BIOCHEMICAL STUDIES ON VITAMIN METABOLISM IN POULTRY

IV. ON THE URINARY RECOVERY OF THIAMINE IN POULTRY AFTER ADMINISTRATION OF SOME NOVEL THIAMINE DERIVATIVES

抄録

1. Using some thiamine derivatives, iBuTDS, DCET and TTFD, urinary excretion was studied in poultry with an artificial anus.
2. After subcutaneous injection, the urinary excretion was generally greater than after oral administration.
3. Of three non-thiazolium-type thiamine derivatives, iBuTDS and TTFD, continued longer in urinary excretion, whereas DCET administration resulted in less elimination as thiamine in the urine.
