The highest values of the stress indicators—neutrophil-to-lymphocyte-ratio (N/L), non-esterified fatty acids (NEFA), serum cortisol and fecal cortisol metabolites (FCM)—were recorded after the road transportation of group F to the feedlot. No differences between the groups were identified at the end of the adaptation period, but at the end of the fattening, statistically significant higher values for NEFA and serum cortisol were determined in group F. However, statistically significant differences between the groups were not found in the percentage of lambs with clinical signs of illness and ovine respiratory complex (ORC) lesions or in the final weight of the lambs. Independent of the location at which the lambs were fattened, those with FCM values at the beginning of the study (at the time of weaning) in the highest quartile developed a higher percentage of clinical signs of illness (45.5% vs. 32.1%, p > 0.05) and ORC lesions (45.5% vs. 10.7%, p < 0.01), and their average final weight was lower (24.36 kg vs. 27.40 kg, p = 0.001) than those with values in the lowest quartile. Stress experienced by lambs prior to finishing seems to be relevant for their further development, and FCM concentration at the time of weaning could be used as an indicator of health and productive performance of the lambs during the fattening period, regardless of finishing location. info:eu-repo/grantAgreement/ES/DGA/A15-17R info:eu-repo/grantAgreement/ES/MINECO/AGL2015-67690-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.752 2020 VETERINARY SCIENCES 19 / 146 = 0.13 2020 Q1 T1 AGRICULTURE, DAIRY & ANIMAL SCIENCE 13 / 63 = 0.206 2020 Q1 T1 0.583 2020 Veterinary (miscellaneous) 2020 Q1 Animal Science and Zoology 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion González, José María Universidad de Zaragoza (orcid)0000-0002-4655-9171 Ramos, Juan José Universidad de Zaragoza (orcid)0000-0002-2724-2785 Marca, María Carmen Universidad de Zaragoza (orcid)0000-0003-0926-9586 Figliola, Lucía Ruiz de Arcaute, Marta Universidad de Zaragoza (orcid)0000-0002-7655-2472 Borobia, Marta Universidad de Zaragoza (orcid)0000-0002-0680-9957 Ortín, Aurora Universidad de Zaragoza (orcid)0000-0002-0313-5926 1009 617 Universidad de Zaragoza Dpto.
