Abstract

Ictonyx striatus and Poecilogale albinucha were bred in captivity. Data indicate a breeding season which extends from the beginning of spring to the end of summer. In both species copulation was prolonged. A gestation period of 36 days was recorded for Ictonyx and 32 days for Poecilogale. Litter size was one to three for both mustelines. After 20 weeks the young of both species were almost full grown. Eyes opened at c. 40 days (Ictonyx) and c. 52 days (Poecilogale). Both species started to eat solids prior to this event. Three juvenile vocalizations were recognized to blind young, but thereafter adult sounds were made. The first successful rodent kill was made at nine and 13 weeks by Ictonyx and Poeceilogale respectively, in litters left with their mothers as well as in animals reared in isolation. Play was mainly of an aggressive nature, involving actions typical of adult fighting, prey capture and killing.
