Genomic Prediction Ability Using Linear and Threshold Approaches for Different Stayability Definitions in Nellore Females

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 457-464, May 2026.
ABSTRACT Enhancing female longevity through regular calvings improves herd replacement rates and reduces the costs associated with replacing low reproductive efficiency animals. Stayability (STAY), defined as a cow's ability to remain productive in the herd, is a categorical trait that challenges traditional genetic evaluation due to its non‐normal ...
