Br. Blakley et al., Trace mineral and vitamin concentrations in the liver and serum of wild muskoxen from Victoria Island, J WILDL DIS, 36(2), 2000, pp. 301-307
Selected trace minerals and vitamins were assayed in the liver and serum of
25 wild muskoxen (Ovibos moschatus) from Victoria Island, (Nunavut, Canada
) in November, 1995. Mean +/- SE liver concentrations in mu mol/kg wet weig
ht were 260 +/- 16 for copper; 1.04 +/- 0.06 for selenium; 11.5 +/- 0.7 for
molybdenum and 62.8 +/- 3.3 for vitamin E. Mean +/- SE serum concentration
s in mu mol/L were 14.2 +/- 0.3 for copper; 0.75 +/- 0.04 for selenium, 1.5
3 +/- 0.07 for vitamin A and 5.80 +/- 0.55 for vitamin E. Comparison of liv
er and serum concentrations of copper, selenium and vitamin E showed that t
he concentration in one tissue was a relatively poor indicator of the conce
ntration in the other. The copper-molybdenum interaction often seen in dome
stic species was not observed. In general, the concentrations of metals and
vitamins found in muskoxen were comparable to those in other ungulates alt
hough serum vitamin E concentrations were about one-fourth of those expecte
d.
