Determination of vitamins D, A, and E in sera and vitamin D in milk from captive and free-ranging polar bears (Ursus maritimus), and 7-dehydrocholesterol levels in skin from captive polar bears

Determination of vitamins D, A, and E in sera and vitamin D in milk from captive and free-ranging polar bears (Ursus maritimus), and 7-dehydrocholesterol levels in skin from captive polar bears

The difference between serum levels from 36 captive and 56 free‐ranging polar bears (Ursus maritimus) for 25‐hydroxyvitamin D (25‐OH‐D) was found not to be significant (mean ± SD = 348 ± 215 nmol/L [captive], 360 ± 135 nmol/L [free‐ranging], t = 0.30, df = 52.8, P = 0.76), whereas the difference for...
