ABSTRACT - Feed efficiency plays a major role in the overall profitability and sustainability of the beef cattle industry, as it is directly related to the reduction of the animal demand for input and methane emissions. Traditionally, the average daily feed intake and weight gain are used to calculate feed efficiency traits. However, feed efficiency traits can be analysed longitudinally using random regression models (RRMs), which allow fitting random genetic and environmental effects over time by considering the covariance pattern between the daily records. Therefore, the objectives of this study were to: (1) propose genomic evaluations for dry matter intake (DMI), body weight gain (BWG), residual feed intake (RFI) and residual weight gain (RWG) data collected during an 84-day feedlot test period via RRMs; (2) compare the goodness-of-fit of RRM using Legendre polynomials (LP) and B-spline functions; (3) evaluate the genetic parameters behaviour for feed efficiency traits and their implication for new selection strategies. The datasets were provided by the EMBRAPA–GENEPLUS beef cattle breeding program and included 2920 records for DMI, 2696 records for BWG and 4675 genotyped animals. Genetic parameters and genomic breeding values (GEBVs) were estimated by RRMs under ssGBLUP for Nellore cattle using orthogonal LPs and B-spline. Models were compared based on the deviance information criterion (DIC). The ranking of the average GEBV of each test week and the overall GEBV average were compared by the percentage of individuals in common and the Spearman correlation coefficient (top 1%, 5%, 10% and 100%). The highest goodness-of-fit was obtained with linear B-Spline function considering heterogeneous residual variance. The heritability estimates across the test period for DMI, BWG, RFI and RWG ranged from 0.06 to 0.21, 0.11 to 0.30, 0.03 to 0.26 and 0.07 to 0.27, respectively. DMI and RFI presented within-trait genetic correlations ranging from low to high magnitude across different performance test-day. In contrast, BWG and RWG presented negative genetic correlations between the first 3weeks and the other days of performance tests. DMI and RFI presented a high-ranking similarity between the GEBV average of week eight and the overall GEBV average, with Spearman correlations and percentages of individuals selected in common ranging from 0.95 to 1.00 and 93 to 100, respectively. Week 11 presented the highest Spearman correlations (ranging from 0.94 to 0.98) and percentages of individuals selected in common (ranging from 85 to 94) of BWG and RWG with the average GEBV of the entire period of the test. In conclusion, the RRM using linear B-splines is a feasible alternative for the genomic evaluation of feed efficiency. Heritability estimates of DMI, RFI, BWG and RWG indicate enough additive genetic variance to achieve a moderate response to selection. A new selection strategy can be adopted by reducing the performance test to 56days for DMI and RFI selection and 77days for BWG and RWG selection.

Resumo: A gomose é considerada a principal doença fúngica dos porta-enxertos de citros. As condições edafoclimáticas do estado de Mato Grosso são ótimas para o desenvolvimento da doença, favorecendo a mortalidade de plantas de limeira ácida ‘Tahiti’ enxertadas em limoeiro ‘Cravo’. Entre os porta-enxertos que reúnem as características de resistência à gomose e a capacidade de induzir copas menores, destaca-se o trifoliata [Poncirus trifoliata (L.) Raf.] ‘Flying Dragon’, sendo um dos porta-enxertos de maior uso na citricultura mundial. Assim, o objetivo do trabalho foi avaliar o crescimento vegetativo de plantas de limeira ácida ‘Tahiti’ enxertadas com porta-enxertos gerados e pré-selecionados pelo Programa de Melhoramento Genético de Citros da Embrapa, em Sorriso, num pomar experimental com cinco anos e meio de idade. O delineamento experimental foi de blocos ao acaso com doze tratamentos (porta-enxertos), quatro repetições, e parcelas de cinco plantas. Os porta-enxertos foram: citrandarins ‘Indio’ [C. sunki (Hayata) hort ex Tanaka x Poncirus trifoliata (L.) Raf. ‘English’] (CTRI) e ‘San Diego’ (C. sunki x P. trifoliata ‘Swingle’) (CTRSD), citrumelo ‘Swingle’ (C. paradisi Macfad. x P. trifoliata) (CTSW), limoeiro ‘Cravo’, clones ‘Santa Cruz’ e ‘CNPMF-003’, tangerineira ‘Sunki Tropical’ (C. sunki) e os híbridos HTR - 069, TSKC x (LCR x TR) - 059, LVK x LCR - 038, TSKC x TRFD 003, TSKC x CTSW – 028 e 041. As siglas HTR, TSKC, LCR, TR, LVK, TRFD e LRF correspondem a, respectivamente, híbrido trifoliolado, tangerineira ‘Sunki’ comum, limoeiro ‘Cravo’, P. trifoliata, limoeiro ‘Volkameriano’ (C. volkameriana V. Ten. & Pasq.), P. trifoliata ‘Flying Dragon’ e limoeiro ‘Rugoso da Florida’ (C. jambhiri Lush.). Foram avaliados altura de planta (H, m), diâmetro do caule (10 cm acima (DE, mm) e abaixo (DPE, mm) da linha de enxertia), diâmetro da copa (D, m), volume da copa (V, m3) e Índice de Vigor Vegetativo (IVV). As médias dos tratamentos foram agrupadas pelo teste de Scott-Knott (p<0,05). Observou-se que o citrumelo ‘Swingle’, o limoeiro ‘Cravo Santa Cruz’ e o ‘Cravo CNPMF-003’, foram superiores em relação aos demais porta-enxertos, principalmente nas características de altura de plantas, diâmetro e volume de copa da limeira ácida ‘Tahiti, enquanto que o híbrido TSKC x (LCR x TR) – 059 apresentou o menor desenvolvimento vegetativo.
