title: [Effects of stress on relative leukocyte frequency and serum sodium and potassium concentrations in bovines].
abstract: The leucocyte and mineral profile changes were studied in bovines with different waiting time at the slaughterhouse. The stress induced by the waiting time at the slaughterhouse brought changes in relative leukocyte frequency, with inverted neutrophil:lymphocyte relation in animals with 24 hours of waiting time (1.45). However the sodium:potassium relation in the animals with 48 hours of waiting time was significantly lower (23.6, p < 0.001) than that almost normal in animals with 24 hours of waiting time (33.1). Also the high correlations between the parameters studied show an unique physiological or pathological situation. The found values point out hormonal changes similar to those in stress situations.
