An immunological assessment of group-housed rabbits.
Laboratory rabbits kept in barren 'traditional' cages tend to develop stereotypic behaviours and bone deformities. We have used an alternative regime, housing adult does as groups of four or five in floor pens (2.5-3 m2) supplied with hiding places and bedding. High- and low-ranking members of each group were identified, and their immunological status compared in terms of blood leucocyte function (chemiluminescence and mitogen tests), complement activity, and antibody production to soluble and cellular antigens. We found no evidence of immunosuppression, either in groups of a 'docile' breed (New Zealand White) or Dutch crosses. These results, together with the animals' general health and ease of handling, lead us to conclude that group-housed does are suitable for raising antisera and other purposes, provided that they are adequately monitored.
