Evaluation of an average numerator relationship matrix model and a Bayesian hierarchical model for growth traits in Nellore cattle with uncertain paternity
(Livestock Science, 2012-03-01) [Artigo]
The objective of this work was to compare a model based on the use of an average numerator relationship matrix (ANRM) and a hierarchical animal model (HIER) to indicate the most appropriate statistical procedure to better ...
Evaluation of TFAM and FABP4 gene polymorphisms in three lines of Nellore cattle selected for growth
(Genetics and Molecular Research, 2010-01-01) [Resumo]
We analyzed the polymorphisms TFAM HaeIII, TFAM MboI and FABP4 MspA1I in three Nellore lines selected for growth in order to evaluate how selection affects the frequencies of these polymorphisms and evaluate their association ...
Comparison of different nonlinear functions to describe Nelore cattle growth
(Journal of Animal Science, 2009-02-01) [Artigo]
This work aims to compare different nonlinear functions for describing the growth curves of Nelore females. The growth curve parameters, their (co) variance components, and environmental and genetic effects were estimated ...
MUC1 gene polymorphism in three Nelore lines selected for growth and its association with growth and carcass traits
(Molecular Biology Reports, 2012-02-01) [Artigo]
The objective of this study was to describe the VNTR polymorphism of the mucin 1 gene (MUC1) in three Nelore lines selected for yearling weight to determine whether allele and genotype frequencies of this polymorphism were ...
Genetic association between body composition measured by ultrasound and visual scores in Brazilian Nelore cattle
(Journal of Animal Science, 2012-12-01) [Artigo]
The objective of this study was to evaluate the genetic variability of body composition traits measured by ultrasound, growth traits, and visual scores as well as their genetic associations in Nelore cattle. A total of ...
Results of 23 years of selection for post-weaning weight in a Caracu beef herd
(South African Journal of Animal Science, 2008-01-01) [Artigo]
Data from 1 698 animals belonging to all experimental Caracu herd were analysed with the objective of calculating the Population selection differentials, generation intervals, effective size and inbreeding coefficients, ...
