0.064). Genetic correlations between the direct and maternal
genetic effects within a trait were negative and
moderate (−0.219 ± 0.097 for CE, −0.337 ± 0.080 for
BrW, and −0.440 ± 0.102 for WW). Genetic correlations
for CED-BrWM and CED-WWM were −0.121 ± 0.090
and −0.097 ± 0.113, respectively. The genetic correlation
for CEM-CID was unfavorable (0.485 ± 0.078), and
those for CEM-BrWD (−0.094 ± 0.079) and CEM-WWD
(−0.125 ± 0.082) were low and negative. The genetic
correlation between CID and WWM was favorable
(−0.148 ± 0.106). Overall, the data presented here support
the hypothesis that maternal effects for CE and
BrW are not the same and that the genetic relationships
between CI and maternal effects for WW in beef cattle
follow a similar pattern to that reported between CI
and milk yield in dairy cattle. Moreover, the need to
include direct and maternal breeding values in beef
cattle selection programs is suggested.
