Strategies for single nucleotide polymorphism (SNP) genotyping to enhance genotype imputation in Gyr (Bos indicus) dairy cattle: Comparison of commercially available SNP chips. Author(s): BOISON, S. A.; SANTOS, D. J. A.; UTSONOMIYA, A. H. T.; CARVALHEIRO, R.; NEVES, H. H. R.; O'BRIEN, A. M. P.; GARCIA, J. F.; SÖLKNER, J.; SILVA, M. V. G. B. Genotype imputation is widely used as a cost-effective strategy in genomic evaluation of cattle. Key determinants of imputation accuracies, such as linkage disequilibrium patterns, marker densities, a... ... Repository: BDPA Publication year: 2015
Genome Wide Association Study for Calving Interval in Gyr Dairy Cattle. Author(s): MACHADO, M. A.; UTSUNOMIYA, A. T. H.; BOISON, S. A.; SANTOS, D. J. A. dos; UTSUNOMIYA, Y. T.; FONSECA, R. da; SÖLKNER, J.; GARCIA, J. F.; VERNEQUE, R. da S.; SILVA, M. V. G. B. Repository: BDPA Publication year: 2014
Genetic parameters of milk production in gyr dairy cattle (Bos indicus). Author(s): PACHECO, G. B.; NASCIMENTO, G. C.; PINHEIRO, R.; TEIXEIRA, R. B.; VERNEQUE, R. da S.; PANETTO, J. C. do C. An alternative to the adoption of 305-day milk yield during lactation to evaluate bovine genetics is the use of test-day milk yield (TDMY) information. This procedure has been used in the main cattle... ... Repository: BDPA Publication year: 2015
Descriptive analysis of copy number variation regions in a population of dairy Gyr cattle. Author(s): SILVA, M. V. G. B.; OLIVEIRA JUNIOR, G.; REY, F. S. B.; GIACHETTO, P. F.; MACHADO, M. A.; VERNEQUE, R. da S.; FERRAZ, J. B. S. The aim of this work was to investigate, based on a high density BovineHD SNP array, the abundance and distributions of CNVs and CNVR in a Gyr cattle population from Brazil. Genotype data of represent... ... Repository: BDPA Publication year: 2014
Common copy number variation regions affecting dairy traits in Gyr cattle. Author(s): OLIVEIRA JUNIOR, G. A.; CARMO, A. S.; UTSUNOMIYA, A. T. H.; CHUD, T. C. S.; REY, F. S. B.; FERRAZ, J. B. S.; SILVA, M. V. G. B. Repository: BDPA Publication year: 2015
Single nucleotide variants and InDels identified from whole-genome re-sequencing of Guzerat, Gyr, Girolando and Holstein cattle breeds. Author(s): STAFUZZA, N. B.; ZERLOTINI NETO, A.; LOBO, F. P.; YAMAGISHI, M. E. B.; CHUD, T. C. S.; CAETANO, A. R.; MUNARI, D. P.; GARRICK, D. J.; MACHADO, M. A.; MARTINS, M. F.; CARVALHO, M. R.; COLE, J. B.; SILVA, M. V. G. B. Whole-genome re-sequencing, alignment and annotation analyses were undertaken for 12 sires representing four important cattle breeds in Brazil: Guzerat (multi-purpose), Gyr, Girolando and Holstein (da... ...

Expressed sequenced tags profiling of resistant and susceptible Gyr x Holstein cattle infested with the tick Rhipicephalus (Boophilus) microplus. Author(s): NASCIMENTO, C. S.; MACHADO, M. A.; GUIMARÃES, S. E. F.; MARTINS, M. F.; PEIXOTO, J. de O.; FURLONG, J.; PRATA, M. C. de A.; VERNEQUE, R. da S.; TEODORO, R. L.; LOPES, P. S. Tick resistance in cattle is mainly found in zebu (Bos indicus) animals, although it is also present in some taurine (B. taurus) breeds. In order to characterize functional genes involved in tick resi... ... Repository: BDPA Publication year: 2011
Incorporation of lactations with non-conventional drying-off causes in genetic evaluation of Gyr dairy cattle. Author(s): REIS FILHO, J. C.; TORAL, F. L. B.; VERNEQUE, R. da S.; VERCESI FILHO, A. E.; TORRES, R. DE A.; EUCLYDES, R. F. Test-day records of milk yields from the first three lactations were used to verify consequences of incorporation of lactation with non-conventional drying-off causes in genetic evaluation of Gyr dair... ... Repository: BDPA Publication year: 2012
Differential expression of genes in resistant versus susceptible Gyr x Holstein cattle challenged with the tick Rhipicephalus (Boophilus) microplus. Author(s): NASCIMENTO, C. S. do; MACHADO, M. A.; GUIMARÃES, S. E. F.; GUIMARAES, M. F. M.; PEIXOTO, J. O.; FURLONG, J.; PRATA, M. C. de A.; VERNEQUE, R. da S.; TEODORO, R. L.; LOPES, P. S. The bovine tick Rhipicephalus (Boophilus) microplus causes major losses in cattle production systems in tropical regions. Bos indicus breeds are more resistant to ticks than B. taurus breeds. Resistan... ... Repository: BDPA Publication year: 2010
Assessment of runs of homozygosity islands and estimates of genomic inbreeding in Gyr (Bos indicus) dairy cattle. Author(s): PERIPOLLI, E.; STAFUZZA, N. B.; MUNARI, D. P.; LIMA, A. L. F.; IRGANG, R.; MACHADO, M. A.; PANETTO, J. C. do C.; VENTURA, R. V.; BALDI, F.; SILVA, M. V. G. B. Abstract BACKGROUND: Runs of homozygosity (ROH) are continuous homozygous segments of the DNA sequence. They have been applied to quantify individual autozygosity and used as a potential inbreeding me... ... Repository: BDPA Publication year: 2018
