Abstract

Bovine viral diarrhea virus (BVDV) is characterized as one of the main pathogens that promote significant losses to cattle and dairy cattle around the world and is therefore considered one of the most important viruses that affect cattle. BVDV infection can result in wide variability of clinical syndromes including reproductive, respiratory or digestive disease, occurs in many cattle herds causing economic losses without arousing any suspicion of the owner or the veterinarian. The present study aimed to verify the occurrence of bovine viral diarrhea virus infection in beef cattle for slaughter in a slaughterhouse under federal inspection in the state of Maranhão. Blood samples were collected from three hundred and sixty-eight female cattle in a slaughterhouse under federal inspection located in the city of Timon in the state of Maranhão. Among the obtained results 65% (239) samples were reagents for BVDV. Based on the results it can be concluded that there are antibodies to the bovine viral diarrhea virus in the evaluated herds.
