Some Hematological, Biochemical and Pathological Changes in Cattle Suffering from Heat Intolerance (Panting) Syndrome Following Natural Foot and Mouth Disease
The clinical signs of heat intolerance syndrome were observed in 70 Holstein cows in a private farm in Isfahan two months after recovery from foot and mouth disease consequences. The condition was characterized clinically by intolerance to increased environmental temperatures. The other signs were panting، hirsutism، profuse salivation and significantly reduced milk production. Blood samples were collected from 10 diseased cows with FMD record، 10 apparently healthy cows with FMD record and 10 healthy cows without FMD record. One cow with the sign of severe panting was slaughtered and the samples from her thyroid، adrenal glands and pancreas were taken for the possible pathologic changes. There were significant increase in blood glucose and phosphorus with a decrease in T3 concentration and neutrophils count in cows with heat intolerance. Pathological changes were necrosis in the thyroid، adrenal glands and pancreas cells. This seems to be the first report in Iran to describe the clinical، pathological and haematobiochemical changes in heat intolerance syndrome in cattle following foot and mouth disease.
