Looked it up.

"It is illegal to transport feral pigs in Alabama. Transporting live feral swine is prohibited by law to prevent the spread of the invasive species, and any trapped or captured feral swine must be killed on the spot. The only exception is if you have a special permit from the Alabama Department of Conservation and Natural Resources, or if the feral swine are transported across state lines under a permit issued by the Alabama Department of Agriculture and Industries."
