Milk fatty acid characterization and genetic parameter estimates for milk conjugated linoleic acid in buffaloes
(Journal of Dairy Research, 2011-05-01) [Artigo]
The objectives of this study were to analyse buffalo milk fat composition, to verify the activity of Delta (9)-desaturase enzyme in the mammary gland, as well as to estimate additive genetic variances for milk, fat and ...
Genetic parameters for test-day yield of milk, fat and protein in buffaloes estimated by random regression models
(Journal of Dairy Research, 2012-08-01) [Artigo]
The test-day yields of milk, fat and protein were analysed from 1433 first lactations of buffaloes of the Murrah breed, daughters of 113 sires from 12 herds in the state of São Paulo, Brazil, born between 1985 and 2007. ...
Genetic parameter estimates for buffalo milk yield, milk quality and mozzarella production and Bayesian inference analysis of their relationships
(Genetics and Molecular Research, 2010-01-01) [Artigo]
Buffalo milk has excellent physical and chemical qualities as a consequence of the high percentage of constituents. This milk property is desirable for the dairy industry because it facilitates manufacture of mozzarella ...
Association between JY-1 gene polymorphisms and reproductive traits in beef cattle
(Gene, 2014-01-10) [Artigo]
Reproductive traits have a high economic value and it is interesting to include them in the selection objectives of an animal breeding program. These traits generally show low heritability and molecular markers may therefore ...
Copy number variation regions in Nellore cattle: Evidences of environment adaptation
(Livestock Science, 2018-01-01) [Artigo]
The aim of the present study was to analyze the distribution of CNV regions (CNVRs) as well as to address hypothesis about the natural/artificial selection process in Nellore cattle. A total of 399,361 CNVs were identified, ...
Association between single nucleotide polymorphisms and sexual precocity in Nellore heifers
(Animal Reproduction Science, 2017-02-01) [Artigo]
The aim of this study was to determine the extent (r2) of linkage disequilibrium (LD) in the genome of Nellore cattle, and to examine associations between single nucleotide polymorphisms (SNP) and age at first calving (AFC) ...
Erratum: Genome-wide association study of reproductive traits in Nellore heifers using Bayesian inference (Genetics Selection Evolution (2015) 47:67 DOI 10.1186/s12711-015-0146-0)
(Genetics Selection Evolution, 2015-09-17) [Errata]
Genomic prediction of breeding values for carcass traits in Nellore cattle
(Genetics Selection Evolution, 2016-01-29) [Artigo]
Background: The objective of this study was to evaluate the accuracy of genomic predictions for rib eye area (REA), backfat thickness (BFT), and hot carcass weight (HCW) in Nellore beef cattle from Brazilian commercial ...
Genome-wide scan reveals population stratification and footprints of recent selection in Nelore cattle
(Genetics Selection Evolution, 2018-05-02) [Artigo]
Background: This study aimed at (1) assessing the genomic stratification of experimental lines of Nelore cattle that have experienced different selection regimes for growth traits, and (2) identifying genomic regions that ...
Genomic prediction ability for beef fatty acid profile in Nelore cattle using different pseudo-phenotypes
(Journal of Applied Genetics, 2018-11-01) [Artigo]
The aim of the present study was to compare the predictive ability of SNP-BLUP model using different pseudo-phenotypes such as phenotype adjusted for fixed effects, estimated breeding value, and genomic estimated breeding ...
