Abstract

A preliminary serological survey using serum neutralization with microtitration showed that 24 (15.6%) of 154 cattle were seropositive. The seropositive non-pregnant cows were immediately eliminated from the herd and the pregnant cows were isolated and eliminated after parturition. The calves with...
