 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,... ... |
 Author(s): FREITAS, L. S.; SILVA, M. A.; VERNEQUE, R. da S.; SANTOS, G. G.; CORRÊA, G. S.; VALENTE, B. D.; PEIXOTO, M. G. C. D.; VENTURA, R. V.

 Author(s): AZEVEDO JUNIOR, J.; GONÇALVES, T. de M.; SOUZA, J. C. de; RODRIGUEZ, M. A. P.; COSTA, C. N.; CARVALHEIRA, J. G. V. Abstract Random regression models (RRM) differ in terms of the functions used to describe the shape of lactation curves. The aim was to compare random regression models under different functions to de... ... |
 Author(s): JUNQUEIRA, R. P.; SANTANA JR, M. L.; LOPES, P. S.; VERNEQUE, R. da S.; LAGROTTA, M. R.; TORRES, R. DE A.; PEIXOTO, M. G. C. D. Com o objetivo de comparar modelos de regressão aleatória para a produção de leite no dia do controle (PLDC), foram utilizados 27.000 registros de PLDC de 3.362 primeiras lactações de vacas Gir Leitei... ... |
 Author(s): MELO, C. M. R. de; PACKER, I. U.; COSTA, C. N.; MACHADO, P. F. Covariance components for test day milk yield using 263 390 first lactation records of 32 448 Holstein cows were estimated using random regression animal models by restricted maximum likelihood. Three... ... |
 Author(s): COBUCI, J. A.; EUCLYDES, R. F.; COSTA, C. N.; TORRES, R. de A.; LOPES, P. S.; PEREIRA, C. S. A model for analyzing test day records including both fixed and random coefficients was applied to the genetic evaluation of first lactation data for Holstein cows. Data comprising 87045 test-day milk... ... |
 Author(s): COBUCI, J. A.; EUCLYDES, R. F.; LOPES, P. S.; COSTA, C. N.; TORRES, R. de A.; PEREIRA, C. S. Test-day milk yield records of 11,023 first-parity Holstein cows were used to estimate genetic parameters for milk yield during different lactation periods. (Co)variance components were estimated usin... ... |
 Author(s): DALTRO, D. dos S.; SILVA, M. V. G. B.; GAMA, L. T. da; MACHADO, J. D.; KERN, E. L.; CAMPOS, G. S.; PANETTO, J. C. do C.; COBUCI, J. A. The objective of this work was to evaluate the effects of breed and heterosis on the estimates of genetic parameters of 305-day milk yield (305MY), by fitting milk yield data to the Wood, Mixed Log, M... ... |
 Author(s): DALTRO, D. dos S.; PADILHA, A. H.; GAMA, L. T. da; SILVA, M. V. G. B.; COBUCI, J. A. The objective of this study was to estimate the breed, heterosis, and recombination effects on different components of the lactation curve of Girolando cattle. The dataset used consisted of 12,121 pur... ... |
 Author(s): MENEZES, G. R. de O.; TORRES, R. de A.; SARMENTO, J. L. R.; RODRIGUES, M. T.; BRITO, L. F.; LOPES, P. S.; SILVA, F. G. da Foram utilizados 10.238 registros semanais de produção de leite no dia do controle leiteiro provenientes de 388 primeiras lactações de cabras da raça Saanen visando comparar diferentes modelos de regr... ... |
