This case report presents investigations of muscle problems in three male water buffaloes (1-2 years) kept extensively (loose housing, pasture). The bulls were presented because of listlessness and increased lying periods. They displayed difficulties to stand up, a stilted gait, and tremor in the legs. The determination of the selenium concentration by the measurement of glutathione peroxidase activity in whole blood samples (EDTA) demonstrated selenium deficiency in all three buffaloes. This confirmed the tentative diagnosis of nutritive myodystrophy due to selenium deficiency. Following a single injection of 1500 mg all-rac-alpha-tocopherol acetate and 11 mg sodium selenite, the bulls recovered clinically. The whole blood samples taken subsequently from seven adult water buffaloes on the farm showed selenium deficiency in all animals. Consequently, slow-release multi-trace element boluses were administered once orally - as far as possible - to all adult animals of the herd. After 1 year, a good to very good selenium supply was observed in all these buffaloes, except for one cow, in which bolus application had failed., Competing Interests: Die Autoren bestätigen, dass kein Interessenkonflikt besteht., (Schattauer GmbH.)

A case of sporadic lymphosarcoma in a cow is described. The animal showed a tumorous mass in the area of the right orbita accompanied by conjunctival oedema. Clinical investigation showed an enlargement of a number of internal and external lymph nodes. Haematological and clinicochemical investigations revealed no alterations besides a slight shift to the right in the white blood picture. Blood serum was negative for antibodies directed against bovine leucosis virus. Necropsy showed leucotic and tumorous alterations in a number of organs.
