Os modelos de regressão aleatória (MRA) aplicando funções B-spline são uma alternativa para modelar pesos do nascimento até a idade adulta dos animais, pois estas funções são menos vulneráveis as dificuldades constantemente observadas em ou

The objective was to compare models by Bayes factor (BF) to estimate the (co)variance compo- nents, genetic parameters and genetic values for the adjusted weights at 205 (W205), 365 (W365) and 550 (W550) days of age in Tabapuã animals reared on past
