Dietary vitamin E inhibits the trans 10-18:1 shift in beef backfat

[EN]Forty feedlot steers were fed a barleygrain-based finishing diet typical for western Canada, with two levels of supplementary vitamin E (468 or 1068 IU head_1 d_1) and the effect on backfat trans-18:1 isomeric profile was determined. Feeding 1068 IU vitamin E reduced the total trans-18:1 content...

Feeding 1068 IU vitamin E reduced the total trans-18:1 content in backfat (P<0.01), as well as the percentage of trans 10-18:1 (P<0.001), which are related to an increased risk for cardiovascular diseases. On the other hand, trans 11-18:1 (vaccenic acid) the precursor for cis 9,trans 11- 18:2 (rumenic acid), which have several purported health benefits, increased (P<0.01). Vitamin E could, therefore, be used to decrease trans-18:1 in beef and improve its isomeric profile.[FRE]Quarante bouvillons d’engrais ont reçu une ration de finition à base d’orge typique à celle employée dans l’ouest du Canada, mais enrichie de vitamine E à deux concentrations (468 ou 1 068 UI par tête, quotidiennement), avant établissement du profil isomérique des acides gras trans-18:1 pour le gras dorsal. La dose de 1 068 UI de vitamine E diminue la concentration totale d’acides gras trans-18:1 dans le gras dorsal (P<0,01), ainsi que la proportion des acides gras trans 10-18:1 (P<0,001) associés à un risque plus élevé de maladies cardiovasculaires. Parallélement, on note une hausse (P<0,01) de la concentration de l’acide gras trans 11-18:1 (acide vaccénique), précurseur de l’acide gras cis 9,trans 11-18:2 (acine ruménique), qu’on présume avoir plusieurs effets bénéfiques sur la santé . Par conséquent, on pourrait se servir de la vitamine E pour réduire la concentration d’acides gras trans-18:1 dans le boeuf et rehausser le profil isomérique de cette viande.Agricultural Institute of Canada201220122010info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10810/8220reponame:Addi.
