Última Reaction norms models in the adjusted weight at 550 days of age for Polled Nellore cattle in Northeast Brazil R. Bras. Zootec. Ambrosini,Diego Pagung; Carneiro,Paulo Luiz Souza; Braccini Neto,José; Martins Filho,Raimundo; Amaral,Rosimira dos Santos; Cardoso,Fernando Flores; Malhado,Carlos Henrique Mendes. The objective of this study was to evaluate the genotype-environment interaction (GEI) in the body weight adjusted to 550 days of age (W550) of Polled Nellore cattle raised in Northeastern Brazil using reaction norms (RN) models. Hierarchical RN models included fixed effects for age of cow (linear and quadratic) and random effects for contemporary groups (CG) and additive genetic RN level and slope. Four RN hierarchical models (RNHM) were used. The RNHM2S uses the solutions of contemporary groups estimated by the standard animal model (AM) and considers them as environmental level for predicting the reaction norms and the RNHM1S, which jointly estimate these two sets of unknowns. Two versions were considered for both models, one with a homogeneous (Hm) and...
