Requirements for the welfare of baboons and pigs used in animal-to-animal xenotransplantation experiments.
OBJECTIVE
Review the welfare requirements of pigs and baboons used for xenotransplantation in research laboratories. Because of the requirements to maintain optimum health status, these animals are often kept in barren enclosures with little or no enrichment. They may also be exposed to procedures causing stress and discomfort. Although animal-to-human xenotransplantation is, at the present time, not approved in Australia, research is currently being performed to develop laboratory procedures, using the pig-to-baboon model.


CONCLUSIONS
We make recommendations for the husbandry of baboons and pigs used for xenotransplantation, to increase their welfare and minimise stress during experimental procedures, while attempting to preserve the health status required. It is proposed that novel standards should be devised and implemented for baboons, whereas existing pig welfare appraisal schemes could, with minor changes, be suitable for assessing the welfare of pigs used for xenotransplantation.
