No interaction effects between factors studied (Cp, Vit E, and sex) were observed on the variables. Most productive traits were unaffected by Cp or Vit E inclusion. However, the Cp increased the feed conversion ratio during the first 20 days. The Cp group showed a higher CTTAD of ether extract and hemicellulose but lower CTTAD of crude protein. Pigs fed Cp had a lower plasmatic urea content than the control group. The high Vit E doses increased the CTTAD of every nutrient and the plasmatic α-tocopherol content. The pigs fed Cp tended to spend more time eating in the early morning, likely to mitigate tannins’ astringent effects. Dietary inclusion of 20% Cp in finishing high-conformation pigs is possible without affecting overall performance though it reduces nutrient CTTAD and increases feeding cost. Supra-nutritional doses of Vit E do not affect pig performance but increase the α-tocopherol deposition with potential antioxidant effects. info:eu-repo/grantAgreement/EC/H2020/801586/EU/International Doctoral Programme for Talent Attraction to the Campus of International Excellence of the Ebro Valley/IberusTalent This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 801586-IberusTalent info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.7 2024 VETERINARY SCIENCES 21 / 170 = 0.124 2024 Q1 T1 AGRICULTURE, DAIRY & ANIMAL SCIENCE 15 / 86 = 0.174 2024 Q1 T1 0.733 2024 Veterinary (miscellaneous) 2024 Q1 Animal Science and Zoology 2024 Q1 5.2 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Latorre, María Ángeles Universidad de Zaragoza (orcid)0000-0002-3005-2675 Lobón, Sandra Verdú, Marçal Álvarez-Rodríguez, Javier 2008 700 Universidad de Zaragoza Dpto.
