The daily food intake of captive red grouse was measured throughout the year. It was positively related to body weight and to daylength, and negatively to air temperature. Grouse ate more during their main summer moult, and the hens ate most while producing eggs. 2. The total weight of eggs laid was positively related to daily food intake during the 5 weeks before laying, but not to daily intake during laying. The rate at which eggs were laid was related to daily intake during laying as well as before laying. The possible significance of these results for poultry management is discussed.

全年对圈养红松鸡的每日食物摄入量进行了测量。它与体重和日照时长呈正相关，与气温呈负相关。松鸡在夏季主要换羽期食量更大，母鸡在产蛋时食量最大。2. 产蛋总重量与产蛋前5周的每日食物摄入量呈正相关，但与产蛋期间的每日摄入量无关。产蛋率与产蛋期间以及产蛋前的每日摄入量有关。讨论了这些结果对家禽管理的潜在意义。
