“…Moreover, recent data on the concentrations of alpha tocopherol in the organs and tissues of M. brandtii, P. auritus, and E. nilssonii wintering in Karelia show that the level of this vitamin is higher in E. nilssonii, the most winter hardy species (Il'ina et al, 2011). This may be evidence that vitamin supply to bats at the end of hibernation is adequate for coming breeding season.…”

Data of field observations on bats hibernating in the Republic of Karelia (61°-63° N, 30°-36° E) are presented. Various bat winter roosts have been surveyed to reveal the species composition of the animals, the pattern of their spatial arrangement, mortality, and specific regional features and general trends of their hibernation. The results provide a more integrated feature of ecological adaptations of these mammals to the conditions of the North. * Designations: M. br, Myotis brandtii; M. my, Myotis mystacinus; M. br/my, Myotis brandtii/mystacinus; M. da, Myotis daubentonii; P. au, Plecotus auritus, E. ni, Eptesicus nilssonii; ND, not determined. ** One E. nilssonii and two P. auritus bats were recorded in 2002, and two E. nilssonii bats, in 2003 (V.Yu. Kusakina, personal communication).

“…This is probably because the synthetic isomers of all-rac-TOC are accumulated in the liver, owing to the preference of TOC transfer protein (α-TTP) for secreting the natural RRR-stereoisomer of TOC into lipoproteins (30,31) . Il'ina et al (32) found that the TOC concentration was higher in the kidneys than in the liver in both wild and farmed mink. However, the TOC supplementation of the farmed mink in their study was not provided; therefore, the opposite relation between TOC concentrations in the liver and the kidneys in the present study could be a consequence of the dose of TOC supplied in the feed in the two studies, respectively.…”

A sufficient but balanced vitamin supplementation is a prerequisite for a satisfactory growth pattern and an effective immune system in mink and all other species. The fat-soluble vitamins are very sensitive to over-or under-supply because they interact with each other with respect to dose-response and chemical form. The purpose of the present study was to investigate the effect of increasing the amount of retinol in combination with RRR-α-tocopherol or all-rac-α-tocopherol in the feed given to growing mink on their retinol, cholecalciferol and α-tocopherol concentrations in plasma and selected organs. The results showed that the mink met their retinol requirements from the basal diet, but there were no negative effects of supplying various amounts of retinol on their plasma α-tocopherol concentrations. On the other hand, the study showed that the cholecalciferol status in plasma, assessed as the 25-hydroxycholecalciferol concentration, was low when retinol was supplemented in the feed at high levels. In addition, supplementation with RRR-α-tocopherol in the feed negatively affected the plasma concentration of 25-hydroxycholecalciferol compared with supplementation with all-rac-α-tocopherol. In general, female mink had higher concentrations of fat-soluble vitamins in plasma than male mink.
