Genomic selection in multi-breed dairy cattle populations. Author(s): COLE, J. B.; SILVA, M. V. G. B. Abstract Genomic selection has been a valuable tool for increasing the rate of genetic improvement in purebred dairy cattle populations. However, there also are many large populations of crossbred dai... ... Repository: BDPA Publication year: 2016
Embryo biopsies for genomic selection in tropical dairy cattle. Author(s): OLIVEIRA, C. S.; CAMARGO, L. S. de A.; SILVA, M. V. G. B.; SARAIVA, N. Z.; QUINTAO, C. C. R.; MACHADO, M. A. Genomic selection has transformed the livestock industry, enabling early-life selection of animals. Biopsy sampling of pre-implantation embryos has been described since 1968. However, it was only afte... ... Repository: BDPA Publication year: 2023
Effect of pregnancy on the genetic evaluation of dairy cattle. Author(s): PEREIRA, R. J.; SANTANA JUNIOR, M. L.; BIGNARDI, A. B.; VERNEQUE, R. da S.; EL FARO, L.; ALBUQUERQUE, L. G. de We investigated the effect of stage of pregnancy on estimates of breeding values for milk yield and milk persistency in Gyr and Holstein dairy cattle in Brazil. Test-day milk yield records were analyz... ... Repository: BDPA Publication year: 2011
Physiological parameters for thermal stress in dairy cattle. Author(s): DALCIN, V. C.; FISCHER, V.; DALTRO, D. dos S.; ALFONZO, E. P. M.; STUMPF, M. T.; KOLLING, G. J.; SILVA, M. V. G. B.; McMANUS, C. The objective of this study was to investigate changes in physiological parameters of dairy cows and understand which physiological parameters show greater reliability for verification of heat stress.... ...

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
Ruminal methane emission by dairy cattle in southeast Brazil. Author(s): PEDREIRA, M. S.; PRIMAVESI, O.; LIMA, M. A. de; FRIGHETTO, R. T. S.; OLIVEIRA, S. G. de; BERCHIELLI, T. T. ABSTRACT: Ruminal gases, particularly methane, generated during the fermentative process in rumen, represent a partial loss of feed energy and are also pointed to as an important factors in greenhouse... ...

Ruminal methane emission by dairy cattle in Southeast Brazil. Author(s): PEDREIRA, M. dos S.; PRIMAVESI, O. M. A. S. P. R.; LIMA, M. A. de; FRIGHETTO, R. T. S.; OLIVEIRA, S. G. de; BERCHIELLI, T. T. Ruminal gases, particularly methane, generated during the fermentative process in rumen, represent a partial loss of feed energy and are also pointed to as an important factors in greenhouse effect. T... ... Repository: BDPA Publication year: 2009
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
Storage and recovery of dairy cattle genotype data from the data science approach. Author(s): SILVA, R.; ALMEIDA, F.; ARBEX, W. A. Repository: BDPA Publication year: 2015
Genetic parameters for milk production traits and breeding goals for Gir dairy cattle in Brazil. Author(s): PRATA, M. A.; EL FARO, L.; VERNEQUE, R. da S.; VERCESI FILHO, A. E.; PEIXOTO, M. G. C. D.; MOREIRA, E. L.; CARDOSO, V. L. Repository: BDPA Publication year: 2014
