Grade B

Procedures which cause moderate anxiety, fear, pain, or distress for short periods or minor discomfort or distress for long periods.

For instance: recovery from major surgeries like opening and closing the rib-cage, bone operations, or removal of the uterus or gall bladder, done under general anaesthetic and with effective use of pain killers after the operation; surgical procedures on conscious animals but with the use of local anaesthetics to prevent pain during the operation and other pain killers after it; movement of excitable free-range domesticated livestock to unfamiliar housing.

Moderate suffering or noxiousness. Procedures require good justification.
