The adage "use the whole buffalo" has never really died out in terms of meat processing. There's a lot of good product in an animal and you can find buyers for all of it. There's the obvious stuff like hotdogs, sure, but even stuff like the blood is also important. Fetal bovine serum, a supplement for cell culture media, for example comes from the slaughterhouse and is extremely important for biomedical research.
