Modeling enteric methane emission from beef cattle in Brazil: a proposed equation performed by principal component analysis and mixed modeling multiple regression. Author(s): MEDEIROS, S. R. de; BARIONI, L. G.; BERNDT, A.; FREUA, M. C.; ALBERTINI, T. Z.; COSTA JUNIOR, C.; FELTRIN, G. B. Brazil has the largest commercial beef cattle herd in the world but does not have its own model to predict methane (CH4 ) emission. The aim of this study was to create the first empirical enteric CH4... ... Repository: BDPA Publication year: 2014
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.
