Two basic diets (commercial rodent pellets or seeds) with or without supplements of carbohydrate were tested for growth and development, and effects on organ weights and serum calcium in male golden hamsters. The additional influence of photoperiod was measured. The data suggest that a seed diet alone is not adequate for growth. Addition of seeds and/or carbohydrate to the pellet diet increases growth rates substantially compared to the pellet diet alone. There are significant interaction effects on reproduction between diet and photoperiod indicating that diet can modify responses to short photic input. While reproduction remains essentially normal in seed-fed animals in long photoperiods, the rate of reproductive involution in short photoperiods is greatly enhanced. Added carbohydrate appears to offer some protection against the adverse effect of short photoperiods on reproduction. Even though calcium supplements to the diet increase serum calcium levels toward normal, growth rates are not improved. Addition of Tenebrio (grain beetle) larvae to the seed diet induces growth rates comparable to those of control animals, yet serum calcium levels remain significantly lower.
用两种基础饮食（商业啮齿动物颗粒饲料或种子），添加或不添加碳水化合物补充剂，对雄性金黄仓鼠的生长发育、器官重量及血清钙水平的影响进行了测试。同时测定了光周期的额外影响。数据表明，仅种子饮食不足以支持生长。与仅颗粒饲料饮食相比，在颗粒饲料饮食中添加种子和/或碳水化合物可显著提高生长速率。饮食和光周期对繁殖有显著的交互作用，表明饮食可改变对短光照输入的反应。在长光周期下，以种子为食的动物繁殖基本正常，但在短光周期下，生殖退化速率大大加快。添加碳水化合物似乎能为短光周期对繁殖的不利影响提供一定保护。尽管饮食中添加钙补充剂可使血清钙水平恢复正常，但生长速率并未提高。在种子饮食中添加黄粉虫幼虫可诱导生长速率与对照动物相当，但血清钙水平仍显著较低。
