Analysis of reproductive behavior in male pigeons in the White Mirthys and Egyptian Baladi breeds injected with testosterone propionate.

Studied

Randomized animal experiment comparing testosterone propionate injections in male pigeons with vehicle injections.

Who / model

White Mirthys and Egyptian Baladi pigeons, with 27 adult pairs per breed. The abstract does not state the overall study duration.

Studied dose & schedule

Dose and schedule have not yet been extracted for this summary.

Found

Testosterone increased circulating testosterone and aggression, while parental feeding fell to nearly zero. Offspring mortality was higher in White Mirthys, especially at the higher dose, but remained unchanged in Baladi. The interval between hatching and laying shortened only in the higher-dose Baladi group.

Limits

Study limitations were not stated in the abstract. Methodological quality has not been appraised.
