Which of the following is a common EPD used to predict performance at weaning?

• A. Yearling height
• B. Weaning weight
• C. Calving interval
• D. Carcass yield

Answer: (B)

The main idea is using an Expected Progeny Difference that targets early growth to forecast how calves will perform at weaning. The weaning weight EPD estimates the genetic tendency for a calf to be heavier when it is weaned, making it the most direct predictor of performance at that specific time. Producers rely on this measure because weaning weight reflects early growth potential and is a practical benchmark for income and management decisions. Other options describe traits not tied to weaning weight: yearling height relates to later growth, calving interval is about reproductive efficiency, and carcass yield concerns post-slaughter. So the weaning weight EPD is the appropriate choice for predicting performance at weaning.
