Abstract
Two data sets were utilized to evaluate interaction between calf sex and calf genetic
type for preweaning performance of calves varying in percentage (0, 50, 100) Brahman
breeding. Data set I involved birth weight, preweaning average daily gain, and weaning
weight records on 3562 Angus (AA), Brahman ♂ × Angus ♀ (BA) and Brahman (BB) calves;
data set II consisted of birth weight, preweaning average daily gain and weaning weight
records on 3752 Hereford (HH), Brahman ♂ × Hereford ♀ (BH) and Brahman (BB) calves.
For both data sets, the calf sex × calf genetic type interaction was significant (P<0.01) except for preweaning average daily gain in data set II. In all cases, the
significant interactions were represented by a change in magnitude rather than a change
in rank for the two sexes of each calf genetic type. These results indicate that sex
differences are expected to be much greater for Brahman-sired BA and BH calves than
for calves of 0% (AA or HH) or 100% (BB) Brahman breeding. These increased sex differences
are of greatest importance for birth weight because of the relationship that exists
between birth weight and calving difficulty.
