Regarding all the other animals named in the Mishnah, they are left to graze as you can't visually discern a qualified animal from an unqualified one. But can't you visually discern the difference re the hybrid? If so, why is it left to graze?

Obviously, if it would have been discernable, then it would not have become mixed up. However, it is genetically possible for a hybrid to retain the characteristics of one parent.
