我们之前的研究表明，绿光或蓝光可以增强肉鸡的免疫反应；这项研究是为了评估绿色和蓝色单色光的组合是否会导致免疫反应的改善。选取192只爱拔雅亩雄性肉仔鸡，分别于0 ~ 26日龄进行白光、红光、绿光和蓝光照射。第27 ~ 49天，将绿光和蓝光组肉鸡中的一半分别切换到蓝光（G-B）和绿光（B-G）。与单色光组相比，G-B组抗新城疫病毒（NDV）和抗牛血清白蛋白（BSA） IgG水平分别升高11.9 ~ 40.3%和17.4 ~ 48.7% （P< 0.05）。与单色光组相比，G-B组小鼠外周血T淋巴细胞和B淋巴细胞的增殖、IL-2浓度分别提高了10.4 ~ 36.2%、10.0 ~ 50.0%和24.7 ~ 60.3% （P< 0.05）。但G-B组血清TNF-α浓度较其他组降低3.64-40.5%，实验结束时，G-B组与B-G组之间各项检测指标均无显著差异。由此可见，G-B与B-G单色光联合使用可有效提高肉鸡抗体效价、淋巴细胞增殖指数，缓解应激反应。由此可见，绿、蓝单色光组合可提高肉鸡免疫功能。
Our previous study suggested that green light or blue light would enhance the broiler immune response; this study was conducted to evaluate whether a combination of green and blue monochromatic light would result in improved immune response. A total of 192 Arbor Acre male broilers were exposed to white light, red light, green light, and blue light from 0 to 26 days. From 27 to 49 days, half of the broilers in green light and blue light were switched to blue light (G–B) and green light (B–G), respectively. The levels of anti-Newcastle disease virus (NDV) and anti-bovine serum albumin (BSA) IgG in G–B group were elevated by 11.9–40.3% and 17.4–48.7%, respectively, compared to single monochromatic lights (P< 0.05). Moreover, the proliferation of peripheral blood T and B lymphocytes and the IL-2 concentration in the G–B groups increased by 10.4–36.2%, 10.0–50.0% and 24.7–60.3% (P< 0.05), respectively, compared with the single monochromatic light groups. However, the serum TNF-α concentration in the G–B group was reduced by 3.64–40.5% compared to other groups, and no significant difference was found between the G–B and B–G groups in any type of detection index at the end of the experiment. These results suggested that the combination of G–B and B–G monochromatic light could effectively enhance the antibody titer, the proliferation index of lymphocytes and alleviate the stress response in broilers. Therefore, the combination of green and blue monochromatic light can improve the immune function of broilers.
