Abstract
The infl uence of physical and psychological stress on the concentration in plasma of the acute phase protein haptoglobin (Hp) was studied in 20 fi ghting cows aged 3 to 6 years. Four groups were prepared, the fi rst one or control group comprised livestock with no apparent stimulation. The other groups corresponded to animals of traditional bull running that were sacrifi ced at 30, 54 and 78 h after the end of the spectacle. The mean serum Hp concentration from control fi ghting cows was 0,093 g/l, while it was 0,13 g/l at 30h, 0,19 g/l at 54 h and 0,5 g/l at 78 h after the end of the spectacle. These results show that in the traditional bull running, Hp concentration is elevated and signifi cant differences are observed at 54 h, although the maximum levels appeared at 78 h. In conclusion, in fi ghting cows the serum hp concentration was more elevated due to a situation of physical and psychological stress and may be a useful indicator of stress levels in the animal.
