National genomic evaluation for a novel functional longevity trait.

Abstract excerpt

BACKGROUND: Cow longevity plays a major role in beef cattle industry profitability, reflecting the female's ability to remain productive in the herd. In this context, longitudinal models as random regression models (RRM) are the preferred method for genetic evaluation as they account for genetic and environmental effects over time. Traditionally, RRM longevity evaluations use binary phenotypes; however,...
