We aimed to estimate genetic parameters for 305-d milk yield (MY305), growth (weaning – WW, yearling – YW and long yearling weights - LYW) and reproductive (age at first calving - AFC) traits in Guzerá cattle by using Bayesian multi-trait models and compare methodologies for handling censored data of age at first calving by Bayesian models. Data were provided by Brazilian Association of Zebu Cattle (ABCZ) and Embrapa Dairy Cattle Research Unit in partnership with the Brazilian Center of Guzerá Genetic Improvement (CBMG 2 ). The pedigree file (120,599 animals) included animals with phenotypic records and their known ancestors. Censored records were defined as AFC records out of range of 740 and 1860 days. Data including 69,157 AFC records we...
