Abstract

Abstract:

To investigate the regulation of reproductive hormones in Danzhou chicken by follicle-stimulating hormone (FSH) and luteotropic hormone (LH),the concentration of FSH and LH in Danzhou chicken blood were changed by different treatments and the concentration of FSH,LH, prolactin (PRL), progesterone (P), and estradiol (E₂) in the blood were determined using the enzyme-linked immunosorbent assay (ELISA).The results showed that exogenous FSH and LH could improve the concentrations of FSH and LH,respectively. When one of FSH and LH increased alone,the concentration of PRL was significantly decreased (P < 0.05),while it was significantly increased when FSH and LH were both increased (P < 0.05).The high level of the FSH could result the significant increase of E₂ and P (P < 0.05),and it would expand the increasing effect in cooperation with the high concentration of LH. While the high level of the LH could elevate the concentration of E₂ and P,but effect was not significant (P > 0.05).In conclusion,the study suggested that the increase level of FSH or LH could reduce the concentration of PRL in Danzhou chicken,meanwhile,it could increase the concentration of E₂ and P in varying degrees. However,both of the FSH and LH increase in the blood could result the significant increase of E₂ and P as the synergy. When the concentration of E₂ and P were too high,it could stimulate the release of PRL which could adjust the concentration of FSH and LH,and rebalance the concentrations of E₂ and P in the blood.

Key words: Danzhou chicken; follicle-stimulating hormone (FSH); luteotropic hormone (LH); prolactin (PRL); estradiol (E₂); progesterone (P)
