A total of 48 Duroc x (Landrace x Large White) females of 26.5 ± 3.70 kg body weight (BW) were used to evaluate the impact of immunocastration and to find the optimum application time of the second dose for immunocastration on growth; sex hormones; reproductive tract development; and carcass, meat, and fat quality. Gilts were allocated to four experimental treatments (n = 12): control (entire gilts, EG) and immunocastrated gilts (IG), providing the second dose at 12, 9, or 7 weeks before slaughter (with approximately 60, 75, or 90 kg BW, respectively). Mean slaughter BW was 125 kg. Immunocastrated gilts had lighter reproductive tracts and greater fat thickness than EG. Fat from IG was more saturated and less polyunsaturated than that from EG. Numerically, gilts immunocastrated 9 and 12 weeks before slaughter presented higher fatness than those immunocastrated 7 weeks before slaughter. In conclusion, immunocastration is a good strategy to improve the fatness of gilts destined to dry-cured ham elaboration, with the optimum time for the second dose application seemingly between 9 and 12 weeks before slaughter. 000102127 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/AGL2016-78532-R$$9info:eu-repo/grantAgreement/ES/UZ/UZ2016-CIE-05 000102127 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000102127 590__ $$a3.231$$b2021 000102127 592__ $$a0.61$$b2021 000102127 594__ $$a2.7$$b2021 000102127 591__ $$aVETERINARY SCIENCES$$b16 / 145 = 0.11$$c2021$$dQ1$$eT1 000102127 593__ $$aVeterinary (miscellaneous)$$c2021$$dQ1 000102127 591__ $$aAGRICULTURE, DAIRY & ANIMAL SCIENCE$$b13 / 63 = 0.206$$c2021$$dQ1$$eT1 000102127 593__ $$aAnimal Science and Zoology$$c2021$$dQ1 000102127 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000102127 700__ $$aCarcò, G. 000102127 700__ $$0(orcid)0000-0001-5981-5448$$aMiana Mena, F.J.$$uUniversidad de Zaragoza 000102127 700__ $$0(orcid)0000-0001-9907-2941$$aMitjana, O.$$uUniversidad de Zaragoza 000102127 700__ $$0(orcid)0000-0001-6964-7011$$aFalceto, M.V.$$uUniversidad de Zaragoza 000102127 700__ $$0(orcid)0000-0002-3005-2675$$aLatorre, M.A.$$uUniversidad de Zaragoza 000102127 7102_ $$11012$$2410$$aUniversidad de Zaragoza$$bDpto.
