PT journal article

AB Blood samples were collected during exsanguination from a group of 36 cattle slaughtered at a research abattoir and from a group of 36 cattle slaughtered at a commercial abattoir. Beta-endorphin and cortisol values were measured in plasma from all blood samples. The mean beta-endorphin values for the two groups of animals (19.2 and 20.9 pmol/litre) did not differ significantly. The mean cortisol values for the two groups of cattle did differ significantly (P<0.001) with the commercial abattoir group having the greater mean value (123 nmol/litre versus 41 nmol/litre). Although the commercial abattoir group had an elevated mean cortisol value there were no dark cutting carcasses in the group.
