Abstract

The aim of the present study was to clarify the relation between salsolinol (SAL)-induced prolactin (PRL) release and photoperiod in goats. A single intravenous (i.v.) injection of SAL was given to adult female goats under short (8h light, 16h dark) or long (16h light, 8h dark) photoperiod conditions at two different ambient temperatures (20°C or 5°C), and the PRL-releasing response to SAL was compared to that of thyrotropin-releasing hormone (TRH) or a dopamine (DA) receptor antagonist, sulpiride. SAL, as well as TRH or sulpiride, stimulated the release of PRL promptly after each injection in both 8- and 16-h daily photoperiods at 20°C (P
