behavioural and physiological welfare of Japanese quails () as possible responses to the enrichment of the birds' habitat. The study sample consisted of 280 Japanese quails (224 ♀ and 56 ♂, respectively). Birds of 5 weeks of age were randomly divided into seven equally sized groups and then divided into replication subgroups (four per group, 10 birds in each replication).
