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.

The aim of this study was to describe the population structure of the registered Red Sindhi cattle in Brazil. Descriptive statistics of the distribution of the number of progeny are presented, and the generation interval and effective population size were estimated, using pedigree records of animals registered from 1955 to 1998. The observed generation interval for the whole time period was 7.65 yr, and for the period 1994-1998 it was 7.96 yr. The effective population size for the following periods (1979-83, 1984-88, 1989-93 and 1994-98) were, respectively, 501, 26, 20 and 19.
