Irregular ovarian activity, body condition and behavioural differences are associated with reproductive success in female eastern black rhinoceros ( Diceros bicornis michaeli )

Highlights • Intrinsic differences exist between parous and nulliparous black rhinoceros females. • Nulliparous females exhibit more irregular oestrous cycles, particularly >40 days. • Nulliparous females also exhibit fewer overt behavioural signs of oestrus. • Unpredictable females have higher g...

Description
Summary:Highlights • Intrinsic differences exist between parous and nulliparous black rhinoceros females. • Nulliparous females exhibit more irregular oestrous cycles, particularly >40 days. • Nulliparous females also exhibit fewer overt behavioural signs of oestrus. • Unpredictable females have higher glucocorticoids and are less likely to have bred. • Nulliparous females also had higher body condition scores than parous females.
