This experiment was designed to study the long-term behavioural effects of gonadal hormone injections into domestic ducklings. Ten male and four female ducklings were injected daily from their 4th day onwards: the males with testosterone propionate and the females with oestradiol benzoate. Five males were injected for 40 days, the other ducklings (5♀ + 4♂) for 80 days. Behavioural effects of these treatments were assessed when the birds were six months old. Social displays were strongly inhibited in the injected males as compared with control birds but no general significant effect was observed for the aggressive and sexual behaviour. The inhibition of social displays is consistent with the view that these behaviour patterns are regulated by the pituitary-gonadal axis and the different levels at which the functional inhibition could have occured are discussed. Far fewer social displays were performed by the males presented with injected females which, on the other hand, showed less sexual behaviour than the control females. This supports the idea that the female plays an important part in the social display of ducks.
本实验旨在研究给雏鸭注射性腺激素的长期行为影响。从第4天起，每天给10只雄性和4只雌性雏鸭注射：雄性注射丙酸睾酮，雌性注射苯甲酸雌二醇。5只雄性注射40天，其他雏鸭（5只♀ + 4只♂）注射80天。当这些雏鸭6个月大时评估这些处理的行为影响。与对照雏鸭相比，注射过的雄性的社会展示行为受到强烈抑制，但在攻击行为和性行为方面未观察到普遍的显著影响。社会展示行为的抑制与这些行为模式受垂体 - 性腺轴调节的观点一致，并讨论了功能抑制可能发生的不同水平。与注射过的雌性共处的雄性进行的社会展示行为要少得多，另一方面，这些雌性表现出的性行为比对照雌性少。这支持了雌性在鸭子的社会展示中起重要作用的观点。
