Calfhood weights, body measurements and measures of fatness versus criteria of overall size and shape for predicting yearling performance in beef cattle



Calfhood weights, body measurements and measures of fatness versus criteria of overall size and shape for predicting yearling performance in beef cattle



Journal of Animal Science 63(2): 447-452



Data were collected over a 4-yr period on 223 Polled Hereford and 583 Aberdeen-Angus bulls and heifers at 2 locations. Variables recorded at weaning were age in days, body weight, visually assessed condition score, ultrasonically measured subcutaneous fat thickness, body length, heart girth and hip width. These variables were included in principal-component analyses. The 1st principal component of weaning variables was a measure of overall size, accounting for 66-69% of the total variation.
