Quantifying individual variation in reaction norms using random regression models fitted through Legendre polynomials: application in eucalyptus breeding. Author(s): ALVES, R. S.; RESENDE, M. D. V. de; ROCHA, J. R. do A. S. de C.; PEIXOTO, M. A.; TEODORO, P. E.; SILVA, F. F. e; BHERING, L. L.; SANTOS, G. A. dos An accurate, efficient and informative statistical method for analyses of genotype × environment (G × E) interactions is a key requirement for progress in any breeding program. Thus, the objective of... ... Repository: BDPA Publication year: 2020
Genetic parameters for test day milk yield of first lactation Holstein cows estimated by randon regression using Legendre polynomials. Author(s): COSTA, C. N.; MELO, C. M. R.; PACKER, I. U.; FREITAS, A. F.; TEIXEIRA, N. M.; COBUCCI, J. A. Data comprising 263,390 test-day (TD) records of 32,448 first parity cows calving in 467 herds between 1991 and 2001 from the Brazilian Holstein Association were used to estimate genetic and permanent... ...

F.; MARTINS FILHO, R.; MALHADO, C. H. M.; AZEVEDO, D. M. M. R.; SANTOS, K. R. dos; SOUSA JÚNIOR, S, C, de B-spline functions have been used in random regression models (RRM) to model animal weight from birth to adulthood because they are less vulnerable to common difficulties of other methods. However, it... ... Repository: BDPA Publication year: 2021
Estimation of genetic parameters for test-day milk yield in Girolando cows using a random regression model. Author(s): SANTOS, E. P. B.; FELTES, G. L.; NEGRI, R.; COBUCI, J. A.; SILVA, M. V. G. B. The objective of this study was to estimate the components of variance and genetic parameters of test-day milk yield in first lactation Girolando cows, using a random regression model. A total of 126,... ... Repository: BDPA Publication year: 2021
