What is a selection index, and does Choice use them in its genetic program?

Yes, Choice uses Selection Indexes in all of its lines, and has a unique index for each line. A selection index is a way to improve many traits at the same time by accounting for each traits economic importance as well as it’s genetic component and the interactions between all of the traits. Our goal is to include all of the economically important traits for a given line in the index with the proper amount of emphasis.
