Access to a diet that provides adequate nutrition is one of the most important environmental factors influencing the well-being of rodent colonies. The dietary ingredient and nutrient composition, as well as the potential biological and chemical contaminant concentrations, are factors for consideration in selecting diets for a specific rodent colony. Estimated nutrient requirements have been published for the rodent species that are commonly used in biomedical research. The nutrient concentrations in adequate diets for other captive rodent species that are not used in biomedical research are more difficult to obtain. However, reasonable estimates of their nutrient requirements can be obtained by extrapolation of data from rodent species of a similar metabolic weight and size or from nutrient concentrations of diets that have a history of acceptable performance in the species of interest. Captive rodent colonies should be provided with nutritionally balanced diets with only limited amounts of succulent foodstuffs. The practice of feeding rodent colonies specific cereal grains is discouraged, since no single grain provides a balanced rodent diet.
获得提供充足营养的饮食是影响啮齿动物群落健康的最重要环境因素之一。饮食成分和营养成分，以及潜在的生物和化学污染物浓度，是为特定啮齿动物群落选择饮食时需要考虑的因素。已公布了生物医学研究中常用啮齿动物物种的估计营养需求。对于未用于生物医学研究的其他圈养啮齿动物物种，其适宜饮食中的营养成分浓度更难获取。然而，通过推断代谢体重和体型相似的啮齿动物物种的数据，或从在目标物种中表现良好的饮食的营养成分浓度，可以获得对其营养需求的合理估计。圈养的啮齿动物群落应提供营养均衡的饮食，多汁食物的量应有限。不鼓励给啮齿动物群落喂食特定的谷物，因为没有单一的谷物能提供均衡的啮齿动物饮食。
