Body weight, withers height, body length and chest girth were measured at 3-mth intervals between birth and 36 mth of age in Korean Black (KB), Brahman and Santa Gertrudis (SG) cattle, and in 2- and 3-breed crosses between these breeds. In 2-breed crosses, additive effects for all 4 traits were >90%, and non-additive effects were <10% (specific combining ability). Similar results were obtained in 3-breed crosses, with non-additive effects being <5% and maternal effects <10% for all traits. [For Pt. 1 see ABA 47, 58].
