I take it you're on about the book by george orwell and not the dubious porn film series of the same name!!!!
Mr jones was the owner of Manor farm which changed its name to animal farm when the animals rebelled and drove the farmer out!.....However.......the animals did not collectively own the farm as the pigs (napoleon, squealer, snowball etc) who considered themselves more intelligent than the other animals, took over the leadership of the farm.
Therefore, the pigs owned animal farm.
