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.
