Use of progeny testing in beef cattle: Prediction of genetic gain in a Nelore Cattle Breeding Program
(1995-01-01)
Genetic gains predicted for selection, based on both individual performance and progeny testing, were compared to provide information to be used in implementation of progeny testing for a Nelore cattle breeding program. ...

GENETIC PARAMETERS AND GENETIC TRENDS FOR TESTICULAR GROWTH AND REPRODUCTIVE TRAITS IN GUZERA CATTLE
(Univ Fed Rural Semi-arido-ufersa, 2015-01-01)
This study aimed to estimate genetic parameters and genetic trends for reproductive traits and testicular growth in Guzera cattle. Variance components were estimated through two-trait analyses using the restricted maximum ...
Inclusion of genomic information in estimation of genetic parameters for body weights and visual scores in Nelore cattle
(2021-01-01)
The aim of this study was to evaluate genomic information inclusion in genetic parameter estimation of standardized body weight at birth and at 240, 365, and 450 days of age, and visual scores for body structure, precocity, ...
GENETIC PARAMETERS FOR GESTATION LENGTH AND PRE- AND POSTWEANING GROWTH TRAITS IN NELLORE CATTLE
(Inst Zootecnia, 2015-01-01)
The objective of this study was to estimate heritabilities and genetic and phenotypic correlations for gestation length as calf trait (GLcalf) and preweaning [birth weight (BW) and weights at 120 (W120) and 210 (W210) days] ...
Genetic characterization of Colombian Brahman cattle using microsatellites markers
(Springer, 2013-07)
Genetic structure and diversity of 3789 animals of the Brahman breed from 23 Colombian regions were assessed. Considering the Brahman Zebu cattle as a single population, the multilocus test based on the HW equilibrium, ...
Trends of the genetic connectedness measures among Nelore beef cattle herds
(Wiley-Blackwell, 2012-02-01)
Validity of comparisons between expected breeding values obtained from best linear unbiased prediction procedures in genetic evaluations is dependent on genetic connectedness among herds. Different cattle breeding programmes ...
