When anesthetizing a pot-bellied pig, we use a mask made from a plastic gallon jug. To make the mask, we clean the jug, cut
the bottom off, and cover the edges with tape (white adhesive or duct tape works). We then tape a 90-degree anesthesia port
into the top opening of the jug. When inducing anesthesia, a nonrebreathing hose is attached to the port, and we use the jug
handle to hold the mask in place.
Pigs seem to prefer to travel backward when being handled, so when inducing anesthesia, we back the pig into a corner, keeping
our portable, rolling anesthesia machine in tow. The pig usually goes under quickly, taking about 10 big breaths in the mask.
