EPD stands for which term?

• A. expected progeny differences
• B. estimated production data
• C. enhanced progeny design
• D. electronic progeny details

Answer: (A)

EPD stands for expected progeny differences, a measure used in animal breeding to express the genetic advantage an animal is expected to pass to its offspring for a specific trait. It reflects the anticipated difference in performance of the progeny of an individual compared with the progeny of other animals in the population, assuming similar environments. This lets breeders compare animals on genetic merit rather than just on their own performance. The value is derived from performance records and pedigree data using statistical methods, and its accuracy grows as more offspring and related data are included.

The other phrases aren’t standard terms for this concept; they don’t represent the genetic merit estimate that EPD denotes, so they’re not used in the same way in breeding contexts.
