文章综述了25-羟基维生素D3(25-OH D3)在动物(主要是家禽)营养中的研究进展:①25-OH D3改善肉鸡生长性能,但会受到基础饲粮钙、磷和维生素D3(VD3)水平的影响;②25-OH D3改善肉鸡骨骼质量,降低TD(胫骨软骨发育不良)发病率,但受到肉鸡品系的影响;③25-OH D3增加肉鸡植酸磷回肠末端消化率,但未影响肠道(内源)植酸酶活性;④25-OH D3调节肉鸡肠道形态和免疫机能;⑤25-OH D3改善产蛋鸡产蛋后期蛋壳质量;⑥以家禽骨骼和蛋壳质量为评价指标,25-OH D3生物学活性为VD3的1~2.5倍;⑦以家禽肾脏钙化评价,25-OH D3的毒性约为VD3的5~10倍.

Research on 25-hydroxycholecalciferol (25-OH D3) in animal (especially in poultry) nutrition is reviewed. 25-OH D3 improves growth performance of broiler chicks, whereas the re?sponses are influenced by the levels of calcium, phosphorus, and vitamin D3 in basal diets. 25-OH D3 enhances bone quality and decreases TD (tibial dyschondroplasia) incidence, but this ef?fect is influenced by genetic background of birds. 25-OH D3 increases the distal ileum digest?ibility of phytate-phosphorus, but it does not influence the intestinal (endogenous) phytase activ?ities. 25-OH D3 regulates intestine structure and immunity. 25-OH D3 improves egg shell quali?ty in elder laying hens. Bone mineralization and egg shell quality as the criteria, 25-OH D3 is 1 to 2.5 times as effective as vitamin D3. On the basis of renal calcification, 25-OH D3 is 5 to 10 times more toxic than vitamin D3 in poultry.
