ABSTRACT
The concentrations of dry matter, cholesterol, saturated fat, monounsaturated fat, and 29 fatty acids were measured in four size categories of whole mice (Mus domesticus) that are commonly fed to zoo animals. Dry matter increased with age/size of mice, whereas cholesterol decreased with age/size. Significant differences in fatty acid content were found among mice categories with capric, lauric, and myristic acids. Mice categories had similar levels of palmitic, palmitoleic, heptadecenoic, stearic, oleic, linoleic, gamma linolenic, alpha linolenic, eicosenoic, eicosadienoic, arachidonic, docosahexaenoic, and lignoceric acids. Analyzed lipid content of mice exceeded domestic carnivorous animal requirements for linoleic and arachidonic acids. The fatty acid levels in mice were high, falling between published values in beef and fish. Generally, mice contained higher levels of polyunsaturated fatty acids, including the omega-3 fatty acids, and lower levels of saturated fatty acids than beef. Although fatty acid levels met or exceeded some dietary requirements for carnivores and omnivores, a possibility of excessive levels exists that could lead to eye and tissue abnormalities. Furthermore, as the intake of dietary polyunsaturated fatty acids increases, the dietary requirement for vitamin E increases. Thus, it is important that lipid profiles of feeder mice be known and considered when examining captive animal diets.
