Abstract

The objective of this study was to establish the frequency of infection and to analysis risk factors to Neospora caninum in calves and heifers from 18 dairy herds of Lavras, Minas Gerais State. Five hundred and thirty and four samples were screened by indirect immunofluorescence antibody test (IFAT) using cut off dilution of 1:200. The dairy herds were classified in two groups: group A) herds produced more than 1,000 lid of milk/day and group B) herds produced less than 1,000 lid of milk/day. The herd prevalence was 100% (18/18). The overall frequency of N. caninum infection was 46.25% (247/534) such as 43.66% (93/213) and 47.97% (154/321) in group A and B, respectivelly. There was no statistically significant difference between the groups (p>0.05). There was no significant association between risk factor and serology for N. caninum (p>0.05). The results indicate that the infection for N. caninum appears to be widespread between calves and heifers of dairy herds in microregion of the Lavras, south of Minas Gerais State.
