Epigenética: mecanismos, herança e implicações no melhoramento animal. Author(s): PAIVA, J. T.; RESENDE, M. D. V. de; RESENDE, R. T.; OLIVEIRA, H. R.; SILVA, H. T.; CAETANO, G. C.; LOPES, P. S.; SILVA, F. F. A epigenética é definida como mudanças na expressão gênica que podem ser herdadas e que não alteram a sequência do DNA. Existem dois mecanismos epigenéticos principais, a metilação do DNA e a modifica... ... Repository: BDPA Publication year: 2019

F.; LOPES, P. S.; GUIMARÃES, S. E. F; SANTOS, G. G. dos; THOMPSON, G.; CARVALHEIRA, J. Repository: BDPA Publication year: 2018
Single-step genomic evaluation using an autoregressive multiple lactation model for Portuguese Holstein cattle. Author(s): SILVA, A. A.; SILVA, D. A.; GUIMARÃES, S. E. F.; LOPES. P. S.; SILVA, F. F.; THOMPSON, G.; COSTA, C. N.; CARVALHEIRA, J. Repository: BDPA Publication year: 2018
Regularized quantile regression for SNP marker estimation of pig growth curves. Author(s): BARROSO, L. M. A.; NASCIMENTO, M.; NASCIMENTO, A. C. C.; SILVA, F. F.; SERÃO, N. V. L.; CRUZ, C. D.; RESENDE, M. D. V. de; SILVA, F. L.; AZEVEDO, C. F.; LOPES, P. S.; GUIMARÃES, S. E. F. Background: Genomic growth curves are generally defined only in terms of population mean; an alternative approach that has not yet been exploited in genomic analyses of growth curves is the Quantile R... ...

Factor analysis applied to genome prediction for high-dimensional phenotypes in pigs. Author(s): TEIXEIRA, F. R. F.; NASCIMENTO, M.; NASCIMENTO, A. C. C.; SILVA, F. F. e; CRUZ, C. D.; AZEVEDO, C. F.; PAIXÃO, D. M.; BARROSO, L. M. A.; VERARDO, L. L.; RESENDE, M. D. V. de; GUIMARÃES, S. E. F.; LOPES, P. S. The aim of the present study was to propose and evaluate the use of factor analysis (FA) in obtaining latent variables (factors) that represent a set of pig traits simultaneously, for use in genome-wi... ...

Genomic prediction for additive and dominance effects of censored traits in pigs. Author(s): SANTOS, V. S.; MARTINS FILHO, S.; RESENDE, M. D. V. de; AZEVEDO, C. F.; LOPES, P. S.; GUIMARÃES, S. E. F.; SILVA, F. F. Age at the time of slaughter is a commonly used trait in animal breeding programs. Since studying this trait involves incomplete observations (censoring), analysis can be performed using survival mode... ... Repository: BDPA Publication year: 2016
Genomic selection for slaughter age in pigs using the Cox frailty model. Author(s): SANTOS, V. S.; MARTINS FILHO, S.; RESENDE, M. D. V. de; AZEVEDO, C. F.; LOPES, P. S.; GUIMARAES, S. E. F.; GLORIA, L. S.; SILVA, F. F. The aim of this study was to compare genomic selection methodologies using a linear mixed model and the Cox survival model. We used data from an F2 population of pigs, in which the response variable w... ... Repository: BDPA Publication year: 2015
Comparison of dimensionality reduction methods to predict genomic breeding values for carcass traits in pigs. Author(s): AZEVEDO, C. F.; NASCIMENTO, M.; SILVA, F. F.; RESENDE, M. D. V. de; LOPES, P. S.; GUIMARÃES, S. E. F.; GLÓRIA, L. S. A significant contribution of molecular genetics is the direct use of DNA information to identify genetically superior individuals. With this approach, genome-wide selection (GWS) can be used for this... ... Repository: BDPA Publication year: 2015
Correlation between PTA for milk and beef traits of Guzerá animals from dual-purpose herds in Brazil. Author(s): PEIXOTO, M. G. C. D.; CANDA, R. A.; BRUNELI, F. A. T.; SANTOS, G. G. dos; VENTURA, H. T.; LOPES, P. S. Repository: BDPA Publication year: 2014
