The ACVN Circle of Nutrition logo illustrates the iterative process of veterinary nutrition.


To determine the role of nutrition in veterinary patients and groups of animals, a systematic method is employed to ensure that all appropriate facets of nutrition are assessed. There are 3 aspects to be assessed in every case:


  • Animal factors of one or a group (herd, flock, etc.) – this includes the nutritional assessment
  • Feed (diet, ration, food, water, etc.) factors – this includes the diet history and diet assessment
  • Method of providing/delivering nutrition (feed/water) to the animal or a group of animals – this includes the assessment of the feeding methods and environmental factors


This process involves a repeating systematic evaluation of all 3 aspects affecting the nutritional status of a given animal(s) as often or as few times as needed. There is no one best place to start and there is no one best order by which to proceed, but all 3 need be assessed.
