Seasonal reproduction in the ewe is generated by an endogenous circannual rhythm of reproductive neuroendocrine activity. Exposure to as few as 70 days of photoperiodic information a year is sufficient to synchronize the rhythm. The present study was

Although many species display endogenous circannual rhythms of biological activity that are synchronized by day length, the specific photoperiodic requirements for synchronizing such rhythms are not established for any species. We tested the hypothes

Circulating patterns of luteinizing hormone (LH) and prolactin (PRL) were monitored for 5 yr in ewes maintained either outdoors in natural conditions or indoors in a fixed, short photoperiod (8L:16D). The ewes were ovariectomized and each was treated
