The ARC has recently approved a new Policy on Breeding Colony Management; the updated Policy is available at the Breeding Colony Management web page. This Policy provides important information about minimum space requirements, harem breeding, and extended weaning periods, and supersedes the long-standing ARC Policy on Extended Weaning Periods.
