Influence of pre-sampling handling duration on selected biochemical indices in the common pheasant (Phasianus colchicus).

摘要

The effects of varying periods of pre-sampling handling (1.5, 3, 4.5 and 6 min) on selected biochemical indices were monitored in a group of 8-9-month-old common pheasants (Phasianus colchicus) kept at a pheasantry in Jinacovice, Czech Republic. The duration of pheasant handling (capture, restraint, and blood sampling) was positively correlated with plasma corticosterone (p<0.001) and lactate (p<0.05) levels. Negative correlations were found between the handling duration and glucose concentration (p<0.01), and aspartate aminotransferase level (p<0.05) in the blood plasma. A significant increase in corticosterone plasma concentrations and a decrease in glucose plasma concentrations were already found in blood samples taken after 3 min of capture when compared with blood samples of pheasants taken at 1.5 min. It is suggested that blood samples should not collected within 1.5 min of presampling handling to ensure that the levels of the monitored biochemical indices in common pheasants will not be affected by stress induced by pre-sampling handling.
