摘要
文章综述了25-羟基维生素D3（25-OHD，）在动物（主要是家禽）营养中的研究进展：①25-OHD3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-OHD3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-OHD3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-OHD3 调节肉鸡肠道形态和免疫机能；⑤25-OHD3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-OHD3生物学活性为VD，的1-2．5倍；⑦以家禽肾脏钙化评价，25-OHD3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. 25-0H 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 dysehondroplasia） incidence, but this ef- fect is influenced by genetic background of birds. 25-0H D3increases the distal ileum digest- ibility of phytate-phospborus, 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 anti 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.
