ABSTRACT
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 percent), compared to that recorded at the beginning of breeding (17.8 percent)(p<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<0.01)
