In each of the tissues evaluated (liver, heart, and
adipose), α-tocopherol concentrations increased as the
dietary vitamin E level increased (P < 0.01). When 5%
fat was fed the liver and adipose both had higher α-
tocopherol concentrations (P < 0.01), but the heart muscle
tissue was not affected by the dietary fat addition
(P > 0.15). An interaction effect between dietary vitamin
E level and fat occurred for liver (P < 0.05) but not for
the adipose (P > 0.15) tissue. When the diet contained
fat and vitamin Eat 60 IU/kg diet, the liver had a higher
α-tocopherol concentration than did the adipose tissue.
