25-Hydroxycholecalciferol levels in camel, sheep and goat.

1. The plasma levels of 25-hydroxycholecalciferol were measured in female dromedary camels, female sheep and Sinai desert goats. 2. The camels had levels of 443 +/- 96 ng/ml in summer, and 267 +/- 113 ng/ml in winter. 3. The sheep had levels of 40.7 +/- 9.09 ng/ml in summer and 37.1 +/- 8.82 ng/ml in winter, i.e. roughly the same as man in that region. 4. The goats had lower levels: 23.9 +/- 5.67 ng/ml in summer.
