Dopamine and prolactin involvement in the maternal care of chicks in the native Thai hen ( Gallus domesticus )

Highlights • The role of the DA/PRL system in rearing behavior in birds was examined. • The majority of TH-ir neurons were observed in the nI and ML areas. • The number of TH-ir neurons in the nI and PRL levels were high in rearing hens. • The DAergic activity and PRL levels decline in chicks-depriv...

Zusammenfassung:	Highlights • The role of the DA/PRL system in rearing behavior in birds was examined. • The majority of TH-ir neurons were observed in the nI and ML areas. • The number of TH-ir neurons in the nI and PRL levels were high in rearing hens. • The DAergic activity and PRL levels decline in chicks-deprived hens. • The DA/PRL system may be involved in early rearing behavior of native Thai hen.
