[Some forms of disease associated with impaired locomotion in sheep (author's transl)].

A number of flock diseases in sheep associated with impaired locomotion, which are of importance or may assume importance in the Netherlands, are reviewed. Attention is paid to the following metabolic disorders and deficiencies: acetonaemia, hypocalcaemia, hypomagnesaemia, some forms of osteopathy, enzootic ataxia and cerebrocortical necrosis. The following forms of infectious diseases are described: listeric encephalitis, purulent meningitis following injury to the throat, scrapie, visna, Aujeszky's disease and border disease. Finally, a number of viral forms of encephalitis are discussed, which are of minor importance or negligible in the Netherlands, though they are of importance in neighbouring countries. No attempt was made exhaustively to describe the above diseases. The aetiology and pathogenesis usually were not discussed in greater detail than that required for the diagnosis, treatment and prevention of the disease. Efforts were made to be of some help to the veterinary practitioner in controlling some forms of ovine disease in cases in which this is necessary and possible.
