Abstract

The economic impact caused by Neospora caninum in beef cattle is not clear, the most relevant disturbance is the abortion, which is provoked by this parasite, therefore the identification of the disease etiology is important in order to determine measure of prevention and control. The objective of this study was to find out the occurrence of N. caninum in beef cattle and in farm dogs from Avaré region, the importance of the presence of dogs in farms and its relation to the number of cattle and winter food supplementation. It was collected 777 samples of beef cattle sera and 39 samples of dog sera, which lived with this cows in eight farms, and these sera were submitted to indirect fluorescent antibody test. Anti-N. caninum antibodies were detected in 15.57% (121/777) of the beef cattle, at dilutions from 1:200 to 1:3200, and 58.97% (23/39) of the dogs at dilutions from 1:50 to 1:400. The occurrence of antibodies have no relation to absence of dogs in two farm, however, the rate of the infected beef cattle were lower in farm with lower number of cattle per hectare. The winter food supplement have no influence in the presence of antibodies anti-N. caninum in the herd.
