摘　　要：25-OH-D3是维生素D3在动物体血液中的主要存在形式,且25-OH-D3在动物体内活性比维生素D3更高,肉仔鸡日粮中25-OH-D3的生物学效价比维生素D3高,吸收更有效。因此,在肉鸡饲养中合理添加25-OH-D3,这对于肉鸡的骨骼、生长性能、加工性能等会造成有益的影响。25-OH-D3 is the main form of vitamin D3 in animal blood,and the activity of 25-OH-D3 is higher than that of vitamin D3 in animal blood.The biological potency of 25-OH-D3 in broiler diet is higher than that of vitamin D3,and the absorption of 25-OH-D3 is more effective.The reasonable addition of 25-OH-D3 in broiler diet has a beneficial effect on the bone,growth performance and processing performance of broiler.
