This study investigated the presence of antibodies and antibodiestiters against bovine herpesvirus type 1 (BoHV-1) in bovines at slaughter age in the ten planning regions of Goiás State. Blood samples (660) were collected in slaughterhouses under federal inspection and they were tested for neutralizing antibody by virus neutralization test. The results showed that 84.5% of serum samples were positive for BoHV-1, while the regionalized analysis found rates varying from 63.4% to 100%. This study revealed 36.3% of animals with high titers of neutralizing antibodies. The region surrounding Brasilia presented the highest percentage of animals with high titers (65.8%) and the Southeast Region of Goiás, the lowest (13.6%). The occurrence of high percentage of reagents with high antibody levels suggests the course of BoHV-1 active or reactivated infections among these animals.
