The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

Brazil is an important world leader in animal yield, but to maintain this status, needs to invest heavily in research to increase animal productivity. For Animal Breeding purpose, Brazil has many groups that develop important studies. Those studies ranging from estimating components of variation and genetic parameters, statistical modeling, and molecular markers applied to animal breeding. Thus, this review aims to summarize the research in animal breeding in Brazil through the first decade of the 21st century, which can indicate the progress and new challenges.
