I read somewhere that pigs can devour a human body in a matter of hours, they'll even eat the bones. They can digest the remains in such an efficient manner that the pig's feces will have no trace of human DNA, leaving absolutely no forensic evidence. It's said that's why pig farmers are not to be trusted. I don't know if you being from the Philippines makes any difference at all.
Is the disposal of human remains part of your business plan?
Oh, one last thing: Pigs cannot digest the teeth, so those need to be dealt with separately or else the body could be identified through dental records. Just a heads-up.
