In this context, multi\u2010breed methodologies that integrate information from genetically related populations have emerged as a promising strategy to improve prediction accuracy and calibration under data\u2010scarce conditions. This study evaluated different genomic prediction approaches in a multi\u2010breed population of Zebu cattle, including Nellore, Guzerat, Brahman, and Tabapua, using 653\u2009785 phenotypic records, 190\u2009865 genotypic records, and 3\u2009681\u2009158 pedigree records. The traits analyzed were rib eye area (REA), rump fat thickness (RFT), age at first calving (AFC), and accumulated productivity (ACP). Genomic estimated breeding values were obtained using the single\u2010step GBLUP method under four models: single\u2010breed (G\n                    <jats:sub>SB<\/jats:sub>\n                    ), standard multi\u2010breed (G\n                    <jats:sub>0<\/jats:sub>\n                    ), metafounders (MF), and an adjusted genomic relationship matrix (AGR). Model performance was assessed using the linear regression method, which compares predictions from complete and partial datasets to estimate accuracy, bias, and dispersion. Multi\u2010breed models, particularly MF and AGR, produced higher accuracy than the single\u2010breed approach in several analyses for underrepresented breeds such as Guzerat, Brahman, and Tabapua, especially for carcass and reproductive\u2010related traits. For example, in Guzerat, REA accuracy increased from 0.44 with G\n                    <jats:sub>SB<\/jats:sub>\n                    to 0.62 with AGR, while in Tabapua, ACP accuracy improved substantially from 0.23 with G\n                    <jats:sub>SB<\/jats:sub>\n                    to 0.51 with AGR. These results highlight the importance of leveraging genetically related breeds and well\u2010structured reference populations to improve the reliability of genomic predictions in Zebu cattle under limited data conditions.\n                  <\/jats:p>","DOI":"10.1002\/age.70188","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T08:20:50Z","timestamp":1787214050000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Multi\u2010Breed Genomic Prediction Models for Carcass and Reproductive Traits in Zebu Beef Cattle"],"prefix":"10.1002","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3810-7319","authenticated-orcid":false,"given":"Gabriel","family":"Gubiani","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine, Faculty of Animal Science and Food Engineering University of S\u00e3o Paulo  Pirassununga Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1003-7977","authenticated-orcid":false,"given":"Larissa","family":"Temp","sequence":"additional","affiliation":[{"name":"Department of Animal Science, School of Agricultural and Veterinary Sciences S\u00e3o Paulo State University (UNESP)  Jaboticabal Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6522-5567","authenticated-orcid":false,"given":"Marisol","family":"Londo\u00f1o\u2010Gil","sequence":"additional","affiliation":[{"name":"Department of Animal Science, School of Agricultural and Veterinary Sciences S\u00e3o Paulo State University (UNESP)  Jaboticabal Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3215-9724","authenticated-orcid":false,"given":"Miller","family":"Teodoro","sequence":"additional","affiliation":[{"name":"Department of Animal Science, School of Agricultural and Veterinary Sciences S\u00e3o Paulo State University (UNESP)  Jaboticabal Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduarda","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Department of Animal Science, School of Agricultural and Veterinary Sciences S\u00e3o Paulo State University (UNESP)  Jaboticabal Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1038-4752","authenticated-orcid":false,"given":"Ignacio","family":"Aguilar","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Investigaci\u00f3n Agropecuaria (INIA)  Canelones Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5374-0710","authenticated-orcid":false,"given":"Matias","family":"Bermann","sequence":"additional","affiliation":[{"name":"Department of Animal and Dairy Science University of Georgia  Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Lourenco","sequence":"additional","affiliation":[{"name":"Department of Animal and Dairy Science University of Georgia  Athens Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelica S.
