Do most introductory QFT books contain QED treatment?

I do know that most books contain introductory treatment on QCD, but not usre on QED.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

Yes, it usually is. I would not say that introductory courses teach you much about QCD, rather they start with scalar fields and QED.

As the bosonic part of QED is based on a simpler gauge theory than the Yang-Mills theory for QCD, you actually want to learn QED first. (There is only the one-dimensional Lie-Group U(1) <=> one photon, SU(3) <=> 8 gluons)

@War: In the very most cases yes (as I wrote in the answer above, didn't I?). Right now I don't see anything that is more complicated in QED than it would be in QCD. In any case, the Feynman diagrams are simpler. – Nick Kidman Oct 16 '12 at 8:27
