摘要： 本研究比较了单色光对肉鸡SCN和视顶盖SGC层神经元c-Fos表达的影响。以LED灯为单色光源，选用刚出壳的雄性AA肉鸡40羽，分别饲养在白光（400~700 nm）、红光（660 nm）、绿光（540 nm）和蓝光（480 nm）下14 d，光照度为15 lx。光照制度20 h∶4 h（L∶D）。结果显示，在SCN中，蓝光组cFos表达分别显著低于白光、红光和绿光组29.76%、17.88%和22.23%（P<0.05），白光组与红、绿光组差异不显著（P>0.05）。同样，在视顶盖SGC层中，蓝光组cFos表达也显著低于白光、红光和绿光组17.78%、21.75%和23.63%（P<0.05），白光组与红、绿光组差异也不显著（P>0.05）。结果表明，与红光和绿光相比，蓝光抑制视顶盖SGC层和SCN神经元c-Fos的表达。

Abstract: This study was conducted to compare the effect of monochromatic light on expression of c-Fos in the SGC of optic tectum and SCN in broilers. Forty onedayold male AA (Arbor Acres) broilers were respectively reared under four light treatments, white (400-760 nm), red (660 nm), green (560 nm), blue (480 nm) by using LED (light-emitting diodes) as light sources until the 14th day.Light intensity was 15 lx. Light exposure was scheduled for 20 hours of light and 4 hours of darkness during the entire experiment. The results showed: in the SCN, c-Fos expression of BL group were significantly lower by 29.76%， 17.88% and 22.23% than that of WL, RL and GL groups respectively (P<0.05), no significant difference were found among WL, RL and GL groups (P>0.05). Similarly, c-Fos expression of BL group were significantly lower by 17.78%， 21.75% and 23.63%than that of WL, RL and GL groups, respectively (P<0.05), no significant difference were also found among WL, RL and GL groups in the SGC of optic tectum (P>0.05). These results suggested that blue light suppress c-Fos expression of neuron in the SCN and SGC of optic tectum compare to red and green light to some extent.
