[en] Weight records from Simmental cattle provided by the Associação Brasileira dos Criadores das Raças Simental e Simbrasil (ABCRSS) were used in genetic parameters estimation by with (MTM2) or without (MTM1) inclusion of animals from the embryo transfer technique (ET). The genetic parameters were estimated by restrict maximum likelihood (REML). The direct heritabilities (h2d) in MTM1 were 0.04, 0.11, 0.20, 0.27, 0.31, 0.42, and in MTM2 were 0.11, 0.11, 0.17, 0.21, 0.22 and 0.26, respectively, for ages at 100, 205, 365, 450, 550 and 730 days. The inclusion of animals from the technique of embryo transfer can result in potential accuracy gains in genetic evaluations and more genetic gains because of the reduction of the generation interval
