Effects of ergosterol on bone mineralisation in chicks given cholecalciferol or ergocalciferol.
Groups of chicks were given diets containing cholecalciferol or ergocalciferol supplemented with 0, 0-1, 1 or 10 g ergosterol/kg. 2. Ergosterol had no significant effect on growth, on the plasma concentration of calcium or on the content of bone-ash, indicating that it did not impair the absorption of either form of vitamin D. 3. An explanation is given for the apparent disagreement in the published findings on the relative anti-rachitic potencies of ergocalciferol and cholecalciferol in the chick.
