Vitamin D2 (Ergocalciferol), drived from plant sources or dietary supplements, could be used as supplement of Vitamin D[1][2].

IC50 & Target

Human Endogenous Metabolite


In Vivo

At sacrifice, after 5 weeks of treatment, chickens receiving omeprazole alone or omeprazole in combination with either restricted food intake or Ergocalciferol weighed 15-25% less (P < 0.01) than chickens given vehicle or receiving reduced amount of food[2].
Combined treatments of fasting and ergocalciferol show more deleterious effects on growth than fasting only or ergocalciferol only and induced face anomalies[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 83 chickens (White Leghorn), weighing 318 ± 9 g[2].
Dosage: 250,000 IU/kg
Administration: S.C. once daily.
Result: Induced a long-lasting hypercalcemia in rat and mice and suppresses the expression of PTH mRNA in the rat.
