In this study, the effects of cage type and the light-dark cycle on the behavior of hens before, during, and after forced molting were determined. For this purpose, 73-week-old hens were placed in the two different cage types used in the experiment. The barley method was used to induce molting at 75 weeks of age. The molting period lasted 35 days in total. The frequencies of walking, feeding, comforting, and preening behaviors were affected by the forced molting period. The addition of enrichment materials to the cage did not cause any changes in hen behavior. The light-dark cycle was important for the frequency of all examined behaviors except fighting behavior. No interaction was found among forced molting period, cage type, and light-dark cycle regarding behaviors. It is thought that there is a decrease in welfare-related behaviors at the end of the laying period and this decrease does not increase with forced molting using barley; on the contrary, appropriate forced molting applied to hens during this period will increase welfare. It was observed that cage type did not cause a significant difference in hen behavior during the forced molting period.
本研究旨在确定笼型和光-暗周期对强制换羽前、中、后母鸡行为的影响。为此，将 73 周龄母鸡置于实验中使用的两种不同笼型中。75 周龄时采用大麦法诱导换羽。换羽期总共持续 35 天。行走、进食、安慰和梳理行为的频率受到强制换羽期的影响。向笼中添加丰容材料并没有引起母鸡行为的任何变化。光-暗周期对所有检查行为的频率都很重要，除了战斗行为。强制换羽期、笼型和光-暗周期之间没有观察到行为的相互作用。据认为，在产蛋期末，与福利相关的行为会减少，而使用大麦进行强制换羽不会增加这种减少；相反，在这个时期对母鸡进行适当的强制换羽将提高福利。观察到在强制换羽期间，笼型并没有导致母鸡行为出现显著差异。
