“…In the current study, sex had a significant effect on WW and YW traits (P<0.01). Schiermiester et al (2015) also reported a significant sex effect on these traits in a composite population represented by purebred Angus, Hereford, Red Angus, Charolais, Gelbvieh, Simmental, Limousin, and Composite MARC III (1/4 Angus, 1/4 Hereford , 1/4 Pinzgauer, 1/4 Red Poll), corroborating the results found by Alencar et al (2009) and Fialho et al (2015), who evaluated crossbred animals created by crossing Angus × Nelore and Simmental × Nelore cows and Angus, Bonsmara, and Canchim bulls; and purebred and crossbred calves derived from Nellore, Brangus, Wagyu, and ½ Brangus × ½ Nellore cows, crossed with bulls of the Aberdeen Angus, Red Angus, Brangus, Nellore, and Wagyu breeds, respectively.…”
