Measurement of 25-Hydroxycholecalciferol in the Bovine
Journal of Dairy Science, 1976 Bovine plasma 25-hydroxycholecalciferol was estimated by rapid protein binding assay. Serum-binding proteins in the assay were from rats deficient in vitamin D and from normal rats; no differences existed in standard curves. Nanograms 25-hydroxycholecalciferol in eight cows averaged 45.5 +/- 12.2 ml of plasma.
