“…Bakken, 1976;McNab, 1980;Aschoff, 1981). A comparison of cooling constants between winter-furred raccoon dogs and blue foxes showed that there were no conductance differences between these species (Korhonen et al, 1983a;Korhonen & Harri, 1983). This confirms the idea that body insulation of these species is equivalent.…”

“…Seasonal pelage changes could also influence the metabolic response of the animal to air temperature (T a ) (c.f. Irving et al, 1955;Hart et al, 1965;Korhonen et al, 1983a), thus, having an impact on their energetics.…”

“…Although studies on its energy metabolism (e.g. Makela & Kiiskinen, 1978, 1979Korhonen et al, 1982Korhonen et al, , 1983b) and its thermoregulatory properties (Korhonen et al, 1983a) have been performed, the knowledge of its basic biology is still scarce. For example, few data are available about its moult cycle and seasonal pelage variations (c.f.…”

“…For eutherians, except Me. auratus, published data were used [30][31][32][33][34][35][36]. To compare proton leak rates of liver mitochondria between different groups, the proton leak values of marsupial species are shown at their respective physiological body temperature but were also extrapolated to 378C.…”

Phylogenetic differences of mammalian basal metabolic rate are not explained by mitochondrial basal proton leak

et al. 2011

Metabolic rates of mammals presumably increased during the evolution of endothermy, but molecular and cellular mechanisms underlying basal metabolic rate (BMR) are still not understood. It has been established that mitochondrial basal proton leak contributes significantly to BMR. Comparative studies among a diversity of eutherian mammals showed that BMR correlates with body mass and proton leak. Here, we studied BMR and mitochondrial basal proton leak in liver of various marsupial species. Surprisingly, we found that the mitochondrial proton leak was greater in marsupials than in eutherians, although marsupials have lower BMRs. To verify our finding, we kept similar-sized individuals of a marsupial opossum (Monodelphis domestica) and a eutherian rodent (Mesocricetus auratus) species under identical conditions, and directly compared BMR and basal proton leak. We confirmed an approximately 40 per cent lower mass specific BMR in the opossum although its proton leak was significantly higher (approx. 60%). We demonstrate that the increase in BMR during eutherian evolution is not based on a general increase in the mitochondrial proton leak, although there is a similar allometric relationship of proton leak and BMR within mammalian groups. The difference in proton leak between endothermic groups may assist in elucidating distinct metabolic and habitat requirements that have evolved during mammalian divergence.

“…Due to a high surface-to-mass ratio, it has to sustain higher basal metabolic rate than other mammals of the same body weight [13] [14]. This may set special demands for its energy metabolism and feeding [15]. Metabolic effects of carotenoids are promising [3].…”

The present study sought to find out how carotenoid supplement influences on body weights, feed consumption and reproductive success in standard farm mink (Neovison vison). Carotenoids were from microalgae Haematococcus pluvialis. A dose of carotenoid supplement of 0.20, 0.25, 0.20, 0.20, and 0.10 g/animal was added daily in feed in February, March, April, May and June, respectively. Experimental groups were: 1) control group, and 2) carotenoid group. Each group comprised 100 females and 25 males. The results showed that appetite of animals in all groups was good. Significant differences were not found in body weights before breeding. However, weights of control females were significantly (P < 0.05) lower compared with those of carotenoid fed animals when kits aged 21 days. At the age of 21 and 42 days, body weights of kits were similar in both groups. However, kits from carotenoid group tended to grow better (P < 0.1) than those from control group. Number of whelped females was lower in control group (81 vs 85 females). Number of barren females was higher in control than in carotenoid group (16 vs 13 females). Significant differences were not found in number of kits per mated and whelped female. Number of lost kits was higher in the control group at the age of 21 days (24 vs 20 kits) and the age of 42 days (40 vs 26 kits). The present study showed that carotenoid supplement could be used in mink diet. The results are promising, but require further studies before final implementation.
