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... ...

Estimation of (co)variance components and genetic parameters for weights of red-winged tinamou using random regression models. Author(s): THOLON, P.; QUEIROZ, S. A. The objective of this work was to determine genetic parameters for body weight of tinamou in captivity. It was used random regression models in analyses of data by considering the direct additive gene... ... Repository: BDPA Publication year: 2011
Genetic parameters for milk production by using random regression models with different alternatives of fixed regression modeling. Author(s): COBUCI, J. A.; COSTA, C. N.; BRACCINI NETO, J.; FREITAS, A. F. de Records of test-day milk yields of the first three lactations of 25,500 Holstein cows were used to estimate genetic parameters for milk yield by using two alternatives of definition of fixed regressio... ...

Random regression models are suitable to substitute the traditional 305-day lactation model in genetic evaluations of holstein cattle in Brazil. Author(s): PADILHA, A. H.; COBUCI, J.; COSTA, C. N.; BRACCINI NETO, J. The aim of this study was to compare two random regression models (RRM) fitted by fourth (RRM4) and fifth-order Legendre polynomials (RRM5) with a lactation model (LM) for evaluating Holstein cattle i... ...

Persistency of lactation using random regression models and different fixed regression modeling approaches. Author(s): COBUCI, J. A.; COSTA, C. N. Milk yield test-day records on the first three lactations of 25,500 Holstein cows were used to estimate genetic parameters and predict breeding values for nine measures of persistency and 305-d milk y... ...

E. R. de; CAVALCANTE NETO, A.; DO Ó, A. O. Utilizaram-se 17.767 registros de pesos de 4.210 cordeiros da raça Santa Inês com o objetivo de avaliar a importância da inclusão do efeito materno nos modelos de estimação de componentes de (Co) vari... ...

Random regression models for the estimation of genetic and environmental covariance functions for growth traits in Santa Ines sheep. Author(s): SARMENTO, J. L. R.; TORRES, R. A.; SOUSA, W. H.; LOBO, R. N. B.; ALBUQUERQUE, L. G.; LOPES, P. S.; SANTOS, N. P. S.; BIGNARD, A. B. Abstract: Polynomial functions of different orders were used to model random effects associated with weight of Santa Ines sheep from birth to 196 days. Fixed effects included in the models were contem... ... Repository: BDPA Publication year: 2016
