Abstract
Mature, regularly laying domestic hens were hypophysectomized at intervals ranging from 10 hrs. to 2 hrs. before an expected ovulation. The expected ovulation in 119 cases was that of an initial member of a clutch, and in 41 cases was that of an intraclutch or terminal member. The percentage of birds ovulating the expected ovum increased with the decrease in interval from hypophysectomy to actual or expected ovulation, and the most frequent interval between apparent release and ovulation was of the order of 4-6 hrs. and was not related to position in the clutch.Keywords
