The Dollar Growth Index uses which benchmark to gauge a yearling's potential offspring value?

Herd Average Breed Average Market Price Historical Growth Rate

Correct Answer:

Breed Average

Explanation:

The Dollar Growth Index is measured against the breed average. It translates a yearling’s genetic potential for growth into a dollar value, using the breed’s typical performance as the baseline. By comparing to the breed average, you can see whether this animal’s offspring are expected to perform better or worse than the standard for its breed. A higher index means greater predicted offspring value, while a lower one suggests less. The breed average is used because it provides a consistent, breed-wide reference; herd averages are just one group, market price isn’t about genetics, and historical growth rate looks at past performance rather than current genetic merit relative to the breed.
