One way to improve rabbit welfare is to enable rabbits to express their natural behaviours. The aim of this study was to investigate the effect of housing and enrichments on behaviour, performance and mortality of growing rabbits (trial 1, n = 294), does and their kits (trial 2, n = 40 females over 2 cycles). The modifications concerned size of housing (length to allow jumping, height to allow standing up), enrichment (gnawing or scratching materials, platform for jumping, burrow for hiding), floor type (wire or plastic mesh) and/or group size. These modifications were implemented separately each other or together. The productive performance of growing rabbits and reproductive does was not influenced by the housing system. In trial 1, behaviours such as standing up, gnawing, jumping and walking were rarely observed (< 5%), but the burrow was frequently occupied (35%). In trial 2, inclusion of gnawing blocks increased gnawing activity. The platform permitted standing and jumping of does, but the proportion of time spent for this activity remained low (0.1%). On the floor, does were more often on plastic-mesh than on wire-mesh (62 vs. 38 % of observations; P < 0.001). The frequency of does on plastic-mesh decreased from 68% the week of parturition to 60% at weaning (P < 0.05), related to increased area occupation by suckling kits (P < 0.001). We confirmed that the enrichments tested allow rabbits to express or increase the frequency of natural behaviour.
