Despite widespread recognition of animal pain, many routine farm procedures are still performed without analgesia.
Farm animals clearly experience pain from surgical and husbandry procedures. Research using behavioral, physiological, and neurological measures confirms that castration, branding, dehorning, and similar procedures cause real suffering. Yet economic factors and lack of veterinary access lead to most procedures being performed without pain relief. Mandatory analgesia requirements, where implemented, have shown that humane treatment is practically achievable.
