Here's a stunning article from the Forward newspaper about livestock ready for the slaughter. The Jewish people have not formally sacrificed according to ancient law for nearly 2000 years, and there are certain legal and logistical challenges to doing so, primary among them that the messiah/mashiah/anointed descendant of the Davidic line has not yet arrived. But these guys are ready, should the need arise.
I would hazard a guess that not too many Conservative rabbis have signed on to this. Happy Pesah!
