Abstract
Angus, Charolais and Herefords were mated to produce straightbred and all possible reciprocal two-breed crosses. This study included 812 calves in the analysis of heterosis effects on preweaning gain, adjusted 205-day weight, 205-day weight/metabolic cow weight and weaning score. The main effects of bull breed, cow breed and year exerted a significant influence on most of the weaning traits for both male and female calves.
