本研究评估了单色光对鸽子产蛋量、蛋重、受精率、血浆性激素水平及其HPG轴受体mRNA水平的影响。将60对成年白色王鸽随机分为4组，分别暴露于紫光（VL）、绿色（GL）、红光（RL）和白色光（WL）。暴露于单色光包括16小时光照，每24小时一次，持续100天。每组各取9对配对鸽进行雌二醇（E2）和睾酮（T）分析，并从4组中随机选取24对配对鸽进行雌激素受体（ER）β和雄激素受体（AR）表达分析。结果表明，RL组的产蛋量显著高于WL和VL组（P< 0.05）。单色光对蛋重和受精率的影响不显著（P> 0.05）。雌鸽血浆E2水平RL组显著高于VL组（P< 0.05）。雄鸽血浆T含量差异不显著（P> 0.05）。雌鼠垂体ER βmRNA表达水平明显升高（P< 0.05），卵巢ER βmRNA表达水平明显升高（P< 0.01）。雄性大鼠垂体和睾丸中AR mRNA的表达量RL组最高，WL组最低（P< 0.01）。结果表明，RL能提高产蛋量，并能提高卵巢中E2浓度、ERβ表达以及垂体和睾丸中AR的表达。
This study evaluated the effects of monochromatic light on egg production, egg weight, fertility rate, plasma sex hormone levels, and their receptor mRNA levels in the HPG axis of pigeons. Sixty paired adult White King pigeons were randomly divided into four groups, exposed to violet light (VL), green light (GL), red light (RL), or white light (WL). Exposure to monochromatic light comprised 16 h of light, every 24 h for 100 days. Nine paired pigeons from each group were selected for estradiol (E2) and testosterone (T) analysis, and 24 paired birds were randomly selected from the four groups forERβandARexpression analysis. Results showed that RL increased egg production more than WL and VL (P< 0.05). No significant difference was observed in egg weight or fertility rate of birds exposed to monochromatic light (P> 0.05). Plasma E2in female pigeons exposed to RL was higher than that in those exposed to VL (P< 0.05). No significant difference was noted in plasma T levels in male pigeons (P> 0.05). In females, GL increasedERβmRNA levels in the pituitary (P< 0.05), and RL significantly increasedERβexpression in the ovary (P< 0.01). In males, RL induced the highestARmRNA levels, and WL induced the lowest levels in the pituitary and testis (P< 0.01). In conclusion, the results suggest that RL improves egg production, and enhances E2concentration,ERβexpression in the ovary, andARexpression in the pituitary and testis.
