title: [Adrenocortical activity in pigs in relation to nutrition, body weight mycobacteriosis and pre-slaughter stress].
abstract: In 115 pigs divided into 10 groups, with different nutrition levels or with experimentally evoked atypical mycobacteriosis, during the experiments or at slaughter the concentration of 11-hydroxycorticosteroids (11-OHCS) in blood plasma, relative weight of adrenal glands and liver were determined. The increase in adrenocortical function was proved in the cases when the body weight was significantly influenced by malnutrition, and then in the pigs at slaughter, even after relatively careful handling. No changes were found in the course of mycobacteriosis. The relative weight of adrenal glands in slaughtered pigs of lower body weight was higher than that in the pigs of the same age, but of higher body weight. On the other hand, the slaughtered pigs of higher body weights tended to have higher 11-OHCS concentrations. The prolonged stay of the pigs in slaughter houses before bleeding did not result in the increased 11-OHCS levels. The quality of meat was not affected.
