Growth curves of carcass traits obtained by ultrasonography in three lines of Nellore cattle selected for body weight

C. C. Coutinho, Mercadante, M. E. Z., Jorge, A. M., Paz, C. C. P., L. Faro, E., and Monteiro, F. M., Growth curves of carcass traits obtained by ultrasonography in three lines of Nellore cattle selected for body weight, vol. 14, pp. 14076-14087, 2015.

The effect of selection for postweaning weight was evaluated within the growth curve parameters for both growth and carcass traits. Records of 2404 Nellore animals from three selection lines were analyzed: two selection lines for high postweaning weight, selection (NeS) and traditional (NeT); and a control line (NeC) in which animals were selected for postweaning weight close to the average.
