Abstract
Canadian Record of Performance for Beef Cattle data were used to estimate genetic, environmental and phenotypic correlations between pairs of four calf growth traits: weaning weight, preweaning average daily gain (ADG), yearling weight and postweaning ADG. A total of 61,688 Hereford and 22,333 Aberdeen Angus records were studied. Average genetic, environmental and phenotypic correlation estimates, in that order, for the following growth trait combinations were:.997,.974 and.979 for weaning weight and preweaning ADG;.801,.709 and.726 for weaning weight and yearling weight;.784,.692 and.706 for preweaning ADG and yearling weight;.516, −.143 and.104 for weaning weight and postweaning ADG;.494, −.142 and.094 for preweaning ADG and postweaning ADG; and.875,.595 and.741 for yearling weight and postweaning ADG.Keywords
