Absorption and Distribution of Vitamin E in the Tissues

Effect of dietary supplementation of vitamin E in pigs to prevent the formation of carcinogenic substances in meat products

“…Vitamin E cannot be synthesized in animals, and therefore its presence in animal tissue reflects dietary availability. Due to the fat soluble characteristics of vitamin E, its absorption is dependent on the ability of the animals to digest and absorb fat (Wiss et al, 1962). Studies on pigs (Asghar et al, 1991;Monahan et al, 1993), chickens (Asghar et al, 1990;Lauridsen et al, 1997) and steers (Arnold et al, 1993) showed that dietary vitamin E supplementation significantly increased the α-tocopherol content of muscle membranes.…”

Oxycarotenoids in Poultry Feeds

“…Hislop and Whittle (406) noted that α-tocopherol is an effective antioxidant protecting substances sensitive to oxidation during storage, both in the feed (in vitro) and in the digestive tract (in vivo). Wiss et al (888) presented comparative data on the uptake of vitamin Ε and a synthetic antioxidant (ethoxyquin) in rats. Its role as a tissue antioxidant was reviewed by Marusich (543).…”

Der Einfluss von Art und Menge des Futterfettes auf die Verwertung von Canthaxanthin sowie der Vitamine A und E durch die Legehenne

“…N obile und Irving [1966] fanden ähnliche Ergebnisse in Versuchen mit Legehennen. Nach Wiss et al [1962] sowie Vogtm a n n und P ra bucki [1969] wird durch steigende Tokopherolgaben im Futter der Vitamin-E-Gehalt von Plasma und Leber bei der Legehenne in gleichem Sinn, nur be deutend stärker beeinflusst.…”
