Influence of tongue inspection during cysticercosis diagnosis on some behavioral and physiological stress measures in pigs (Sus scrofa domestica).

摘要

To evaluate the level of stress induced by the tongue inspection method during cysticercosis diagnosis in pigs at 60 and 90 kg, 27 animals were assigned to one of three experimental groups. In the first group (T1), pigs were held with a snout noose. In addition, animals in T2 were subjected to tongue inspection, while in T0, none of the procedures described above were performed. Resistance to be handled and serum cortisol concentration were higher (P<0.05) than those from T0 in T1 and T2 groups, for 60- and 90-kg pigs. Time to return to the feeder observed the same pattern than previous variables in 60-kg pigs, but T1 and T0 were similar (P
