Abstract
SummaryFree thiamine concentrations in yolk decreased from 3 to .4 ppm when adult White Leghorn females were fed .2% amprolium. The lowest free vitamin concentration in yolk was reached by day 11 on medication, but maximum effect on the hatch did not occur until the 3rd week on medicated diets. On withdrawal of medication, free thiamine in yolk returned to original concentration in 6 days while normal hatches were obtained in 3 days. Minimum free thiamine in yolk for optimum hatch was found to be about .63 ppm.
