“…Legendre polynomials of various order have been largely used in reaction norm models for GxE in livestock (e.g., [ 6 , 76 , 77 ]). Variations in the ZGZ′ variance or in the heritability of traits are often observed along the environmental gradient provided by the reaction norm (e.g., [ 6 , 24 , 29 ]), especially when the range of the environmental descriptor is very large (i.e., temperature-humidity index) [ 78 ].…”

“…Many studies have considered climate characteristics such as temperature-humidity variation as an environmental covariate in modelling (e.g., [ 24 ]), but other conditions such as herd management (e.g., [ 25 ]) or average production level (e.g., [ 26 ]) can also be considered. Reaction norm can be modelled using a single-step or two step analysis: the first is generally used when a climatic descriptor such as temperature or the temperature-humidity index (THI) is directly used as an environmental covariate [ 8 , 24 , 27 ], whereas a two-steps model is applied when herds of similar conditions (often called contemporary groups) are considered as an environmental gradient [ 11 , 28 , 29 ]. This last form of modelling is particularly useful when various geographical and farm-management conditions characterize the rearing systems in a breed, such as in Brown Swiss of Germany and Austria [ 10 ], and Rendena [ 30 ], which is the study subject.…”

“…Similarly, Gerber et al [31], Huquet et al [32], Calus et al [21], and Schmid et al [33] studied macro-environmental plasticity for production traits in German Simmental, French Holstein, Dutch Holstein Friesian cattle, and German Brown Swiss cattle, defining the environmental conditions with different management parameters. Similarly, Santos et al [34] and Mulim et al [35,36] studied production traits in Brazilian Holstein, and Bohlouli et al [37] studied production traits as well as milk fat composition in German Holstein.…”

“…De acordo com Albuquerque (2004) Os modelos de normas de reação foram utilizados em diversos estudos que investigaram a ocorrência de IGA em características de produção de leite (SANTANA Jr. et al, 2016;SANTANA Jr. et al, 2019;CHERUIYOT et al, 2020;SANTOS et al, 2020;BOHLOULI et al, 2021;ERBE et al, 2021;MULIM et al, 2021a;TORO-OSPINA et al, 2022).…”

“…Apesar de terem utilizado critérios de classificação dos touros diferentes do apresentado neste trabalho,Santos et al (2020), ao trabalharem com dados de animais da raça Holandesa, observaram que a maioria dos touros foram classificados como extremamente robustos para as características de produção de leite, gordura e proteína. Esse comportamento também foi observado porSantos et al (2019) para peso aos 365 e 550 dias de idade de animais Guzerá e Ambrosini et al (2016) para características de crescimento de bovinos Nelore.…”
