Extract

1. A condition that appears to be identical with ‘green yolks’ as observed in natural cases has been reproduced by the oral administration in gelatin capsule of from 250 to 1000 mg. sodium copper chlorophyllin 100% daily for 4 days upwards to Light Sussex hens in second lay.

2. Following suitable extraction procedures the presence of a chlorophyll derivative has been determined spectrophotometrically in the affected yolks.

3. Quantities of sodium copper chlorophyllin of the order of 1 mg. have been recovered from affected yolks.

4. It is considered that the passage of chlorophyll to the yolk indicates that intestinal absorption has occurred.
