Nitrogen and energy requirements of the growing brushtail possum Trichosurus vulpecula and the Rex rabbit were studied by means of growth, balance and calorimetry techniques in 2 trials. The maintenance requirements of apparently digestible N were estimated from balance as being 358 and 442 mg/kg0.75 daily for the possums and rabbit, respectively. The standard metabolic rates were 200 and 359 kJ/kg0.75 daily; requirements of apparently digestible energy for maintenance were 370 and 480 kJ/kg daily. The possums grew more slowly over the same weight range as the rabbits and deposited a greater proportion of their gain as fat. At the end of both trials the possums had a greater proportion of carcass fat than the rabbits, and both experimental groups of rabbits and possums were fatter than feral possums of the same weight.

Drug Metabolising Enzymes

Folivore marsupials, such as brushtail possum (Trichosurus Vulpecula) and koala (Phascolarctos cinereus), can metabolise higher levels of dietary terpenes, such as cineole, that are toxic to eutherian mammals. While the highly efficient drug metabolising enzymes, cytochrome P450 3A (CYP3A) and phase II conjugating enzymes (UDP-glucuronosyltransferase, UGT), are involved in the metabolism of high levels of dietary terpenes, evidence for inhibitory actions on these enzymes by these terpenes is scant. Thus, this study investigated the effect of cineole and its derivatives on catalytic activities of hepatic CYP3A and UGT in mice, rats, and possums. Results showed that cineole (up to 50 µM) and its derivatives (up to 25 µM) did not significantly inhibit CYP3A and UGT activities in mice, rats, and possums (both in silico and in vitro). Interestingly, basal hepatic CYP3A catalytic activity in the possums was ~20% lower than that in rats and mice. In contrast, possums had ~2-fold higher UGT catalytic activity when compared to mice and rats. Thus, these basal enzymatic differences may be further exploited in future pest management strategies.
