Abstract/Summary

-
On the one hand, the greater kudu (Tragelaphus strepsiceros) is a strict browser and would therefore be expected to display a ‘moose-type’ digestive physiology with a comparatively low rumen fluid throughput, a low ratio of small particle to fluid mean retention time (MRT) in the reticulorumen (RR), and relatively unstratified RR contents. On the other hand, reports on relatively small salivary glands, susceptibility to negative effects of tannins, and a putative absence of tannin-binding salivary proteins would suggest the greater kudu to be an exceptional browser with a ‘cattle-type’ digestive physiology. We measured MRT in four zoo-kept greater kudu females, which resulted in a MRTparticleRR/MRTfluidRR ratio between 1.07–1.43, well within the range of ‘moose-type’ ruminants and similar to eland (Taurotragus oryx). In this regard, consistent morphophysiological studies on greater kudu are required to resolve the seemingly contradictory findings in this species.
