Body mass development and survival rate in hand - and parentreared bovidae at Al Wabra Wildlife Preservation (AWWP), Qatar


Piening Schuler, Y; Hammer, C; Hammer, S (2009). Body mass development and survival rate in hand - and parentreared bovidae 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, 291-296.

Abstract

Several bovid species kept at Al Wabra Wildlife Preservation were evaluated for neonatal body
mass development as well as their survival rate. Of special interest was the comparison of these
parameters between hand- and parent-reared animals. For body mass development, a general
pattern could be found, showing weight development stagnation shortly after birth, followed by
linear growth. Post natal body mass of parent-reared animals and its development was in all 3
compared species found to be above hand-reared animals. Hand-rearing might be an effect of,
not the reason behind this phenomenon. Survival rates in hand-reared individuals were higher
than in parent-reared, not only as neonates but also as adults. Especially Beira antelopes
(Dorcatragus megalotis) and Speke´s gazelles (Gazella spekei) profited from hand-rearing,
whereas the effect on Gerenuks (Litocranius walleri) and Phillip´s dikdiks (Madoqua saltiana
phillipsi) was smaller. It might be concluded, hand-rearing in populations with a critical health
status being a protective measure that increases the survival of offspring. In species with less
disease problems, handrearing may be less decisive for increasing offspring survival.
