I would have to agree with that opinion, Mayberry Saint.
Of course everyone wants animals to have the least amount of suffering possible, but to have a blanket ruling about "common practices" can encompass a lot of things we don't want to lose the right to do. Like castration of our own pigs, administering our own injections, clipping milk teeth of piglets, removing spurs, even doing our own wound care, etc.
As usual the government manages to miss the point entirely. Instead of targeting the most prevalent violators~ the factory farms~ they make a blanket ruling that could trickle down to the backyard growers. It seems to cover a lot of territory with its vague references and could mean a lot of restrictions for us folks as well.
