The core is more of a member of the supporting cast during squats and deadlifts. You're not going to "get big" abs from those alone.
Definitely no need for an ab day... your time would be better spent working out the rest of your body. Instead you should work in 2-4 core exercises at the end of every resistance training day.
I've not seen anyone bring up the fact that if you're working for big abs, you'd better be working your lower back as well. Also strengthened during some of the more intensive exercises like squats, you still need to dedicate time and effort to strengthen your Erector Spinae and gluts to promote muscle balance.
a few of my favorites are:
-weighted slow crunches on stability ball
-v-ups
-weighted back extensions on stability ball
-planks and bridges
-straight leg deadlift
-leg raises
-the gambit of medicine ball and other plyometric abdominal training
-deep wall abdominal activation during all my resistance training
A key to remember here is to train how you are going to use them. If you're goal is to build muscle for the sake of building muscle, slow and steady wins the race (long concentric and eccentric phases, unless you do a lot of powerlifting) whereas in training for sport, you'd probably be better suited to plyometric abdominal training. In both cases, technique should be the focus.
