Though not everyone keeps sheep for meat, those who do will be aware that there are by-products from the abattoir which in most cases do not come back to the producer. The most obvious are the skins, along with horns and offal usually. Abattoirs sell these products elsewhere into the relevant trade but is possible to get skins back for tanning.
There are a few areas of red tape that have to be considered when sending sheepskins to the tannery. This is mainly due to the foot-and-mouth outbreak in 2001, along with strict rules regarding movement, skins were no longer permitted back on the holding that the animal came from. However, since then the Animal By-Product Regulations came into effect which allows individuals to collect fresh skins from the abattoir. In most cases an AB117 form needs to be complete to ensure that your skins are returned to be tanned.
