Transfer of thiocyanate into chicken eggs

Laying hens were fed thiocyanate (SCN) as a solution of potassium thiocyanate (KSCN) in their drinking water to determine whether dietary SCN was transferred into eggs. The thiocyanate content of their eggs was measured before and during thiocyanate administration. Egg thiocyanate content increased from 6 micrograms SCN/g albumen to 31 micrograms SCN/g (a 400% increase) in the period immediately following thiocyanate administration and then fell progressively, seeming to stabilize much closer to but still well above control levels.
