Comparison between multiple-trait and random regression models for genetic evaluation of weight traits in Australian meat sheep.

Journal of animal science - 3 Jan 2024

Paneru Uddhav, Moghaddar Nasir, van der Werf Julius

Abstract excerpt

Random regression (RR) models are recommended as an alternative to multiple-trait (MT) models for better capturing the variance-covariance structure over a trajectory and hence more accurate genetic evaluation of traits that are repeatedly measured and genetically change gradually over time. However, a limited number of studies have been done to empirically compare RR over a MT model to determine how much extra...
