However, the meat industry has demanded products of higher quality. Nelore is an important bovine breed and well noted in Brazil for its meat production, body size and sturdiness. ![]() These NOR regions were repeated on the same chromosomes for the 4 animals studied. In this study we found more regions in chromosomes with staining than presented in the literature for the Bos indicus group (BIN). Ag-staining for nucleolus organizer regions (AgNOR) was identified on the telomeric end of the long arm in 7 autosomal chromosomes. G-banding presented the expected band pattern in the respective chromosome pairs in correspondence with the established chromosomal patterns for the species. C-banding revealed C-positive heterochromatin in centromeric regions almost in all chromosomes. The diploid chromosome number was invariably normal, 2n = 60. Chromosome banding techniques (C, G and NOR) revealed the karyotype architecture of Nelore cattle common with that of other breeds of zebu cattle formerly karyotyped. These samples were submitted to the cell culture method to study metaphase chromosomes. Blood samples were collected from the animals of the School of Agrarian and Biological Sciences of the Pontifical Catholic University of Goiás, two males and two females of pure breed. Chromosome banding techniques were applied and standardized to obtain karyotype characteristics for the first time in Brazil of Nelore cattle – Bos taurus indicus Linnaeus, 1758 – (bovine subspecies most prominent in Brazilian livestock). ![]()
