MANAGED FORMULATION, FIXED FORMULA OR LEAST COST - WHICH IS BEST?
Biomedical researchers advance science through experimental research conducted with animal models. Accurate results and meaningful conclusions are achieved only when tight control is maintained over all materials and methods used in every research study. The animal diet is a key variable that must be controlled and managed to minimize changes over time.
Variation in natural ingredient diets fed to animals involved in biomedical research could confound experimental results or influence the interpretation of results. Therefore, it is important to manage diet formulas and have tight controls when manufacturing the diet. In fact, it is unlikely that lots manufactured according to the same formulations would contain exactly the same concentrations of nutrients or contaminants as different batches of ingredients may be used.2
Three common practices used to formulate and manufacture animal diets including Managed Formulation (delivering CONSTANT NUTRITION®
), Fixed Formulation, and Least-Cost Formulation, which are detailed below.
