Honess, P., Andrianjazalahatra, T., Fernandez, L. et al. 2012. Environmental enrichment and the behavioural needs of macaques housed in large social groups. Enrichment Record 10, 16-20.

In this article, we address some of the issues surrounding the behavioural needs of captive animals and go on to elucidate some of the key aspects of the environmental enrichment strategy at Bioculture (Mauritius) (BCM) designed to balance safety, animal welfare and the practicalities of meeting the appropriate behavioural needs of over 22,000 group-housed long-tailed macaques (Macaca fascicularis). ... Putting the animals' needs (and reasonable safety) at the centre of our enrichment strategies will not only help meet ethical commitments but will also, through reduced stress, improve research model quality and help convince an often sceptical public that we in the research sector are truly committed to the highest standards of animal welfare.
