Clinical signs of heat intolerance (panting)
syndrome were observed in Holstein cows in a private
farm in Egypt. There were heat intolerance (fever), panting,
profuse salivation, hirsutism, lameness and reduced milk
production. Blood and serum samples were collected from
ten diseased cows and five apparently healthy cows as
control. Serological tests confirmed the presence of nonstructural
protein of foot-and-mouth disease (FMD) infection.
There were significant reductions in the total red blood
cell count with increased leucocytic and lymphocytic
counts in diseased group compared to control. The serum
Na, Cl, Ca, Mg, Zn and Fe were significantly reduced but P
was increased in diseased animals compared to control. The
total protein, albumin, cholesterol and cortisol were
significantly reduced but the glucose and malonaldehyde
were significantly increased in diseased cows. This was the
first report in Egypt to describe the clinical and haematobiochemical
changes in panting syndrome following FMD.
