Abstract
Genetic parameters for weights and heights of mature cows were estimated using a repeatability model from field data provided by the American Angus Association. The results showed that the heritabilities of both traits were large, and correlations between them were positive and strong. Selection on either trait should easily produce a response, and changing one should lead to a correlated response in the other. Genetic trend was generally for increasing cow weight over the last 25 years.
