This is Axel's Talisman. he wears it around because it reminds him not only of the land he has inherited, but his family and how long it's taken them to ge this far in the farm. Axel has a close relationship with his animals and thats why he chooses to wear the tag along with them, it reminds him of home. The top number represents the generations that have owned the farm, while the bottom number represents the amount of acres he owns. Each on one of Axels children will also have cow tags if they please.
