The mRNA relative expression of GnRHR, LHR and FSHR in chicken testis. The testis were collected for mRNA (real-time PCR) analysis. The mRNA abundance were normalized by β-actin. (A) Although the different treatments had no significant influence on GnRH content on day 21, the response was significantly up-regulated by the presence of n3/n6 (treatment 3, 4 and 5) on day 35 (***P < 0.001). (B) Treatment 2, 4 and 5 significantly increased FSHR mRNA compared with others treatments on day 21 (+++P < 0.001). (C) Diet with different ratios of n3/n6 PUFAs (treatment 2–5) significantly increased LHR mRNA level on day 21 (+++P < 0.001). The effect of PUFAs was decreased with the duration of treatment on day 35. (D) Although PUFAs had no significant effect on StAR content on day 21, the treatment 2–5 dramatically increased StAR mRNA level (**P < 0.01; ***P < 0.001). + indicates significant difference among treatments on day 21. * indicates significant difference among treatments on day 35.
