[Salinomycin poisoning in a Polish stud horse]. / Salinomycinvergiftung in einem polnischen Pferdebestand.

24 cases of salinomycin poisoning in horses occurring recently in Silesia are discussed. All of these horses, used for riding-purposes, were fed with concentrate containing 61 mg/kg salinomycin as faulty prepared by the manufacturer. Each horse received approximately two to three kilograms of this forage. All horses developed severe clinical signs of intoxication. Despite therapy eight horses died within three to six days. Ten others became recumbent and had to be euthanased. Only six horses survived. Clinical and laboratory examinations were performed and are discussed. Laboratory examination of blood included red blood cell count, haematocrit, concentration of haemoglobin, enzyme activities of ASAT, ALAT and AP, also levels of urea, creatinine, sodium, potassium, magnesium, calcium and inorganic phosphor. Blood gas was also analysed. The dominating laboratory results were very high enzyme levels and alkalosis. The most characteristic clinical change appeared as paralysis of the hindlimbs.

An abdominal tumor was suspected after clinical evaluation in an eight-year-old, bay-coloured hannoveranian gelding. The diagnosis was based on the symptoms of ascites, on the results of the transcutaneous abdominal ultrasound examination and on the characteristic changes in the serum-electrophoresis. Postmortem a peritoneal mesothelioma was diagnosed. This primary tumor of the peritoneum is rarely described in horses.
