Yearling Heifer Frame Score and Mature Cow Size in the Angus Breed

---

Abstract

Obtaining a frame score on yearling heifers provides one opportunity to develop uniformity in the commercial cow herd. A total of 4,023 records were available from the American Angus Association’s mature cow size database to investigate the yearling frame score and mature size relationship. For every unit increase in frame score, mature height will be increased around 1.6 inches, and mature weight will be increased by about 83 lbs. Knowing the relationship between a yearling frame score measurement and actual mature size should assist producers in better defining the frame score that will fit within their specific environment and feed resources.
