There will probably be some pain where the head is cut off, and not having a functional body is not fun, however how will the body feels pain is a much more complex question. Perhaps the pain will be unbearable, perhaps the new body will be incapable of feeling pain at all. Weird sensation are to be expected but will it be painful ?
A lot of research is being done about pain, and maybe one day, this research will also benefit animals. Genetically modifying lab animals so that don't feel pain maybe. Some people don't feel pain at all, and others are literally fearless, these are dangerous medical conditions but these are clearly useful traits in some situations.
But for now, "cruel" animal testing is a necessity if we want medicine to advance and make further testing less painful... Unless we bring back Josef Mengele.
