Recently the metabolic cost of swinging the limbs has been found to be much greater than previously thought, raising the possibility that limb rotational inertia influences the energetics of locomotion. Larger mammals have a lower mass-specific cost of transport than smaller mammals. The scaling of the mass-specific cost of transport is partly explained by(More)
The study investigated the effect of a slow-release formulation of zuclopenthixol acetate (Acunil®) on blue wildebeest ( Connochaetes taurinus ) in captivity. Two groups of trials were conducted using either Acunil or a placebo (control). Animals (Acunil: n = 17; placebo: n = 12) were observed for a 12-hr period before the administration of Acunil or the(More)
Differences in limb size and shape are fundamental to mammalian morphological diversity; however, their relevance to locomotor costs has long been subject to debate. In particular, it remains unknown if scale effects in whole limb morphology could partially underlie decreasing mass-specific locomotor costs with increasing limb length. Whole fore- and(More)
In order to alleviate the current food security situation the world is faced with, it is essential to investigate meat sources which have the potential to be used in a sustainable manner. This review provides substantial arguments to prove the viability of sport hunted wildfowl as a food source in Southern Africa. However, before the use of wildfowl meat(More)
Cold-shortening is the response when muscles are exposed to temperatures below 10°C with a pH>6.20. The course of pH within hot-deboned and intact ostrich M. gastrocnemius, pars interna and M. iliofibularis were followed for the first 23-24h post-mortem to investigate the changes in pH as well as to determine the point of minimum pH for ostrich muscles(More)
