Records of 1021 Nelore cows were analyzed in order to evaluate the effect of selection for growth on their stayability in the herd up to five years, considering that they were selected (P5|S). The coded variable (0=culled and 1=not culled) was analyzed with a threshold model. The Nelore cows were born from 1981 to 1997 within the selected (NeS and NeT) and control (NeC) lines of the Experimental Station of Sertãozinho (SP-Brazil). In NeS and NeT the selected (replacement) animals […]
