An eradication program in a leukosis herd (80% positive) was designed since 1978, and performed successfully from 1982 to 1986 by checking BLV antibodies and generous segregation of positive cattle from the negatives. Slaughter of the positives were in due order, and good milk yield was resulted. The results obtained would be a good model of eradication program with the least economic loss.
