Mycoplasmata finding in respiratory organs of cattle at dairy farms

Mycoplasmata finding in respiratory organs of cattle at dairy farms

Veterinarski Glasnik 42(5): 291-295

Four dairy farms were subject to examination for mycoplasmata in cattle respiratory organs, and all four yielded positive. Nasal exudates were tested in 185 cows and mycoplasmata were isolated in 82 exudates (44.32%). Out of the total animals examined most were calves (149), much less heifers (16) and cows (20). The results classified per age of cattle indicated that mycoplasmata findings were most abundant in nasal exudates of calves (74 animals; 50.33%), then in heifers (4; 25%) and cows (3; 15%). The age of animals played a significant role in the spread of mycoplasmata in bovine respiratory organs. Younger calves (15-45 days of age) showed mycoplasmata in 65.0% of cases, elder ones (46-90 days) had less (50.0%) microorganisms; younger heifers (5-8 months) yielded positive in 33.33% of elder (18-24 mnonths) in 20.0% of cases.
