Birth seasonality in captive bovids at Al Wabra Wildlife Preservation (AWWP), Qatar


Piening Schuler, Y; Hammer, C; Clauss, Marcus; Hammer, S (2009). Birth seasonality in captive bovids at Al Wabra Wildlife Preservation (AWWP), Qatar. In: Wibbelt, G; Kretzschmar, P; Hofer, H. Proceedings of the International Conference on Diseases of Zoo and Wild Animals. Berlin: Leibniz Institute for Zoo and Wildlife Research, 297-303.

Abstract

Twenty six African and/or Asian bovid species kept at Al Wabra Wildlife Preservation, Qatar
(latitude 25 °N, longitude 51 °E, altitude < 100m above sea level) were evaluated for their birth
seasonality. A broad range of breeding patterns could be observed, from breeding throughout the
whole year (e.g. blackbuck, dorcas gazelle, idmi gazelle, Speke´s gazelle), to explicit seasonality
(e.g. mouflon, nilgai, Nubian ibex, wild goat) in breeding patterns. In general, natural breeding
patterns were preserved in captivity. In some species, deviations from patterns reported in the
wild are evident, with longer birthing seasons in captivity, sometimes with calves being born the
whole year round. This applies mainly for species where birthing correlates with the rainfall
season in the wild (e.g. beira antelope, idmi gazelle). It can be speculated that when water, and
subsequently food, is supplied constantly, breeding is no longer seasonally restricted, indicating
that the respective species are mainly resource-controlled in their reproduction. In species in
which reproductive seasonality is preserved in captivity, day length itself is speculated to trigger
oestrus activity (e.g. wild goat, Nubian ibex).
