How do you hold a pig receiving an injection?

A piglet is relatively easy, as you can cradle the piglet in your arms then inject into the semitendinosus muscle. An adult pig is much more challenging - you need to contain the pig into an area you can get close enough to inject fast enough before the pig gets away. Most commercial hog farms have a chute that the pig can stand in but not turn sideways with drop-down doors that keep the pig from walking forwards or backwards.
