本研究以 L-維生素 C (AA)、L-ascorbic acid-2-sulfate (AS) 及Polyphosphorylated L-ascorbic acid (APP) 等來作為黑鯛飼料中維生素 C來源,進行為期八週的蓄養試驗。結果顯示,AA、AS 或 APP 均具有抗壞血病的活性。餵飼缺乏維生素 C的黑鯛會顯現出眼框中出血、腹水腫、眼睛外凸、脊椎彎曲及肝臟和血液中維生素 C 的蓄積量降低等症狀。以APP餵飼的黑鯛肝臟中維生素 C 蓄積量顯著高於餵飼 AA 或 AS,顯示了黑鯛對 APP 的利用性高於 AS,且黑鯛能利用 APP 作為維生素 C 優質來原.

摘要abstract(英)


Purified diets were formulated and fed to four groups of black porgy Acanthopagrus schlegeli fingerlings for 8 weeks. L-ascorbic acid (AA),L-ascorbic acid-2-sulfate (AS) or L-ascorbic acid-2-polyphosphate (APP) weresupplemented to the test diets at 100 mg/kg diet ascorbic acid equivalence. Thecontrol diet was ascorbic acid-free. The result indicated that APP, AS or AA hadantiscorbutic activities. There were no gross signs of vitamin C deficiency inany of the fish fed AA, AS or APP, where as hemorrhagic exophthalmia, ascites,fin hemorrhages, spinal curvature and reduced concentrations of ascorbic acid inblood and liver were found in the control group. Ascorbic acid content washighest in the liver of the porgy fed APP diet. This result indicates that APPhas equimolar activity to L-ascorbic acid as a vitamin C source for black porgy.
