Exogenous melatonin does not influence photorefractoriness in the testes of roseringed parakeet, Psittacula krameri (Neumann)



Exogenous melatonin does not influence photorefractoriness in the testes of roseringed parakeet, Psittacula krameri (Neumann)



Pavo 33(1-2): 5-9



The question whether exogenous melatonin influence the photorefractoriness of testes in the Roseringed Parakeets was addressed in the present investigation. The birds were held under natural photoperiods, or under artificial long (16L 8D) or short (8L 16D) daily photoperiods for 45 days and were subsequently administered daily during the afternoon with melatonin at a dosage regimen of 20 mu-g/100 g body wt for 10 consecutive days.
