[LOTR] Why didn't Sauron breed Uruk-Hai?

He knew what Saruman was up to, so he would have the know-how. Uruk-Hai are superior to orcs in every way: taller, stronger, faster, and most importantly, they can move in sunlight. Why didn't Sauron go with them?

Two points:

1. All orcs can move in sunlight, most of them just strongly dislike it.
2. Sauron had larger Uruks as well, though the movies make such a big deal out of Saruman's Uruk-hai that you might think Sauron had none.
