An important goal in animal breeding is to improve longitudinal traits; that is, traits recorded
multiple times during an individual's lifetime or physiological cycle. Longitudinal traits were …

The objective of the present study was to compare a random regression model, usually used
in genetic analyses of longitudinal data, with the structured antedependence (SAD) model to …

The objective of this work was to compare genetic evaluations of milk yield in the Gir breed,
in terms of breeding values and their accuracy, using a random regression model applied to …

This study aimed to identify genomic regions influencing growth traits in Nellore cattle and
evaluate the predictive ability of each trait based on results obtained from single-step …

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 …

The objective of this study was to estimate (co) variance components and genetic
parameters for live weight (LW) and daily live weight gain (LWG) of Nellore bulls in a test …

Simple Summary Improving the genetic traits influencing rooster semen quality and quantity
is crucial for optimizing poultry production. Breeders can identify heritable traits that …

The objective of this study was to estimate variance components and genetic parameters for
accumulated 305-day milk yield (MY305) over multiple ages, from 24 to 120 months of age …

Growth traits in indigenous cattle are desirable economic parameters which should be
improved and their trends monitored over time to investigate direction of change. Traits …

The objective of this paper was to study the estimated breeding values (EBV) profiles for
feed conversion ratio (FCR) over the growing period in eight generations of divergent …
