The a-tocopherol content in liver was increased quadratically as dietary Vitamin E
content increased (P < 0:01); an interaction between dietary M/S and the quadratic effect
of Vitamin E was observed (P < 0:05) (Table 7). The significant incorporation of dietary
tocopherol into liver, the first tissue encountered after absorption, is not surprising and is in
accordance with other studies (Marusich et al., 1975; Machlin and Gabriel, 1982; Ueda and
Igarashi, 1990). This interaction, although minimal, is caused by a relatively smaller
increase of liver a-tocopherol by supplementing 10 mg Vitamin E kg1 of the diet and a
greater increase of liver a-tocopherol by supplementing 20 mg Vitamin E kg1 of the diet
with M/S of 4.8 comparing to diet with M/S of 1.2.
