What is your definition of throwaway meat?
Meat that wasn't specifically raised for slaughter. As is the case with you breeder mares. they are raised to breed, after they're doe breeding, they're trash to the owners, so instead of just throwing it away, they sell them cheap to the slaughter for cheap horse meat.
same reason all beef isn't equal. some is made better than others .
