it's mostly from bones and hooves.  i don't know the specifics.  i'm sure it's online somewhere.

Answer 3

It was the hooves  Now when they butcher them they have big trucks that are only for the guts

then another one for the hides and then another one for the leg parts below the knees

and another for the heads

the guts go the rendering plant to be boiled down for dog food and other things like  make up, mascara, lip stick, etc,,,  everything is used ..

candles is made from their parts also

Oh I forgot SHAMPOO TOO

Answer 4

"A hundred years ago, many old horses were killed and sent to the glue factory. But today, most glue is made from the bones and hooves of cattle, which thanks to the fast-food burger places, there are a lot of these by-products to be used."

Answer 5

When alot of Indians were around a long longgggg long time ago they thought of all the animals as being very important. So when they killed them for the meat, fur, ect. they always used the whole animal. Mostly on the buffao they used the hooves and/or bones for glue.
