Glue made out of horses?

Question

do they still do this, or do they use other materials?

Answer 1

it was just the hooves used for glue

Answer 2

yes they still make glue from animal parts (not only horses but anything with hard hooves like cows, goats, sheep, etc). it's not a common practise anymore and there are other ways to make glue, but animal products are still used in some formulas

Answer 3

im pretty sure it was just the hooves and the rest went to dog food or something...i hope they dont still do that!
