Studies on the Absorption of Labelled and Dietary α-Tocopherol in Mink as Influenced by Some Dietary Factors

On the utilization, retention and status of vitamin E in mink (Mustela vison) under dietary oxidative stress

“…The apparent digestibility ofvitamin E varied from 60-76% depending on the concentration of dietary vitamin E showing a significant lower apparent digestibility from the diets containing high vitamin E levels. However, the calculated apparent digestibilities were considerably lower than those measured in the study by ESKELAND and RIMESLATTEN (1979). The authors postulate an absorption of about 90% of dietary vitamin E o n basis of the results of their chemical analysis.…”

“…Studies on the interaction of dietary PUFA in particular linoleic and linolenic acid and vitamin E have been conducted mainly in the rat (HOLLANDER 1981). It is commonly accepted that high dietary content of both fatty acids depress the intestinal absorption of vitamin E. A single study is available dealing with the absorption of vitamin E in mink under varying conditions with respect to quality and quantity of the dietary fat source (ESKELAND and RIMESLATTEN 1979). O n basis of tocopherol analysis in feed and feces the authors claim an absorption of 90% of dietary vitamin E.…”
