Objective
To immobilise pigs so that other procedures can be carried out.
Alternatives to animal use for teaching
Use of video presentations.
Details of procedure
Restraint used on pigs should involve the minimum force necessary to complete the procedure. The type of restraint imposed depends on the degree of immobility required and the age/size of the pig.
Under 15kg - mild to strong restraint can be applied by holding the pig in the arms or between the knees.
Over 15kg - mild restraint can be achieved by running the pig into a confined area or by the use of boards to block free movement. Strong restraint is best achieved by the use of a snout rope or snubbing rope. The snout rope can be made of either braided wire, plastic or hemp rope of small diameter. A noose is formed, catching the upper jaw. The rope should be placed well back in the mouth to ensure that the pig cannot dislodge it. The rope is pulled to tighten the loop and usually tied to an immovable object (post). For best effectiveness the rope should be tied with as little slack as possible between the pig and the post, with the pig's head at a normal standing height. The loop should be such that the noose can be quickly loosened and removed when the pig is to be released.
Ensure that the pig is not left tied up for long periods of time. This restraint should only be used for short procedures.
