Genomic selection in multi-breed dairy cattle populations. Author(s): 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
Genetic parameters for milk production traits and breeding goals for Gir dairy cattle in Brazil. Author(s): PRATA, M. C. de A.; VERNEQUE, R. da S.; PEIXOTO, M. G. C. D. The present study defined breeding goals and proposed selection indices for milk production and quality traits of Gir dairy cattle. The results indicate that milk component traits should be included i... ... Repository: BDPA Publication year: 2015
Genetic analysis of productive and reproductive traits in multiple-breed dairy cattle populations. Author(s): SILVA, M. V. G. B.; PANETTO, J. C. do C. The objective of this work was to determine whether the random regression model using linear splines (RRMLS) is suitable to estimate the genetic parameters for productive and reproductive traits of a... ... Repository: BDPA Publication year: 2017
Prediction of free-stall occupancy rate in dairy cattle barns through fuzzy sets. Author(s): PIRES, M. de F. A. ABSTRACT - The goal of this study was to develop a fuzzy model to predict the occupancy rate of free-stalls facilities of dairy cattle, aiding to optimize the design of projects. The following input v... ... Repository: BDPA Publication year: 2013
Copy number variation in dairy cattle using next-generation sequencing. Author(s): CHUD, T. C. S.; BICKHART, D. M.; ZERLOTINI NETO, A.; COLE, J. B.; SILVA, M. V. G. B.; MUNARI, D. P. Gene copy number variants (CNV) have been shown to be associated with several production traits in dairy cattle; however, the detection and validation of CNVs in crossbred cattle is currently lacking.... ...

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
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): SILVA, M. V. G. B. 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.... ... Repository: BDPA Publication year: 2016
Ruminal methane emission by dairy cattle in southeast Brazil. Author(s): LIMA, M. A. de; FRIGHETTO, R. T. S. 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... ...
