SUMMARY Neonatal haemolytic disease was diagnosed in a Bos indicus cross bred beef herd in south‐east Queensland. The evidence suggested that this was due to B. argentina vaccination for babesiosis while non‐pregnant or less than one month pregnant. The cows received 5 or 6 vaccinations during their breeding life, which indicated that antibody levels can persist for long periods. The autopsy, histopathological and haematological findings indicated that the mechanism was disseminated intra‐vascular coagulation which occurred in calves dying within 24 hours of birth. This resulted in fibrin deposition in pulmonary capillaries and severe pulmonary oedema.
