Brenes, Agustín Ministerio de Ciencia e Innovación (España) Comunidad de Madrid Trabajo presentado al 68th Annual Meeting of the European Federation of Animal Science (EAAP) celebrado en Tallinn (Estonia) del 28 de agosto al 1 de septiembre de 2017. Grape skin is a source of polyphenols with antioxidant and antimicrobial properties. Little information is available regarding its application in animal feeds. An experiment was conducted to investigate the effect of inclusion of fermented (FS) and unfermented (UFS) grape skin at different doses (30 g/kg, FS30 and UFS 30, and 60 g/kg, FS60 and UFS60) and of alfa-tocopheryl acetate (200 mg/kg) in broilers fed a corn-soybean diet. Growth performance, ileal protein digestibility, ileal and excreta content, digestibility of total polyphenols and tannins, thigh meat lipid oxidation (at 1 and 7 days of storage) and intestinal microflora in one hundred and fifty 21-day-old broiler chickens were determined. Growth performances were negatively affected by dietary FS60 and UFS60. Protein digestibility decreased in birds fed UFS60. The UFS supplementation increased ileal and excreta toatl polyphenols content; whereas ileal and excreta tannins content increased in all experiment groups. Birds fed UFS30 showed a higher value of polyphenols digestibility. Excreta digestibility of total polyphenols increased in birds fed FS and UFS compared to the control group, with higher value in birds fed UFS in comparison to those fed FS. Oxidative stability of thigh meat lipid oxidation. Intestinal microflora was not affected by dietary treatment. In conclusion, grape skin (at 60 g/kg) impaired chicken growth performance and protein digestibility. Total polyphenols content were more bioavailable in the large intestine tahn in the small intestine. The antioxidant potential of FS and UFS grape skin was not effective as vitamin E.
