Resumo: | A labelled avidin-biotin ELISA (lab-ELISA) using repeated serum samples of goats showed a progressive seroconversion with higher seroconversion rate at the period going from the beginning of the breeding up to the last half of lactation (35.0%), compared to that recorded at the beginning of breeding (17.8%)(p&lt;0.05). Furthermore, the seroreactivity pattern, evaluated by a lab-ELISA standard-curve with serum samples collected at 30-40 days intervals during 12 months, was caracterized by high individual variability. No seroreversion was observed and there were higher titers in the group of animals which delivered kids and established a lactation period (n=6; mean titre=913.4 units) compared to the group of goats that failed to conceived (n=4; mean titre=261.2 units) (p&lt;0.01).
