Abstract: A pig holder designed to support pigs by their hind legs while performing operations on the pig or while giving treatment to the pig, includes a support frame which mounts to the rails of a ferring crate. A leg holder assembly including two pairs of hooks are secured to the support frame for engagement with the pig's hind legs. Each pair of hooks is adapted to engage with a respective hind leg of the pig and includes one upwardly facing hook and one downwardly facing hook. The spacing between the first and second pairs of hooks may be adjusted to accommodate pigs of different size or to spread the hind legs of the pig to permit access to the pig's abdomen.
