The research was carried out during the capture of the hares. Sixty-six hares (experimental group), coming from fourteen different protected areas of Central Italy, were subjected to blood drawing, control of body temperature, hearth and respiratory rate. The same parameters were contemporaneously obtained from ten hares (about one year old)born and reared in cages and, therefore, with a reduced man-fear (control group). Blood samples (plasma) were analysed for glucose, AST (GOT), ALT (GPT), CK and cortisol concentrations. Results showed that the hares reared in cages presented the highest value of glucose while the wild captured hares showed the lowest value (222mg/dl vs. 153mg/dl, P<0.05). These differences were explained by the runs and the escape-attempts during the captures which causes a strong depletion of carbohydrate resources. The level of AST and respiratory rate resulted higher in females than in males. CK, indicator of muscle damage (myopathy), resulted higher in captured hares. The results obtained during the sanitary monitoring showed that most of captured hares, showing values of glucose and CK differing from the control reared hares, are stressed and, consequently have different potential survivals after traslocation. The pain could probably cause different categories of capture myopathy (peracute, acute, sub-acute and chronic myopathy) which can be graded by the determination of CK and AST.

Abstract
The research was carried out during the capture of the hares. Sixty-six hares (experimental group), coming from fourteen different protected areas of Central Italy, were subjected to blood drawing, control of body temperature, hearth and respiratory rate. The same parameters were contemporaneously obtained from ten hares (about one year old)born and reared in cages and, therefore, with a reduced man-fear (control group). Blood samples (plasma) were analysed for glucose, AST (GOT), ALT (GPT), CK and cortisol concentrations. Results showed that the hares reared in cages presented the highest value of glucose while the wild captured hares showed the lowest value (222mg/dl vs. 153mg/dl, P<0.05). These differences were explained by the runs and the escape-attempts during the captures which causes a strong depletion of carbohydrate resources. The level of AST and respiratory rate resulted higher in females than in males. CK, indicator of muscle damage (myopathy), resulted higher in captured hares. The results obtained during the sanitary monitoring showed that most of captured hares, showing values of glucose and CK differing from the control reared hares, are stressed and, consequently have different potential survivals after traslocation. The pain could probably cause different categories of capture myopathy (peracute, acute, sub-acute and chronic myopathy) which can be graded by the determination of CK and AST.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
