Blood samples, behavior, food consumption, body mass, and cloacal gland sizes were collected from the birds throughout the next 12 experimental days that passed. The results indicate that the exogenous testosterone administered to Japanese quail did not elevate circulating hormone levels.26enJapanese quailExogenous tesosteroneCoturnix japonicapolymer microspheresBehaviorMorphologyPhysiologyDEENK Témalista::Biológiai tudományok
