Abstract
Captive breeding and reintroduction programs are making a significant contribution to the survival of several endangered species. We demonstrated that the numbat (Myrmecobius fasciatus) can be maintained within a captive breeding program at Perth Zoo, Australia, for the purposes of release. We found that females have one litter per year but can be mated two or three times in the breeding season if they fail to conceive or lose their young. The mean (±s.e.m.) interval between mating in polyoestrous females is 25.2 ± 1.6 days. Males show spermatorrhoea with development of secondary sexual characteristics in the breeding season between November and late February.
Additional keywords: male, mating.
Acknowledgements
The authors acknowledge the invaluable contributions of all those that made the breeding program possible, notably Dr Tony Friend, Dr Mark Bradley, Dr Helen Robertson and all the keeping and veterinary staff over the years at Perth Zoo. The help and support of Caroline Lawrence has been invaluable. Dr Brenton Clarke (School of Chemical and Mathematical Science, Murdoch University, Western Australia) kindly advised on the use of the Wald–Wolfowitz runs test. Thank you all.
