to handling alone. The percentage of stress vocalizations
occurring during the administration of the treatments was
greater (P , 0.05) in CAS, SHORT and LONG compared with
CON piglets. There was no difference (P . 0.05) in the percentage
of stress vocalizations among CAS, SHORT and
LONG piglets during castration.
Piglets castrated without the topical administration of a
local anesthetic to the wound spent more time (P , 0.05)
lying without contact compared with piglets given a short- or
long-acting topical anesthetic after castration. The time
spent lying without contact did not differ (P . 0.0.5) among
control piglets and piglets castrated with or without an
anesthetic (CON: 1.1 6 0.51, CAS: 1.7 6 0.51, SHORT:
0.8 6 0.51 and LONG: 0.3 6 0.51). There was no time by
treatment interaction (P . 0.05) for the time spent lying
