Resumen
In order to check the possible effect of different stressful situations in the release of different muscular enzymes in fifteen fighting bulls (Bos taurus) divided in three groups according to age, transport characteristics and bullfighting conditions (young bulls fought in a trial bullring and in a portable bullring and bulls fought in a permanent bullring) were used in this study. Samples of blood were taken from all animals. Values of cortisol and CPK, LDH and AST enzymes were obtained from blood samples. A higher CPK and LDH release was detected in young bulls fought in a portable bullring, although statistical differences were not found. The behaviour of the enzyme AST was different from CPK and LDH enzymes, what would indicate, according with the data of the present study, that the values of AST would not be a good indicator of muscular damage or fatigue. This higher muscular damage or fatigue was detected in animals fought in a portable bullring which had not a rest period in pens before the bullfight. In these animals a correlation between the release of cortisol and muscular enzymes was detected.
