Factors affecting vitamin E level in ruminant tissues

Abstract

Literature was surveyed to clarify the role of factors affecting vitamin E deposition in animal tissues and findings were compared. Special attention was paid to ruminants because of the rumen factor having a different environment for nutrients and being absent in monogastric animals. A hypothesis is proposed that even together with good quality grass high intakes of vitamin E may not protect the animal from a depletion of this vitamin in its tissues. Special attention must be given to diet ingredients and animal health status when vitamin E is used in ruminant diets.
