Which of the following defines EPD?

Expected Progeny Difference, often abbreviated as EPD, is a critical tool used in livestock selection and breeding. It quantifies the expected genetic contribution of an individual parent to its offspring's performance for specific traits. EPDs allow breeders to make informed decisions when selecting breeding stock based on expected genetic improvement in traits such as growth rate, reproductive performance, and overall productivity.

The use of EPDs is essential in improving livestock genetics, as it provides an estimate of how future offspring will perform compared to the average of the population. By relying on EPDs, livestock breeders can select for desirable traits while minimizing the risk of negative genetic variance, ultimately leading to more productive and efficient livestock. This concept is foundational in animal husbandry and helps ensure that breeding goals align with the overall objectives of the livestock operation.
