Abstract

This study investigated the accuracy of estimated breeding values (EBV) over different training generations in layer chickens using pedigree and marker-based models. On average, the accuracy of EBV based on markers was higher than that based on pedigree. The accuracy of all methods increased with an increase in the number of generations in training data, but slightly dropped or remained even after including training generations far apart from validation.
