In an experiment involving 360 calves, heterosis and related effects were estimated for preweaning and post-weaning growth traits. Clear evidence of heterosis was found in both phases of growth. The percentage of heterosis ranged from 4.80 for birth weight to 13.73 for post-weaning gain. Heterosis in Brahman x Santa Gertrudis and Brahman x Criollo crosses indicated probable specific-combining ability.
