Abstract
Eight adult rams were housed in 16L:8D for 16 weeks and then exposed to short days (8L:16D) or 'skeleton' short days (11L:1D:5L:7D) for 16 weeks before being returned to long days. The 'skeleton' treatment promoted testicular development and regression in a way similar to that occurring in 8L:16D, indicating that a change in the total quantity of light is not a prerequisite for the photoperiodic response in the ram.
摘要
八只成年公羊在16小时光照：8小时黑暗的条件下饲养16周，然后暴露于短日照（8小时光照：16小时黑暗）或“骨架式”短日照（11小时光照：1小时黑暗：5小时光照：7小时黑暗）环境中16周，之后再恢复到长日照。“骨架式”处理以类似于8小时光照：16小时黑暗条件下的方式促进了睾丸的发育和退化，这表明光照总量的变化并非公羊光周期反应的先决条件。
