[en] Weight records from Simmental beef cattle provided by the Associação Brasileira dos Criadores das Raças Simental e Simbrasil (ABCRSS) were used in genetic parameters estimation by with (RRM2) or without inclusion (RRM1) of animals from the technique of embryo transfer (ET). A model with order three for the fixed curve and random effects (direct additive genetic, maternal additive genetic, maternal permanent environment and direct permanent environment) was used. The direct heritabilities in RRM1 and RRM2 showed the same behavior with oscillations along the growth curve and were slightly higher in RRM1, ranging around 0.1 to 0.5, and in RRM2 ranged among 0.1 and 0.4. These results suggest that the inclusion of animals from the technique of embryo transfer can be done using random regression models, inasmuch would provide potential accuracy gains and greater genetic gains per unit time.
