The effect of dietary variety on meal size was investigated in golden hamsters. Hamsters ate meals (four courses x 12 min/course) in which either the same food was offered in all four courses (one of powdered Purina chow, shortcake cookie, process cheddar cheese, or milk chocolate) or four different foods were offered in successive courses. Total energy intake was significantly greater in the variety condition than in any of the single-food conditions. Thus, although previous research indicates that the meal size of hamsters is relatively resistant to change, hamsters do increase meal size in response to dietary variety. This finding indicates that the satiety mechanisms of golden hamsters share at least some important features with those of other species.
在金黄仓鼠中研究了食物种类对进食量的影响。仓鼠进食餐食（四道菜，每道菜12分钟），其中要么在所有四道菜中都提供相同的食物（普瑞纳粉状饲料、松饼饼干、加工切达干酪或牛奶巧克力中的一种），要么在连续的几道菜中提供四种不同的食物。在食物种类多样的情况下，总能量摄入量显著高于任何单一食物的情况。因此，尽管先前的研究表明仓鼠的进食量相对不易改变，但仓鼠确实会因食物种类多样而增加进食量。这一发现表明，金黄仓鼠的饱腹感机制与其他物种的饱腹感机制至少有一些重要特征相同。
