[FR] Quarante agneaux de race Assaf en engraissement (âge initial de 14 semaines) ont reçu de la paille d’orge (200 g/jour) et un concentré (30 g/kg poids vif) renfermant 1,5 g de naringine/kg (NAR) ou sans cet additif (TEMOIN) pour étudier de l’effet de ce flavonoïde sur les niveaux plasmatiques de triglycérides (TAG) et sur le contenu dans le gras intramusculaire et hépatique. Une prise de sang a été effectuée sur tous les animaux le jour 0 puis une fois par semaine. L’expérience a duré 7 semaines, après quoi, dix animaux par groupe ont été abattus. Pendant la 2ème et la 3ème semaine on a observé une diminution significative des TAG dans les niveaux plasmatiques des agneaux mâles correspondants au groupe NAR et comparés au groupe témoin (P0.05) entre les agneaux NAR et témoin. En résumé, nous obtenons un effet réducteur transitoire des TAG quand on ajoute la naringine au concentré pour les agneaux d’engraissement.
[EN] Forty Assaf fattening lambs (initial age 14 weeks) fed barley straw (200 g/day) and concentrate feedstuff (30 g/kg BW per day) including 1.5 g naringin/kg DM (NAR group, n=10 males and 10 female lambs) or not (CONTROL group, n=10 males and 10 female lambs) were used to study the effect of this flavonoid on plasma triacylglycerol (TAG) levels, and liver and intramuscular fat content. All the animals were blood sampled on day 0 and thereafter with a weekly frequency. The experimental period lasted 7 weeks and 20 animals (ten per group) were slaughtered. During weeks 2 and 3 a significant (P0.05) between NAR and CONTROL lambs. In summary, we report a transitory TAGreducing effect of naringin added to the feedstuff for fattening lambs.
