Abstract
1. Pregnenolone, progesterone, deoxycorticosterone and cortico‐sterone were injected into hens between 16.30 and 17.00 h on the day of oviposition of the last egg of a sequence. 2. Pregnenolone did not affect ovulation, but all of the other steroids induced ovulation prematurely. 3. To induce premature ovulation in 50% of the hens, 82–31 μg± 0.06 μg, 23–86 μg±0.07 μg and 659–26 μg + 0.05 μg of progesterone, deoxycorticosterone and corticosterone, respectively were required for injection. 4. Differences were observed in the times of oviposition of eggs which ovulated in response to injections of either progesterone or a corticosteroid and it was suggested that the mechanism of action of progesterone and corticosteroids operates through different endocrine pathways.Keywords
