The aim of this study was to estimate variance and covariance components for gestation
length (GL), birth weight (BW), weaning weight (WW), and accumulated productivity (ACP) …

Principal component analysis was applied to evaluate the variability and relationships
among univariate breeding values predicted for 9 weaning and yearling traits, as well as …

Background Beef cattle breeding programs in Brazil have placed greater emphasis on the
genomic study of reproductive traits of males and females due to their economic importance …

The female reproductive performance, productivity and size are strongly associated with
production efficiency of herds raised in a tropical environment. The age at first calving (AFC) …

This study estimated the genetic variability and correlations between growth and
reproductive traits in Nelore cattle. Annual genetic changes in female reproductive traits …

Genealogy and productive information of 48621 dual-purpose buffaloes born in Colombia
between years 1996 and 2014 was used. The following traits were assessed using one-trait …

The objectives of this study were to estimate genetic parameters for accumulated egg
production over 3-wk periods and for total egg production over 54 wk of egg-laying, and …

A multitrait model (MC) and 5 reduced-rank models with principal component structure
(components PC1, PC1: 2, PC1: 3, PC1: 4, and PC1: 5) were compared. The objectives …

Assessing dominance and additive effects of casein complex single-nucleotide
polymorphisms (SNPs)(αS1, αS2, β, and κ casein), and their epistatic relationships may …

This research evaluated a multivariate approach as an alternative tool for the purpose of
