ABSTRACT: This research aimed to determine incidence of Toxoplama gondii infection in Corriedale sheep in southern Brazil during pregnancy and the extent of associated losses. Blood samples were collected from 411 Corriedale sheep in two flocks at different locations in the state of Rio Grande do Sul (Brazil). Presence of T. gondii was diagnosed by the Indirect Fluorescent Antibody Technique (IFAT). Seroprevalence of T. gondii during pre-mating was 20.2%, with no significant difference between the two flocks studied. Infection by T. gondii was influenced by ewes'age (P≤0.05). The pre-mating seroprevalence did not influence either returning to estrus or pregnancy rates. Weaning rate was significantly higher in pre-positive dams compared to negative...
