Reproduction and post natal development of south african mustelines carnivora mustelidae



Reproduction and post natal development of south african mustelines carnivora mustelidae



Zoologica Africana 13(1): 103-114



Ictonyx striatus and Poecilogale albinucha were bred in captivity. Data indicate a breeding season from the beginning of spring to 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 1-3 for both mustelines. After 20 wk the young of both species were almost fullgrown. Eyes opened at about 40 days (Ictonyx) and about 52 days (Poecilogale). Both species started to eat solids prior to this event. Three juvenile vocalizations were recognized in blind young; thereafter, adult sounds were made. The 1st successful rodent kills were made at 9 and 13 wk by Ictonyx and Poecilogale, 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.
