Intensive rearing in confinement as a management strategy in beef cattle - lite...
Batistelli, Igor José Carvalho; Batistelli, Juliana Carla de Oliveira Rodrigues; Bess, Bruno Luiz; Menezes, Flávio Luiz deThis literature review aims to explain questions about the intensive rearing strategy of beef calves confined at the time of rearing, especially during the dry season, with emphasis on the intensification of rearing and reduction of grazing pressure. In Brazil, the predominant production system in beef cattle raising is the extensive system in which the base is mainly in tropical and temperate pastures, still w...
Genotype-environment interaction effects on weight gain in cattle using reactio...
Zubler, Rafaela; Araújo, Cláudio Vieira de; Menezes, Flávio Luiz de; Mota, Rodrigo Reis; Araújo, Simone Inoe; Lôbo, Raysildo BarbosaThe existence of genotype-environment interaction (GEI) using reaction norm models and their impact on the genetic evaluation of Nellore sires for body weight at 120, 210, 365 and 450 days of age was verified. Three models were used: animal model (AM) that disregards GEI and the one-step reaction norm model with homogeneous and heterogeneous residual variance (1SRNMH_het). Bayes Inference via Gibbs Sampling was...
