Strategic control of cattle ticks: milk producers' perceptions. Repositório: BDPA Ano de publicação: 2011
Polymorphisms in genes coding milk proteins and protein hormones involved in milk production traits in Brazilian Guzerá cattle. 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... ...

Genetic parameters for milk production traits and breeding goals for Gir dairy cattle in Brazil. 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... ... Repositório: BDPA Ano de publicação: 2015
Genetic parameters of milk production in gyr dairy cattle (Bos indicus). 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... ... Repositório: BDPA Ano de publicação: 2015
Candidate genes for milk, growth and immune system traits in Brazilian Iberian: derived Locally Adapted cattle breeds. Along decades of breeding in a variable ecosystem throughout the country, the first taurine animals arrived in Brazil became adapted to a wide range of environments with different levels of improved f... ...

Cluster analysis of breeding values for milk yield and lactation persistency in Guzerá cattle. 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... ... Repositório: BDPA Ano de publicação: 2016
Genetic Parameters for Milk Yield and Lactation Persistency Using Random Regression Models in Girolando Cattle. Repositório: BDPA Ano de publicação: 2015
Genetic trend estimates for milk yield production and fertility traits of the Girolando cattle in Brazil. Annual genetic trends and selection differentials for 305-day milk yield (305MY), age at first calving (AFC), and first calving interval (FCI) were estimated by four selection paths [sires of bulls (S... ... Repositório: BDPA Ano de publicação: 2016
National Breeding Program of Guzerá Cattle for Milk: progeny testing, National Zootechnical Archive and MOET nucleus results. 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... ... Repositório: BDPA Ano de publicação: 2021
The contribution of a MOET nucleus scheme for the improvement of Guzerá ( Bos indicus) cattle for milk traits in Brazil. The Guzerá breed evolved from the introduction of breeds from India, mainly the Kankrej breed, into Brazilian livestock at the end of the 19th century. Guzerá adapted well to the climatic conditions o... ... Repositório: BDPA Ano de publicação: 2022
