Effects of xylanase enzyme supplementation to corn/wheat-based diets on performance and egg quality in laying hens. Can. J. Anim. Sci. 90: 207-212. This study was conducted to determine the effects of xylanase supplementation of corn/wheat-based diets on the performance and egg quality of laying hens. At 52 wk of age, 180 White Leghorn LSL laying hens were fed 15 diets, consisting of five corn:wheat ratios and three levels of enzyme. None of the treatments affected performance or egg quality, except for egg yolk index and egg yolk color. The egg yolk color was improved by the increase in dietary corn level. It is concluded that wheat can be used instead of corn as an energy feedstuff in laying hen diets.Cufadar, Y., Yıldız, A. O¨. et Olgun, O. 2010. Incidence d’un supple´ment de xylanase dans les rations de maı¨s/ble´ sur le rendement et la qualite´ des œufs des pondeuses. Can. J. Anim. Sci. 90: 207 212. L’e´tude devait e´tablir les effets d’un supple´ment de xylanase dans les rations de maı¨s/ble´ sur le rendement et la qualite´ des œufs des pondeuses. Cent quatrevingts pondeuses Leghorn blanches LSL de 52 semaines ont rec¸u quinze rations compose´es de 5 proportions diffe´rentes maı¨s/ble´ et de trois concentrations diffe´rentes d’enzyme. Aucun traitement n’a affecte´ le rendement ni la qualite´ des œufs, hormis la couleur et l’indice du jaune. La couleur du jaune s’ame´liore avec la proportion de maı¨s dans la ration. On en conclu qu’on pourrait remplacer le maı¨s par du ble´ comme source d’e´nergie dans la ration des pondeuses.en10.4141/CJAS09081info:eu-repo/semantics/openAccessEgg qualityLaying henPerformanceXylanaseQualite´ des œufsPondeuseRendementXylanaseArticle902207212Q2WOS:000280176600011Q2
