Reproduction in Antechinus maculatus Gould (Dasyuridae)

The smallest member of the genus Antechinus, A. maculatus has a breeding pattern unlike that of its congeners. Captive females are polyoestrous, and can rear several litters of young each year. Both males and females show an extended breeding season in captivity, and males do not become senile after 12 months of age. Seven litters of A. maculatus, each containing up to 11 young, have been bred; the gestation period is 19-20 days. In comparison with most other marsupials, A. maculatus has a high reproductive potential in captivity.
