Management and behaviour of breeding groups of the marsupial Perameles nasuta Geoffroy in captivity

Abstract

The marsupial Perameles nasuta Geoffroy was repeatedly bred in captivity, in large enclosures, for the first time. Methods of management are described. The bandicoot's behaviour was observed on 104 nights with spotlight and binoculars. All the bandicoots used the whole enclosure, were solitary in habit, and were very busy feeders, spending little time in other activities. Sexual activity was restricted to a few nights close to oestrus. Close following of the female by the male led to several matings which occurred in quick succession, with intromission lasting a few seconds. Gestation lasted 12.5 days. The interval between successive periods of oestrus, when young conceived at the first oestrus were successfully reared to weaning, was 62-63 days. Young were carried in the pouch at night for 50-54 days and appeared to be weaned when the next litter was due.
