Genetic parameters of milk production in gyr dairy cattle (Bos indicus). Author(s): PACHECO, G. B.; NASCIMENTO, G. C.; PINHEIRO, R.; TEIXEIRA, R. B.; VERNEQUE, R. da S.; PANETTO, J. C. do C. An alternative to the adoption of 305-day milk yield during lactation to evaluate bovine genetics is the use of test-day milk yield (TDMY) information. This procedure has been used in the main cattle... ... Repository: BDPA Publication year: 2015
Genetic association of variations in the kappa-casein and beta-lactoglobulin genes with milk traits in girolando cattle. Author(s): BARBOSA, S. B. P.; ARAÚJO, Í. I. M. DE; MARTINS, M. F.; SILVA, E. C. DA; JACOPINI, L. A.; BATISTA, Â. M. V.; SILVA, M. V. G. B. ABSTRACT - In dairy farm animals, one the most important goal of the selection is the improvement of milk yield and composition. Several studies have demonstrated that the candidate genes of the kappa... ... Repository: BDPA Publication year: 2019
Polymorphisms in genes coding milk proteins and protein hormones involved in milk production traits in Brazilian Guzerá cattle. Author(s): STEINBERG, R. S.; CARVALHO, M. R. S.; ROSSE, I. C.; MACHADO, M. A.; PEIXOTO, M. G. C. D. Research on genes affecting phenotypic variation in milk production and composition from indicine (Bos indicus) cattle is imperative, since these breeds are important tropical genetic resources, and t... ...

Strategic control of cattle ticks: milk producers' perceptions. Author(s): AMARAL, M A. Z. do; ROCHA, C. M. B. M. da; FACCINI, J. L.; FURLONG, J.; MONTEIRO, C. M. de O.; PRATA, M. C. de A. Repository: BDPA Publication year: 2011
Genetic parameters for milk production traits and breeding goals for Gir dairy cattle in Brazil. Author(s): PRATA, M. C. de A.; EL FARO, L.; VERNEQUE, R. da S.; VERCESI FILHO, A. E.; PEIXOTO, M. G. C. D.; MOREIRA, E. L.; CARDOSO, V. L. 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
National Breeding Program of Guzerá Cattle for Milk: progeny testing, National Zootechnical Archive and MOET nucleus results. Author(s): BRUNELI, F. A. T.; PEIXOTO, M. G. C. D.; SANTANA JÚNIOR, M. L.; PEREIRA, R. J.; ARBEX, W. A.; PENNA, V. M.; ZADRA, L. E. F.; VERNEQUE, R. da S.; LÔBO, R. B.; CARVALHO, M. R. S. Since Guzera is a dual-purpose breed, both the MOET Nucleus and various partner herds of the dairy breeding program also participate in the Genetic Evaluation Program of the Guzera Breed for Beef Prod... ...

Cluster analysis of breeding values for milk yield and lactation persistency in Guzerá cattle. Author(s): CRUZ, D. A. C. da; SAVEGNAGO, R. P.; SANTANA, A. B. B.; PEIXOTO, M. G. C. D.; BRUNELI, F. A. T.; FARO, L. El ABSTRACT - The aim of this study was to explore the pattern of genetic lactation curves of Guzerá cattle using cluster analysis. Test-day milk yields of 5,274 first-lactation Guzerá cows were recorded... ... Repository: BDPA Publication year: 2016
Economic values for milk production and quality traits of Guzerá cattle in Brazil. Author(s): LIGORI, V. A.; CARDOSO, V. L.; PEIXOTO, M. G. C. D.; BRUNELI, F. A. T.; ZADRA, L. E. F. Repository: BDPA Publication year: 2021
Heterogeneity of variance and genetic parameters for milk production in cattle, using Bayesian inference. Author(s): CAMARGO JUNIOR, R. N. C.; FERNANDES, L. da S.; PANETTO, J. C. do C.; SILVA, M. V. G. B.; ARAUJO, C. V. de; SILVA, A. G. M. e; MARQUES, J. R. F.; SILVA, W. C. da; ARAUJO, S. I. de; CASTRO, S. R. S. de; SILVA, L. K. X.; CASTRO, S. V.; LOURENÇO JUNIOR, J. de B. The goal of this study was to verify the effect of heterogeneity of variance (HV) on milk production in up to 305 days of lactation (L305) of daughters of Girolando, Gir and Holstein sires, as well as... ... Repository: BDPA Publication year: 2023
The A2 milk as an upgrading strategy in the cattle global value chain in Brazil. Author(s): POLASTRINI, A.; RODRIGUES, W.; PEDROZA FILHO, M. X. The objective of this study was to evaluate the potential of the A2 milk as an upgrading strategy for milk producers in Brazil. The primary data were obtained through semi-structured interviews with e... ... Repository: BDPA Publication year: 2022
