In most European countries it is common practise to surgically castrate male piglets in order
to avoid pork with boar taint. This painful procedure is discussed in many ways, because the
Austrian and European law allows a castration without anaesthesia I analgesia till the age of
seven days. Many studies are searching for a satisfactory alternative solution to the castration
without pain management. One possibility is the pre-emptive use of analgesics for the
reduction of pain induced by castration. In this investigation the influence of pre-emptive
analgesia by administering meloxicam on postoperative behaviour should be considered.
