Concentrations of prolactin, growth hormone, testosterone, progesterone, thyroxine and triiodothyronine were measured in the blood plasma of female turkeys during successive periods of egg laying, a decline in lay, a moult induced by a short photoperiod (6 light: 18 dark) and a resumption of egg laying induced by a long photoperiod (16L:8D). 2. Concentrations of prolactin, growth hormone, testosterone and progesterone were higher in laying birds than in birds which were moulting or not laying. 3. The concentration of testosterone, but not of the other hormones studied, increased significantly during the period of profuse moult. 4. Concentrations of the thyroid hormones did not change with the varying physiological condition of the birds. However, the concentration of thyroxine was depressed by the long photoperiod.

在雌性火鸡连续产蛋期、产蛋量下降期、短光照周期（6小时光照：18小时黑暗）诱导的换羽期以及长光照周期（16小时光照：8小时黑暗）诱导的产蛋恢复期中，对其血浆中的催乳素、生长激素、睾酮、孕酮、甲状腺素和三碘甲状腺原氨酸浓度进行了测定。2. 产蛋期火鸡体内催乳素、生长激素、睾酮和孕酮的浓度高于换羽期或不产蛋期的火鸡。3. 在大量换羽期，睾酮浓度显著升高，而其他所研究的激素浓度未升高。4. 甲状腺激素浓度并未随火鸡生理状态的变化而改变。然而，长光照周期会使甲状腺素浓度降低。
