Furthermore, because STAY is measured late in life (typically at 6\u2009years of age), it inherently prolongs generation intervals. To address this limitation, we evaluated an alternative approach using random regression models, which incorporate multiple phenotypes recorded throughout an animal's lifespan to generate predictive curves for breeding values. Using calving records from 179,001 Nellore cows, we compared two phenotypic expressions of longevity and aimed to identify the optimal random regression model for predicting breeding values. Ten specific ages were defined for functional longevity expressed as stayability (FLSTAY). At each age, a binary phenotype (1 or 0) was assigned based on whether the cow remained in the herd. Alternatively, for functional longevity associated with the number of calvings (FLNC), the cumulative number of calvings recorded up to each specific age was calculated. Models fitting Legendre orthogonal polynomials ranging from linear to cubic degrees were compared. The cubic polynomial proved most suitable for modelling FLSTAY, whereas the quadratic polynomial provided the best fit for FLNC. Predictive ability metrics of estimated breeding values for FLNC were superior to those for FLSTAY. Heritability estimates for FLNC (0.025\u20130.074) were consistently higher than those for FLSTAY (0.004\u20130.045). Similarly, genetic correlations across ages were generally stronger for FLNC, reaching 0.88 between 39 and 75\u2009months (the traditional age for selection). These findings suggest the feasibility of applying random regression models to FLNC, allowing its use as an early selection strategy to improve functional longevity.<\/jats:p>","DOI":"10.1111\/jbg.70067","type":"journal-article","created":{"date-parts":[[2026,8,10]],"date-time":"2026-08-10T14:25:14Z","timestamp":1786371914000},"page":"834-845","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Genetic Evaluation for Functional Longevity in Nellore Cattle"],"prefix":"10.1111","volume":"143","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-9557-5525","authenticated-orcid":false,"given":"Gabriele de Souza Silva","family":"Fernandes","sequence":"first","affiliation":[{"name":"Grupo de Melhoramento Animal de Mato Grosso (GMAT), Universidade Federal de Rondon\u00f3polis  Rondon\u00f3polis MT Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-7679-393X","authenticated-orcid":false,"given":"Dalila Ribeiro","family":"dos Santos","sequence":"additional","affiliation":[{"name":"Grupo de Melhoramento Animal de Mato Grosso (GMAT), Universidade Federal de Rondon\u00f3polis  Rondon\u00f3polis MT Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arione Augusti","family":"Boligon","sequence":"additional","affiliation":[{"name":"Departamento de Zootecnia Universidade Federal de Pelotas (UFPEL)  Pelotas RS Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8392-1304","authenticated-orcid":false,"given":"M\u00e1rio Luiz","family":"Santana","sequence":"additional","affiliation":[{"name":"Grupo de Melhoramento Animal de Mato Grosso (GMAT), Universidade Federal de Rondon\u00f3polis  Rondon\u00f3polis MT Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2221-1525","authenticated-orcid":false,"given":"Gilberto Romeiro de Oliveira","family":"Menezes","sequence":"additional","affiliation":[{"name":"Embrapa Gado de Corte  Campo Grande MS Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denise Rocha","family":"Ayres","sequence":"additional","affiliation":[{"name":"Grupo de Melhoramento Animal de Mato Grosso (GMAT), Universidade Federal de Rondon\u00f3polis  Rondon\u00f3polis MT Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annaiza Braga","family":"Bignardi","sequence":"additional","affiliation":[{"name":"Grupo de Melhoramento Animal de Mato Grosso (GMAT), Universidade Federal de Rondon\u00f3polis  Rondon\u00f3polis MT Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5772-6644","authenticated-orcid":false,"given":"Rodrigo Junqueira","family":"Pereira","sequence":"additional","affiliation":[{"name":"Grupo de Melhoramento Animal de Mato Grosso (GMAT), Universidade Federal de Rondon\u00f3polis  Rondon\u00f3polis MT Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,10]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/jas\/skaf035"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/jas\/sky390"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/jas\/skae364"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.2527\/jas.2016.1314"},{"key":"e_1_2_9_6_1","first-page":"625","volume-title":"Bayesian Statistics","author":"Geweke J.","year":"1992"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1186\/1297-9686-15-2-201"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0388.2007.00712.x"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0301-6226(01)00186-5"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.2527\/jas.2012-6126"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(97)75996-4"},{"key":"e_1_2_9_12_1","doi-asserted-by":"crossref","unstructured":"Lourenco D.
