A well-balanced diet, along with plenty of clean, fresh water, is essential for proper animal health. TestDiet® manufactures an extensive line of animal diets for research purposes, each carefully formulated to accommodate the nutritional requirements of laboratory animals. These requirements, the major components of food, are briefly described to provide an overview of basic animal nutrition.

Storage/Shelf Life

Storage conditions as well as dietary characteristics affect the nutrient stability of laboratory animal diets. Such non-dietary factors include, but may not be limited to, lighting, oxygen, temperature and moisture. Antioxidants and fat in diet formulations can also affect the overall stability. Our extensive data prove that the manufacturers’ warranty of LabDiet® products can be extended beyond the recommendations in the Guide for Care and Use of Laboratory Animals by storing products under climate-controlled conditions. Irradiation can also extend the stability of a diet preventing growth of bacteria, yeasts and molds. Extension of your diet usage by controlled storage varies depending on the type of diet. The recommended shelf life based on proved product stability data for our LabDiet® and TestDiet® products is provided below. A quick-reference table is included along with a detailed description of each category of our products.


Each nutritional component has a specified unit of measurement.
