Single intrauterine injection of prostaglandins E1, E2, and F2α induced premature oviposition in the turkey within a few minutes. Indomethacin (50 mg/bird) blocked spontaneous oviposition by several hours. Plasma levels of both PGE and PGF increased significantly around the time of oviposition and appeared not to be related to increasing levels of either progesterone or LH during the ovulation cycle. These data are consistent with the proposed physiological role for prostaglandins in the regulation of avian oviposition.
