Note: Terminology used to describe laboratory animal diets is not consistent across the industry. In this context, we use the phrase “natural ingredient” to denote the relative lack of processing of the ingredients. Natural ingredient diets might also be referred to as “standard”, “grain-based” or “chow” — terms that may convey some information about the nature of the diet or how it is used but may not provide enough clarity for your purposes.
