PAIN MANAGEMENT IN PIGS
cost can greatly limit the ability of
producers within certain countries
to achieve the gold standard for pain
control. In response, our practice has
recommended one of two treatment
protocols: injection of meloxicam
(Metacam for swine) at castration or
oral administration of meloxicam to
mitigate the post-castration pain.
Considering the barriers to
use of a gold standard pain control protocol, in Canada the expectation now is that analgesics
alone are used at castration and
tail docking. A recent study in
Canada using a novel behavioral
analysis tool, shown in the photos, has shown promising results
using injectable analgesics for
pain control post-castration. The

to analyze pain. The study has
shown that piglets given injectable meloxicam (0.4 mg/kg IM,
Metacam for swine, Boehringer
Ingelheim Canada) are significantly faster after castration compared
to piglets given no pain control.
The study specifically looked at
whether there was a difference in
post-procedural pain control when
the meloxicam was given 30 minutes prior to castration versus immediately before castration.
The study showed that there
were no significant differences in
the speed post-castration at any time
