The Use of 25-hydroxy Vitamin D3 for Meat Poultry
نویسنده
چکیده
Over a period of time, two vitamin D parent compounds were elucidated. Ergocalciferol (D2) is synthesized from ergosterol in many plants, whereas cholecalciferol (D3) is derived from 7-dehydrocholesterol in the skin of animals. Ultraviolet light transforms these compounds into 1, 25-diOH vitamin D3, the vitamin D metabolite generally considered the most active. Approximately 40 times more D2 is needed to equal D3 for poultry.
