This study assesses the effects of including Cp in lambs’ diet and meat display time (0, 7, 9, and 11 days) in modified atmosphere packaging on meat colour, fatty acid (FA) composition, tocopherol levels, and lipid oxidation values in the Semimembranosus muscle of 40 light lambs. The lambs were fed with concentrates supplemented with increasing Cp levels (0, 150, and 300 g/kg) for 45 days before slaughter. Metmyoglobin (MMb) and malondialdehyde (MDA) contents increased linearly with display time (p < 0.05), regardless of diet (p > 0.05). At 11 days of display, MMb (28 ± 0.8%) and MDA (0.6 ± 0.1 mg MDA/kg of meat) contents remained within the acceptable limits. The α-tocopherol content was lower in the 30% Cp group and meat (p < 0.05). Total saturated and monounsaturated FA contents (934 ± 64 and 823 ± 65 mg/100 g of meat, respectively) did not differ significantly among the groups. However, the meat from lambs fed with 30% Cp showed reduced levels of branched-chain FAs, while polyunsaturated FAs increased (p < 0.05) compared to the control lambs. The inclusion of Cp in the lamb’s diet, up to 30%, did not lead to meat deterioration and improved certain quality parameters, including a healthier FA profile. These findings highlight Cp’s potential as an alternative antioxidant source in animal diets. 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/grantAgreement/ES/INIA/RTA2017-00008-C02 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 6.0 2023 BIOCHEMISTRY & MOLECULAR BIOLOGY 50 / 313 = 0.16 2023 Q1 T1 FOOD SCIENCE & TECHNOLOGY 20 / 173 = 0.116 2023 Q1 T1 CHEMISTRY, MEDICINAL 8 / 72 = 0.111 2023 Q1 T1 1.222 2023 Biochemistry 2023 Q1 Clinical Biochemistry 2023 Q1 Food Science 2023 Q1 Physiology 2023 Q1 Molecular Biology 2023 Q2 Cell Biology 2023 Q2 10.6 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lobón, Sandra (orcid)0000-0002-7829-1448 Latorre, María Ángeles Universidad de Zaragoza (orcid)0000-0002-3005-2675 Bertolín, Juan Ramón (orcid)0000-0001-6673-489X Álvarez-Rodríguez, Javier 2008 700 Universidad de Zaragoza Dpto.
