“…Most of the studies about GxE in cows have been performed on cosmopolitan breeds (e.g., Holstein) from various countries (e.g., [ 17 , 24 ]), or Nellore [ 44 ]. Literature on native breeds and dual-purpose cattle is scarce (e.g., [ 45 , 46 ]), despite the fact that selection usually faces some technical problems related to GxE.…”

“…These authors have pointed out the re-ranking of animals as the main interaction effect of GxE in tropical production systems for traits with economic importance in breeding programs. In Nellore cattle, dissecting the GxE interaction is commonly assessed by reaction norm models [ 9 , 11 , 12 ]. The reaction norm model allows fitting the phenotypic information as a function of a continuous environmental gradient by including covariates, regulated by environmental and genetic factors, which are shared with the target trait [ 13 ].…”

“…Já para os valores genéticos dos top 10% animais nos diferentes ambientes, as correlações de Spearman foram de 0,58 a 0,98, assumindo o mesmo comportamento, sendo a maior correlação entre os valores genéticos preditos no ambiente de médio e de pior desempenho. Tais resultados sugerem que animais selecionados no ambiente de baixo desempenho podem ser utilizados no ambiente de produtividade média, e vice e versa (Silva et al,2019). A porcentagem de animais comuns dentro da classificação de top 10% animais em cada ambiente (Tabela 1) foi maior para os ambientes de médio e de pior desempenho (82,35%), seguida pela porcentagem em ambientes de melhor e de médio desempenho (76,47%), e de melhor e de pior desempenho (58,82%), indicando que existe reclassificação dos genótipos em função das diferenças ambientais.…”
