Nutrition of rodents.
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.
