Investigation was carried out in response to a report of mortality among Jersey crossbred dairy cattle at Therkumedu village, Tirunelveli district which were purchased from Chittoor district, Andhra Pradesh. Clinical examination was carried out in 38 animals. Most of the animals showed signs of general weakness, dullness, anaemia, icteric mucus membrane, lymphadenopathy, acariasis, bruxism, debility and passing semisolid faeces coated with mucus. Blood smear examination revealed the presence of T. annulata piroplasm and A. marginale inclusions. All the affected animals were treated with Buparvaquone @ 2.5 mg/kg and Oxytetracycline @ 20 mg/kg for 7 days supported with parenteral haematinics (Tribivet) and liver extract. Control of ectoparasites was effected with cypermethrin @ 0.2 per cent as external application and 0.4 per cent spray in animal sheds. All the treated animals recovered slowly and became normal.
