%X reproductive traits were evaluated in this fourth article of the serie related to the brahman herd located at la cumaca £¿al¨ª benavides zapata£¿ experimental station, in yaracuy state, venezuela. information from 2180 females borned between 1970 to 2002 was analyzed by mixed model techniques using an animal model in order to obtain heritability estimates for pregnancy in heifers (pn), interval between first day of service season to first calving (iip), survival up to six years of age (s6), number of calves up to six years of age (nh6) and total kilograms of weaned calves up to six years of age (kd6). with exception of kd6, heritability estimates were less than 0.09. maximum value obtained was 0.11 for kd6. results showed that traits considered in this paper are not of relevant importance, from the genetic point of view,£¿ in a beef cattle selection program.
