Serum/colostrum pairs were collected from 245 ewes in 6 sheep herds which had been determined previously to be infected with MV virus and were tested against maedi-visna infection using AGID test. Positive rates were detected as 3,8-41,2 % in tested flocks. Serum and colostrum samples obtained from 53 sheep were positive for MV virus specific antibodies by AGID test. 16 colostrum samples were negative although serum samples obtained from the same animals were found to be positive for MV antibodies. Of the 245 sera and colostrum pairs tested, there was total agreement of results (+or-) in 229 and disagreement in the results with the other 16 serum/colostrum pairs. Of the latter, all serum samples were positive and all colostrum samples were negative for MV antibodies. This study compared colostrum and serum samples for the determination of MV antibodies using AGID test under field conditions on naturally infected animals and on healthy animals. The results show that colostrum antibodies can be detected using AGID test and that colostrum is a reliable material to determine anti-MV virus antibodies. The procedure can be used for herd diagnosis.
