In the second part the authors present a successful MVV eradication by selection method in a large scale Suffolk herd of 248 sheep. The course of infection was monitored by serological examinations at the beginning twice a year and during the four years following re-infection once a year. The tests were performed first by AGID-, and later by ELISA-method. Positive animals were separated with their progenies from the negative animals, for the separation first 2.5 m wide panels were used in the same building, and from the 3rd year the infected sheep were moved to another holding. During the survey examinations the infection was 22.88%, which decreased gradually first and following the re-introduction of infected animals it increased again. The herd became seronegative in the 22nd month after the removal of infected animals to separate holding and in the four examinations during the following 41 months no infected animal was found. Comparing the production parameters in the free and infected herds (average births, suckling lamb losses, yearly ewe losses, weaned lambs per ewe and weight gain) they found that from the 4th year the data were better for all examined parameters in the free herd than in the infected group. On the basis of results they concluded that the production of the herd becomes more economic with MVV-eradication.
